Jeffrey HugoandGreg Kroah-Hartman 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

the range parsing converted to the range parser the counting changes
from individual u32 entries to a complete range, so the check must

commit b89b6a863d upstream.

Protect WP accesses such that multiple threads queueing buffers for

Meanwhile, if CONFIG_TRACE_IRQFLAGS is enabled, irq will be enabled once
__local_bh_enable_ip is called as part of write_unlock_bh. Hence, let's
take irqsave lock after TRE is generated to avoid running write_unlock_bh
when irqsave lock is held.

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

acquired as it can result in multiple locks and a soft lockup.

Krishna chaitanya chundruandGreg Kroah-Hartman 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.

Commit 34539b442b ("bus: ti-sysc: Flush posted write on enable before

target module can produce interconnect errors on boot. Turns out the
registers are not accessible until after a delay for devices needing
a ti,sysc-delay-us value.

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
trigger an interconnect error if the delay is not properly configured.

Let's also add some comments while at it.

The uarts should be tagged with SYSC_QUIRK_SWSUP_SIDLE instead of

The SYSC_QUIRK_SWSUP_SIDLE_ACT should disable autoidle and wake-up when

target module is inactive. We are missing configuring the target module
on sysc_disable_module(), and missing toggling of the wake-up bit.

Adam FordandTony Lindgren 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.

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.

Rob HerringandArnd Bergmann 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.

Kalle ValoandManivannan Sadhasivam efe47a18e4 bus: mhi: host: allow MHI client drivers to provide the firmware via a pointer
Currently MHI loads the firmware image from the path provided by client
devices. ath11k needs to support firmware image embedded along with meta
data (named as firmware-2.bin). So allow the client driver to request the
firmware file from user space on it's own and provide the firmware image
data and size to MHI via a pointer struct mhi_controller::fw_data.

This is an optional feature, if fw_data is NULL MHI load the firmware using
the name from struct mhi_controller::fw_image string as before.

Tested with ath11k and WCN6855 hw2.0.
