An HBM memory channel is divided into two pseudo channels. Each
pseudo channel has its own retry_rd_err_log registers. Retrieve and
print retry_rd_err_log registers of the HBM pseudo channel if the
memory error is from HBM.

Each pseudo channel of HBM has its own retry_rd_err_log registers.
The bit 0 of ChipSelect ADXL component encodes the pseudo channel
number of HBM memory. So add ChipSelect ADXL component to get HBM
pseudo channel number.

Pull driver core fixes from Greg KH:
"Here are two tiny driver core fixes for 6.0-rc7 that resolve some
oft-reported problems.
The first is a revert of the "fw_devlink.strict=1" default option that
we keep trying to enable, but we keep finding platforms that this just
breaks everything on. So again, we need it reverted and hopefully it
can be worked on in future releases.
The second is a sysfs file-size bugfix that resolves an issue that
many people are starting to hit as the fix it is fixing also was
backported to stable kernels. The util-linux developers are starting
to get bugreports about sysfs files that contain no data because of
this problem, and this fix which has been in linux-next in the
bitfield tree for a long time, resolves it. I'm submitting it here as
it needs to be merged for 6.0-final, not for 6.1-rc1.
Both of these have been in linux-next with no reported issues, only
reports were that these fixed problems"

Qualcomm driver updates for 6.1
The icc-bwmon driver is expected to support measuring LLCC/DDR bandwidth
on SDM845 and SC7280.
The LLCC driver is extended to provide per-platform register mappings to
the LLCC EDAC driver. The QMI encoder/decoder is updated to allow the
passed qmi_elem_info to be const.
Support for SDM845 is added to the sleep stats driver. Power-domains for
the SM6375 platform is added to RPMPD and the platform is added to
socinfo, together with the PM6125 pmic id.
A couple of of_node reference issues are corrected in the smem state and
smsm drivers.
The Qualcomm SCM driver binding is converted to YAML.

suspend/resume time"
This reverts commit 211f276ed3d96e964d2d1106a198c7f4a4b3f4c0.
For quite some time, core DRM helpers already ensure that any relevant
connectors/CRTCs/etc. are disabled, as well as their associated
components (e.g., bridges) when suspending the system. Thus,
analogix_dp_bridge_{enable,disable}() already get called, which in turn
call drm_panel_{prepare,unprepare}(). This makes these drm_panel_*()
calls redundant.
Besides redundancy, there are a few problems with this handling:
(1) drm_panel_{prepare,unprepare}() are *not* reference-counted APIs and
are not in general designed to be handled by multiple callers --
although some panel drivers have a coarse 'prepared' flag that mitigates
some damage, at least. So at a minimum this is redundant and confusing,
but in some cases, this could be actively harmful.
(2) The error-handling is a bit non-standard. We ignored errors in
suspend(), but handled errors in resume(). And recently, people noticed
that the clk handling is unbalanced in error paths, and getting *that*
right is not actually trivial, given the current way errors are mostly
ignored.
(3) In the particular way analogix_dp_{suspend,resume}() get used (e.g.,
in rockchip_dp_*(), as a late/early callback), we don't necessarily have
a proper PM relationship between the DP/bridge device and the panel
device. So while the DP bridge gets resumed, the panel's parent device
(e.g., platform_device) may still be suspended, and so any prepare()
calls may fail.
So remove the superfluous, possibly-harmful suspend()/resume() handling
of panel state.
Fixes: 211f276ed3d9 ("drm: bridge: analogix/dp: add panel prepare/unprepare in suspend/resume time")

====================
pull-request: can-next 2022-09-23
The first 2 patches are by Ziyang Xuan and optimize registration and
the sending in the CAN BCM protocol a bit.
The next 8 patches target the gs_usb driver. 7 are by me and first fix
the time hardware stamping support (added during this net-next cycle),
rename a variable, convert the usb_control_msg + manual
kmalloc()/kfree() to usb_control_msg_{send,rev}(), clean up the error
handling and add switchable termination support. The patch by Rhett
Aultman and Vasanth Sadhasivan convert the driver from
usb_alloc_coherent()/usb_free_coherent() to kmalloc()/URB_FREE_BUFFER.
The last patch is by Shang XiaoJing and removes an unneeded call to
dev_err() from the ctucanfd driver.

