ac191bcb0f bus: mhi: host: Add MHI_PM_SYS_ERR_FAIL state
[ Upstream commit bce3f77068 ]

When processing a SYSERR, if the device does not respond to the MHI_RESET
from the host, the host will be stuck in a difficult to recover state.
The host will remain in MHI_PM_SYS_ERR_PROCESS and not clean up the host
channels.  Clients will not be notified of the SYSERR via the destruction
of their channel devices, which means clients may think that the device is
still up.  Subsequent SYSERR events such as a device fatal error will not
be processed as the state machine cannot transition from PROCESS back to
DETECT.  The only way to recover from this is to unload the mhi module
(wipe the state machine state) or for the mhi controller to initiate
SHUTDOWN.

This issue was discovered by stress testing soc_reset events on AIC100
via the sysfs node.

soc_reset is processed entirely in hardware.  When the register write
hits the endpoint hardware, it causes the soc to reset without firmware
involvement.  In stress testing, there is a rare race where soc_reset N
will cause the soc to reset and PBL to signal SYSERR (fatal error).  If
soc_reset N+1 is triggered before PBL can process the MHI_RESET from the
host, then the soc will reset again, and re-run PBL from the beginning.
This will cause PBL to lose all state.  PBL will be waiting for the host
to respond to the new syserr, but host will be stuck expecting the
previous MHI_RESET to be processed.

Additionally, the AMSS EE firmware (QSM) was hacked to synthetically
reproduce the issue by simulating a FW hang after the QSM issued a
SYSERR.  In this case, soc_reset would not recover the device.

For this failure case, to recover the device, we need a state similar to
PROCESS, but can transition to DETECT.  There is not a viable existing
state to use.  POR has the needed transitions, but assumes the device is
in a good state and could allow the host to attempt to use the device.
Allowing PROCESS to transition to DETECT invites the possibility of
parallel SYSERR processing which could get the host and device out of
sync.

Thus, invent a new state - MHI_PM_SYS_ERR_FAIL

This essentially a holding state.  It allows us to clean up the host
elements that are based on the old state of the device (channels), but
does not allow us to directly advance back to an operational state.  It
does allow the detection and processing of another SYSERR which may
recover the device, or allows the controller to do a clean shutdown.

When the range parsing was open-coded the number of u32 entries to
parse had to be a multiple of 4 and the driver checks this. With
the range parsing converted to the range parser the counting changes
from individual u32 entries to a complete range, so the check must
not reject counts not divisible by 4.

commit 01bd694ac2 upstream.

Ensure read and write locks for the channel are not taken in succession by
dropping the read lock from parse_xfer_event() such that a callback given
to client can potentially queue buffers and acquire the write lock in that
process. Any queueing of buffers should be done without channel read lock
acquired as it can result in multiple locks and a soft lockup.

a9ebfc405f bus: mhi: host: Add alignment check for event ring read pointer
commit eff9704f53 upstream.

Though we do check the event ring read pointer by "is_valid_ring_ptr"
to make sure it is in the buffer range, but there is another risk the
pointer may be not aligned.  Since we are expecting event ring elements
are 128 bits(struct mhi_ring_element) aligned, an unaligned read pointer
could lead to multiple issues like DoS or ring buffer memory corruption.

So add a alignment check for event ring read pointer.

Let's fix this by flushing the posted write only after the reset delay.
We do flushing also for ti,sysc-delay-us using devices as that should

d31d14bf07 Revert "drivers: bus: simple-pm-bus: Add support for probing simple bus only devices"
This reverts commit 98e96cf800.

The following commit introduced in v5.15-rc6 breaks i.MX8QM/QXP
suspend/resume. The issue was reported in community [1] and still under
discussion and not conclusion on the proper fix so far.

