So we need to set spdif clock to a proper rate. which make asrc

The target is spdif clock rate / output(or input) sample rate

Back-to-back LPCG writes can be ignored by the LPCG register due to
a HW bug. The writes need to be seperated by at least 4 cycles of
the gated clock.
The workaround is implemented as follows:
1. For clocks running greater than or equal to 24MHz, a read
followed by the write will provide sufficient delay.
2. For clocks running below 24MHz, add a delay of 4 clock cylces
after the write to the LPCG register.

We are using a wrong mcbsp functional clock. The interconnect target module
driver provided clock for mcbsp is not same as the mcbsp functional clock
known as the gfclk main_clk. The mcbsp functional clocks for mcbsp should
have been added before we dropped the legacy platform data.
Additionally we are also missing the clock aliases for the clocks used by
the audio driver if reparenting is needed. This causes audio driver errors
like "CLKS: could not clk_get() prcm_fck" for mcbsp as reported by Andreas.
The mcbsp clock aliases too should have been added before we dropped the
legacy platform data.
Let's add the clocks and aliases with a single patch to fix the issue
similar to omap4. On omap5, there is no mcbsp4 instance on the l4_per
interconnect.

Additionally we are also missing the clock aliases for the clocks used by
the audio driver if reparenting is needed. This causes audio driver errors
like "CLKS: could not clk_get() prcm_fck" for mcbsp as reported by Andreas.
The mcbsp clock aliases too should have been added before we dropped the
legacy platform data.
Let's add the clocks and aliases with a single patch to fix the issue.

In the possible_parent_show function, ensure proper handling of the return
value from of_clk_get_parent_name to prevent potential issues arising from
a NULL return.
The current implementation invokes seq_puts directly on the result of
of_clk_get_parent_name without verifying the return value, which can lead
to kernel panic if the function returns NULL.
This patch addresses the concern by introducing a check on the return
value of of_clk_get_parent_name. If the return value is not NULL, the
function proceeds to call seq_puts, providing the returned value as
argument.
However, if of_clk_get_parent_name returns NULL, the function provides a
static string as argument, avoiding the panic.

Commit 9607beb917 ("clk: socfpga: gate: Add a determine_rate hook")
added a determine_rate implementation set to the
clk_hw_determine_rate_no_reparent, but failed to account for the
internal divider that wasn't used before anywhere but in recalc_rate.
This led to inconsistencies between the clock rate stored in
clk_core->rate and the one returned by clk_round_rate() that leverages
determine_rate().
Since that driver seems to be widely used (and thus regression-prone)
and not supporting rate changes (since it's missing a .set_rate
implementation), we can just report the current divider programmed in
the clock but not try to change it in any way.
This should be good enough to fix the issues reported, and if someone
ever wants to allow the divider to change then it should be easy enough
using the clk-divider helpers.

Rework the write operation such that the Byte Count register is written with
a single raw i2c write outside of regmap using transfer which does specify
the number of bytes to be transfered, one in this case, and which makes the
expected subsequent write transfer look like address+register+data, and then
make use of this method. Without this change, the Byte Count register write
in probe() would succeed as it would provide the byte count as part of its
write payload, but any subsequent writes would fail due to this Byte Count
register programming. Such failing writes happens e.g. during resume, when
restoring the regmap content.

In order to reload registers into the clock generator on resume using
regcache_sync(), it is necessary to select one of the regcache types
which are not NONE. Since this device has some 7 registers, use the
simplest one, FLAT. The regcache code complains about REGCACHE_NONE
being selected and generates a WARNING, this fixes that warning.

changes to the clk framework this time around. That's probably because everyone
was on vacation (yours truly included). We did lose a couple clk drivers this
time around because nobody was using those devices. That skews the diffstat a
bit, but either way, nothing looks out of the ordinary here. The usual suspects
are chugging along adding support for more SoCs and fixing bugs.
If I had to choose, I'd say the theme for the past few months has been
"polish". There's quite a few patches that migrate to
devm_platform_ioremap_resource() in here. And there's more than a handful of
patches that move the NR_CLKS define from the DT binding header to the driver.
There's even patches that migrate drivers to use clk_parent_data and clk_hw to
describe clk tree topology. It seems that the spring (summer?) cleaning bug got
some folks, or the semiconductor shortage finally hit the software side.