The hardware offloading in MACsec was initially supported using 2 phases.
This was proposed in the RFC as this could have allowed easier fallback
to the software implementation if the hardware did not support a feature
or had enough entries already. But this fallback wasn't implemented and
might not be a good idea after all. In addition it turned out this logic
didn't mapped well the hardware logic and device drivers were mostly
ignoring the preparation phase.
Let's remove this as it does not offer any advantage and is ignored by
drivers.

The SDM630 and SDM660 both use RPM (not RPMh) for managing the PM660 and
PM660L. The SDM670 uses RPMh to manage them as PMIC 4s. To support the
SDM670, add the PM660 and PM660L to the RPMh regulator driver.

This switches the driver to use gpiod API instead of legacy gpio API,
which will brings us close to removing of_get_gpio() and other
OF-specific old APIs.
No functional change intended beyond some differences in error messages.

DMA allocated buffers are a precious resource. If there is no need for
DMA allocations, then it might be worth to use non-dma allocated
buffers.
After testing the gs_usb driver with and without DMA allocation, there
does not seem to be a significant change in latency or CPU utilization
either way. Therefore, DMA allocation is not necessary and removed.
Internal buffers used within urbs were managed and freed manually.
These buffers are no longer needed to be managed by the driver. The
URB_FREE_BUFFER flag, allows for the buffers in question to be
automatically freed.

The candleLight community is working on switchable termination support
for the candleLight firmware. As the the Linux CAN framework supports
switchable termination add this feature to the gs_usb driver.
Devices supporting the feature should set the
GS_CAN_FEATURE_TERMINATION and implement the
GS_USB_BREQ_SET_TERMINATION and GS_USB_BREQ_GET_TERMINATION control
messages.
For now the driver assumes for activated termination the standard
termination value of 120Ω.

Convert the driver to use usb_control_msg_{send,recv}() instead of
usb_control_msg(). These functions allow the data to be placed on the
stack. This makes the driver a lot easier as we don't have to deal
with dynamically allocated memory.

On busy networks the CAN controller might receive CAN frames directly
after starting it but before the timecounter is setup. This will lead
to NULL pointer deref while converting the converting the CAN frame's
timestamp with the timecounter.
Close the race window by setting up the timecounter before starting
the CAN controller.

The struct timecounter::cycle_last is a 64 bit variable, read by
timecounter_cyc2time(), and written by timecounter_read(). On 32 bit
architectures this is not atomic.
Add a spinlock to protect access to struct timecounter::cycle_last. In
the gs_usb_timestamp_read() callback the lock is dropped to execute a
sleeping synchronous USB transfer. This is safe, as the variable we
want to protect is accessed during this call.

usb_control_msg_recv()
The 2nd argument of usb_control_msg_recv() is the "endpoint",
usb_control_msg_recv() will internally convert the endpoint into a
pipe with usb_rcvctrlpipe().
In gs_usb_get_timestamp() not the endpoint "0" is passed, but the
pipe. This worked by accident as endpoint is a __u8 and the lowest 8
bits of the pipe are 0. Fix this copy/paste error by using the correct
endpoint of "0".

When GEM is in SGMII mode and disabled as a wakeup source, the power
management controller can power down the entire full power domain(FPD)
if none of the FPD devices are in use.
Incase of FPD off, there are below ethernet link up issues on non-wakeup
suspend/resume. To fix it add phy_exit() in suspend and phy_init() in the
resume path which reinitializes PS GTR SGMII lanes.
$ echo +20 > /sys/class/rtc/rtc0/wakealarm
$ echo mem > /sys/power/state
After resume:
$ ifconfig eth0 up
