ad1081a0da clk: rockchip: fix finding of maximum clock ID
If an ID of a branch's child is greater than current maximum, we should
set new maximum to the child's ID, instead of its parent's.

Remove them for the moment. If they are needed later, they can
be added back at that point.

12fd64baba clk: rockchip: fix error for unknown clocks
There is a clk == NULL check after the switch to check for
unsupported clk types. Since clk is re-assigned in a loop,
this check is useless right now for anything but the first
round. Let's fix this up by assigning clk = NULL in the
loop before the switch statement.

2e7b3daa8c clk: rockchip: rk3588: drop unused code
All clocks are registered early using CLK_OF_DECLARE(), which marks
the DT node as processed. For the processed DT node the probe routine
is never called. Thus this whole code is never executed. This could
be "fixed" by using CLK_OF_DECLARE_DRIVER, which avoids marking the
DT node as processed. But then the probe routine would re-register
all the clocks by calling rk3588_clk_init() again.

721bf080f2 clk: rockchip: rk3568: Mark pclk_usb as critical
In the reference manual under "2.8.6 NIU Clock gating reliance"
it is stated that pclk_usb_niu has a dependency on hclk_usb_niu.

While the manual does not state that this is a bi-directional
relationship it was noted that the sdmmc2 failed to operate for me in
mmc mode if the pclk_usb was not marked as critical. The parent clock
of the hclk_sdmmc2 is hclk_usb.

99fe9ee56b clk: rockchip: rk3128: Fix SCLK_SDMMC's clock name
SCLK_SDMMC is the parent for SCLK_SDMMC_DRV and SCLK_SDMMC_SAMPLE, but
used with the (more) correct name sclk_sdmmc. SD card tuning does currently
fail as the parent can't be found under that name.
There is no need to suffix the name with '0' since RK312x SoCs do have a
single sdmmc controller - so rename it to the name which is already used
by it's children.

98dcc6be38 clk: rockchip: rk3128: Fix aclk_peri_src's parent
According to the TRM there are no specific gpll_peri, cpll_peri,
gpll_div2_peri or gpll_div3_peri gates, but a single clk_peri_src gate.
Instead mux_clk_peri_src directly connects to the plls respectively the pll
divider clocks.
Fix this by creating a single gated composite.

Also rename all occurrences of aclk_peri_src to clk_peri_src, since it
is the parent for peri aclks, pclks and hclks. That name also matches
the one used in the TRM.

a96cbb146a clk: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
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
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

64042c28c3 clk: rockchip: rk3588: make gate linked clocks critical
RK3588 has a couple of hardware blocks called Native Interface Unit
(NIU) that gate the clocks to devices behind them. Effectively this
means that some clocks require two parent clocks being enabled.
Downstream implemented this by using a separate clock driver
("clk-link") for them, which enables the second clock using PM
framework.

In the upstream kernel we are currently missing support for the second
parent. The information about it is in the GATE_LINK() macro as
linkname, but that is not used. Thus the second parent clock is not
properly enabled. So far this did not really matter, since these clocks
are mostly required for the more advanced IP blocks, that are not yet
supported upstream. As this is about to change we need a fix. There
are three options available:

1. Properly implement support for having two parent clocks in the
   clock framework.
2. Mark the affected clocks CLK_IGNORE_UNUSED, so that they are not
   disabled. This wastes some power, but keeps the hack contained
   within the clock driver. Going from this to the first solution
   is easy once that has been implemented.
3. Enabling the extra clock in the consumer driver. This leaks some
   implementation details into DT.

This patch implements the second option as an intermediate solution
until the first one is available. I used an alias for CLK_IS_CRITICAL,
so that it's easy to see which clocks are not really critical once
the clock framework supports a better way to implement this.

645a5198dd clk: rockchip: Remove values for mmask and nmask in struct clk_fractional_divider
Now that fractional_divider clk computes mmask and nmask when needed, there
is no more need to provide them explicitly anymore.