Problem can be reproduced by unloading snd_soc_simple_card, because in
devm_get_clk_from_child() devres data is allocated as `struct clk`, but
devm_clk_release() expects devres data to be `struct devm_clk_state`.

Since commit b09c68dc57 ("clk: imx: pll14xx: Support dynamic rates"),
the driver has the ability to dynamically compute PLL parameters to
approximate the requested rates. This is not always used, because the
logic is as follows:
- Check if the target rate is hardcoded in the frequency table
- Check if varying only kdiv is possible, so switch over is glitch free
- Compute rate dynamically by iterating over pdiv range
If we skip the frequency table for the 1443x PLL, we find that the
computed values differ to the hardcoded ones. This can be valid if the
hardcoded values guarantee for example an earlier lock-in or if the
divisors are chosen, so that other important rates are more likely to
be reached glitch-free.
For rates (393216000 and 361267200, this doesn't seem to be the case:
They are only approximated by existing parameters (393215995 and
361267196 Hz, respectively) and they aren't reachable glitch-free from
other hardcoded frequencies. Dropping them from the table allows us
to lock-in to these frequencies exactly.
This is immediately noticeable because they are the assigned-clock-rates
for IMX8MN_AUDIO_PLL1 and IMX8MN_AUDIO_PLL2, respectively and a look
into clk_summary so far showed that they were a few Hz short of the target:
imx8mn-board:~# grep audio_pll[12]_out /sys/kernel/debug/clk/clk_summary
audio_pll2_out 0 0 0 361267196 0 0 50000 N
audio_pll1_out 1 1 0 393215995 0 0 50000 Y
and afterwards:
imx8mn-board:~# grep audio_pll[12]_out /sys/kernel/debug/clk/clk_summary
audio_pll2_out 0 0 0 361267200 0 0 50000 N
audio_pll1_out 1 1 0 393216000 0 0 50000 Y

The PLL14xx hardware can be found on i.MX8M{M,N,P} SoCs and always come
with a 6-bit pre-divider. Neither the reference manuals nor the
datasheets of these SoCs do mention any restrictions. Furthermore the
current code doesn't respect the restrictions from the comment too.
Therefore drop the restriction and align the max pre-divider (pdiv)
value to 63 to get more accurate frequencies.

Reconfiguring the clock divider to the exact same value is observed
on an i.MX8MN to often cause a longer than usual clock pause, probably
because the divider restarts counting whenever the register is rewritten.
This issue doesn't show up normally, because the clock framework will
take care to not call set_rate when the clock rate is the same.
However, when we reconfigure an upstream clock, the common code will
call set_rate with the newly calculated rate on all children, e.g.:
- sai5 is running normally and divides Audio PLL out by 16.
- Audio PLL rate is increased by 32Hz (glitch-free kdiv change)
- rates for children are recalculated and rates are set recursively
- imx8m_clk_composite_divider_set_rate(sai5) is called with
32/16 = 2Hz more
- imx8m_clk_composite_divider_set_rate computes same divider as before
- divider register is written, so it restarts counting from zero and
MCLK is briefly paused, so instead of e.g. 40ns, MCLK is low for 120ns.
Some external clock consumers can be upset by such unexpected clock pauses,
so let's make sure we only rewrite the divider value when the value to be
written is actually different.

Selecting the closest rate for pll-video0 instead of the closest rate
that is less than the requested rate has no downside for this clock,
while allowing for selecting a more suitable rate, e.g. for the

Furthermore, the algorithm that sets an NKM clock's parent benefits from
the closest rate. Without it, the NKM clock's rate might drift away from
the requested rate in the multiple successive calls to
ccu_nkm_determine_rate that the clk framework performs when setting a

Therefore, configure pll-video0 and, in consequence, all of its

Let's introduce a new module called meson-clkc-utils that
will contain shared utility functions for all Amlogic clock
controller drivers.
The first utility function is a replacement of of_clk_hw_onecell_get
in order to get rid of the NR_CLKS define in all Amlogic clock
drivers.
The goal is to move all duplicate probe and init code in this module.