This patch temporarily revert it in order to make the release work.
i.MX seems not use .sync_state() mentioned in the original commit,
suppose it may be safe as we also havn't used it before.

e5deb8f76e bus: ti-sysc: Fix SYSC_QUIRK_SWSUP_SIDLE_ACT handling for uart wake-up
The uarts should be tagged with SYSC_QUIRK_SWSUP_SIDLE instead of
SYSC_QUIRK_SWSUP_SIDLE_ACT. The difference is that SYSC_QUIRK_SWSUP_SIDLE
is used to force idle target modules rather than block idle during usage.

The SYSC_QUIRK_SWSUP_SIDLE_ACT should disable autoidle and wake-up when
a target module is active, and configure autoidle and wake-up when a
target module is inactive. We are missing configuring the target module
on sysc_disable_module(), and missing toggling of the wake-up bit.

Let's fix the issue to allow uart wake-up to work.

11729caa52 bus: ti-sysc: Fix missing AM35xx SoC matching
Commit feaa8baee8 ("bus: ti-sysc: Implement SoC revision handling")
created a list of SoC types searching for strings based on names
and wildcards which associates the SoC to different families.

The OMAP34xx and OMAP35xx are treated as SOC_3430 while
OMAP36xx and OMAP37xx are treated as SOC_3630, but the AM35xx
isn't listed.

The AM35xx is mostly an OMAP3430, and a later commit a12315d6d2
("bus: ti-sysc: Make omap3 gpt12 quirk handling SoC specific") looks
for the SOC type and behaves in a certain way if it's SOC_3430.

This caused a regression on the AM3517 causing it to return two
errors:

 ti-sysc: probe of 48318000.target-module failed with error -16
 ti-sysc: probe of 49032000.target-module failed with error -16

Fix this by treating the creating SOC_AM35 and inserting it between
the SOC_3430 and SOC_3630.  If it is treaed the same way as the
SOC_3430 when checking the status of sysc_check_active_timer,
the error conditions will disappear.

d929b2b746 bus: ti-sysc: Use fsleep() instead of usleep_range() in sysc_reset()
The am335x-evm started producing boot errors because of subtle timing
changes:

Unhandled fault: external abort on non-linefetch (0x1008) at 0xf03c1010
...
sysc_reset from sysc_probe+0xf60/0x1514
sysc_probe from platform_probe+0x5c/0xbc
...

The fix consists in using the appropriate sleep function in sysc reset.
For flexible sleeping, fsleep is recommended. Here, sysc delay parameter
can take any value in [0 - 255] us range. As a result, fsleep() should
be used, calling udelay() for a sysc delay lower than 10 us.

1544df9ab4 ARM: SoC drivers for 6.6
The main change this time is the introduction of the drivers/genpd
 subsystem that gets split out from drivers/soc to keep common
 functionality together. Ulf Hansson is taking over maintainership for
 these and is sending a separate pull request with the same commits,
 but they are in the soc drivers tree to avoid conflicts against other
 soc driver patches.
 
 The SCMI driver subsystem gets an update to version 3.2 of the
 specification. There are also updates to memory, reset and other firmware
 drivers.
 
 On the soc driver side, the updates are mostly cleanups across a number
 of Arm platforms. On driver for loongarch adds power management for DT
 based systems, another driver is for HiSilicon's Arm server chips with
 their HCCS system health interface.
 
 The remaining updates for the most part add support for additional
 hardware in existing drivers or contain minor cleanups. Most of these
 are for the Qualcomm Snapdragon platform.

bus: fsl-mc: Use common ranges functions
Since commit 3d5089c426 ("of/address: Add support for 3 address cell
bus"), the DT address functions can handle translating buses with 3
address cells. Replace the custom code with the for_each_of_range()
iterator.

The original code had fallbacks to get "#address-cells"/"#size-cells"
from the bus parent node if they are missing. This is non-standard
behavior, and AFAICT the upstream .dts files never relied on that.

Driver changes for omaps for v6.6

Driver changes for ti-sysc interconnect target module driver and for
l3 interconnect error handler. The ti-sysc driver changes just enable
using it for 64-bit systems like TI am62 that have wake-up capability
for the wkup domain devices. The l3 error handling improves the code
to show the error source if an unrecoverable timeout error occurs.

53c5ae638d
bus: 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.