Audio REFCLK's are not working correctly, trying to use them lead to the
following errors:
[ 6.575277] of_clk_hw_onecell_get: invalid index 4294934528
[ 6.581515] wm8904 1-001a: Failed to get MCLK
[ 6.586290] wm8904: probe of 1-001a failed with error -2
The issue is that Audio REFCLK has #clock-cells = 0 [1], while the driver
is registering those clocks assuming they have one cells. Fix this by
registering the clock with of_clk_hw_simple_get() when there is only one
instance, e.g. "audio_refclk".

Convert the clock driver to specify parent data rather than parent
names, to actually bind using 'clock-names' specified in the DTS rather
than global clock names. Use parent_hws where possible to refer parent
clocks directly, skipping the lookup.
Note, the system names for xo clocks were changed from "cxo" to
"cxo_board" to follow the example of other platforms. This switches the
clocks to use DT-provided "cxo_board" clock instead of manually
registered "cxo" clock and allows us to drop the cxo clock.

As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and

This reverts commit 860690a93e.
On the MT8183, the SSPM related clocks were removed claiming a lack of
usage. This however causes some issues when the driver was converted to
the new simple-probe mechanism. This mechanism allocates enough space
for all the clocks defined in the clock driver, not the highest index
in the DT binding. This leads to out-of-bound writes if their are holes
in the DT binding or the driver (due to deprecated or unimplemented
clocks). These errors can go unnoticed and cause memory corruption,
leading to crashes in unrelated areas, or nothing at all. KASAN will
detect them.
Add the SSPM related clocks back to the MT8183 clock driver to fully
implement the DT binding. The SSPM clocks are for the power management
co-processor, and should never be turned off. They are marked as such.

This series reshuffles things around, moving the management of SMD RPM
bus clocks to the interconnect framework where they belong. This helps
us solve a couple of issues:
1. We can work towards unused clk cleanup of RPMCC without worrying
about it killing some NoC bus, resulting in the SoC dying.
Deasserting actually unused RPM clocks (among other things) will
let us achieve "true SoC-wide power collapse states", also known as
VDD_LOW and VDD_MIN.
2. We no longer have to keep tons of quirky bus clock ifs in the icc
driver. You either have a RPM clock and call "rpm set rate" or you
have a single non-RPM clock (like AHB_CLK_SRC) or you don't have any.
3. There's less overhead - instead of going through layers and layers of
the CCF, ratesetting comes down to calling max() and sending a single
RPM message. ICC is very very dynamic so that's a big plus.
The clocks still need to be vaguely described in the clk-smd-rpm driver,
as it gives them an initial kickoff, before actually telling RPM to
enable DVFS scaling. After RPM receives that command, all clocks that
have not been assigned a rate are considered unused and are shut down
in hardware, leading to the same issue as described in point 1.
We can consider marking them __initconst in the future, but this series
is very fat even without that..
Apart from that, it squashes a couple of bugs that really need fixing..
The series is merged through a topic branch to manage the dependencies
between interconnect, Qualcomm clocks and Qualcomm SoC.
The interconnect bus clocks are now handled within the ICC framework.
They still however need to get a kickstart *before* we call
clk_smd_rpm_enable_scaling(), or RPM will assume that they should all
be running at 0 kHz and the system will inevitably die.
Separate them out to ensure such a kickstart can still take place.
As a happy accident, the file got smaller:

icc_smd_rpm will do bus clock votes itself rather than taking the
unnecessary detour through the clock subsystem. However, it can only
do that after the clocks have been handed off and scaling has been
enabled in the RPM in clk-smd-rpm.
Move the icc_smd_rpm registration from smd-rpm.c to clk-smd-rpm.c
to avoid any possible races. icc_smd_rpm gets the driver data from
the smd-rpm device, so still register the platform device on the
smd-rpm parent device.

A clock used for the 3D graphics appears to be common
among multiple SoC's, so add a generic gen3 clock
for clocking the graphics. This is similar to the
cpg_z_clk, with a different frequency control register
and different flags. Instead of duplicating the code,
make cpg_z_clk_register into a helper function and
call the help function with the FCR and flags as
a parameter.

There are two new SoC families this time, and both appear fairly similar:
The Nuvoton MA35D1 and the STMicroelectronics STM32MP2 are both dual-core
Cortex-A35 based chips for the low-power industrial embedded market,
and they mark the first 64-bit product in a widely used family of 32-bit
Arm MCUs and SoCs.
The way into the kernel is completely different here: The team at ST has
a long history of working upstream with their STM32MP1 and other SoCs,
and they produced a complete port to arm64 together with the initial
announcement. Nuvoton also has multiple SoC product lines with current
or previous upstream support, but those are maintained by third parties

Pull new ARM SoC support from Arnd Bergmann:
"There are two new SoC families this time, and both appear fairly
similar: The Nuvoton MA35D1 and the STMicroelectronics STM32MP2 are
both dual-core Cortex-A35 based chips for the low-power industrial
embedded market, and they mark the first 64-bit product in a widely
used family of 32-bit Arm MCUs and SoCs.
The way into the kernel is completely different here: The team at ST
has a long history of working upstream with their STM32MP1 and other
SoCs, and they produced a complete port to arm64 together with the
initial announcement. Nuvoton also has multiple SoC product lines with
current or previous upstream support, but those are maintained by
third parties and are unrelated. The patch series from Nuvoton's Jacky
Huang had to go through many revisisions to get to this point and is
still missing a few drivers including the serial port for the moment.

SoC support. Instead there's a treewide patch series from Maxime that makes
clk_ops::determine_rate mandatory for muxes. Beyond that core framework change
we have the usual pile of clk driver updates such as migrating i2c drivers to
use .probe() again or YAMLfication of clk DT bindings so we can validate DTBs.
Overall the SoCs that got the most updates this time around in terms of
diffstat are the Amlogic and Mediatek drivers because they added new SoC
support or fixed up various drivers to have proper data.
In general things look kinda quiet. I suspect the core framework change may
still shake out some problems after the merge window, mostly because not
everyone tests linux-next where that series has been for some number of weeks.
I saw that there's at least one pending fix for Tegra that needs to be wrapped
up into a proper patch. I'll try to catch those bits before the window closes
so that -rc1 is bootable. More details below.
Core:
- Make clk_ops::determine_rate mandatory for muxes
New Drivers:
- Add amlogic a1 SoC family PLL and peripheral clock controller support
Updates:
- Handle allocation failures from kasprintf() and friends
- Migrate platform clk drivers to .remove_new()
- Migrate i2c clk drivers to .probe() instead of .probe_new()
- Remove CLK_SET_PARENT from all Mediatek MSDC core clocks
- Add infra_ao reset support for Mediatek MT8188 SoCs
- Align driver_data to i2c_device_id tables in some i2c clk drivers
- Use device_get_match_data() in vc5 clk driver
- New Kconfig symbol name (SOC_MICROCHIP_POLARFIRE) for Microchip FPGA clock
drivers
- Use of_property_read_bool() to read "microchip,pic32mzda-sosc" boolean DT
property in clk-pic32mzda
- Convert AT91 clock dt-bindings to YAML
- Remove CLK_SET_RATE_PARENT flag from LDB clocks on i.MX6SX
- Keep i.MX UART clocks enabled during kernel boot if earlycon is set
- Drop imx_unregister_clocks() as there are no users anymore
- Switch to _safe iterator on imx_clk_scu_unregister() to avoid use after free
- Add determine_rate op to the imx8m composite clock
- Use device managed API for iomap and kzalloc for i.MXRT1050, i.MX8MN,
i.MX8MP and i.MX93 clock controller drivers
- Add missing interrupt DT property for the i.MX8M clock controller
- Re-add support for Exynos4212 clock controller because we are
re-introducing the SoC in the mainline
- Add CONFIG_OF dependency to Samsung clk Kconfig symbols to solve some
objtool warnings
- Preselect PLL MIPI as TCON0 parent for Allwinner A64 SoC
- Convert the Renesas clock drivers to readl_poll_timeout_atomic()
- Add PWM clock on Renesas R-Car V3U
- Fix PLL5 on Renesas RZ/G2L and RZ/V2L
