Qualcomm driver fixes for v6.14

Fixes a locking issue in the PDR implementation, which manifest itself
as transaction timeouts during the startup procedure for some
remoteprocs.

A registration race is fixed in the custom efivars implementation,
resolving reported NULL pointer dereferences.

Error handling related to tzmem allocation is corrected, to ensure that
the allocation error is propagated.

Lastly a trivial merge mistake in pmic_glink is addressed.

2eeb03ad9f soc: qcom: pdr: Fix the potential deadlock
When some client process A call pdr_add_lookup() to add the look up for
the service and does schedule locator work, later a process B got a new
server packet indicating locator is up and call pdr_locator_new_server()
which eventually sets pdr->locator_init_complete to true which process A
sees and takes list lock and queries domain list but it will timeout due
to deadlock as the response will queued to the same qmi->wq and it is
ordered workqueue and process B is not able to complete new server
request work due to deadlock on list lock.

Fix it by removing the unnecessary list iteration as the list iteration
is already being done inside locator work, so avoid it here and just
call schedule_work() here.

       Process A                        Process B

                                     process_scheduled_works()

                                         pdr->locator_init_complete=true;
   pdr_locator_work()
    mutex_lock(&pdr->list_lock);

     pdr_locate_service()                  mutex_lock(&pdr->list_lock);

               req->service_name,
               ret);

Timeout error log due to deadlock:

"
 PDR: tms/servreg get domain list txn wait failed: -110
 PDR: service lookup for msm/adsp/sensor_pd:tms/servreg failed: -110
"

Thanks to Bjorn and Johan for letting me know that this commit also fixes
an audio regression when using the in-kernel pd-mapper as that makes it
easier to hit this race. [1]

54a2add7fb soc: qcom: Use str_enable_disable-like helpers
Replace ternary (condition ? "enable" : "disable") syntax with helpers
from string_choices.h because:
1. Simple function call with one argument is easier to read.  Ternary
   operator has three arguments and with wrapping might lead to quite
   long code.
2. Is slightly shorter thus also easier to read.
3. It brings uniformity in the text - same string.
4. Allows deduping by the linker, which results in a smaller binary
   file.

22cf4fae66 soc: qcom: socinfo: Avoid out of bounds read of serial number
On MSM8916 devices, the serial number exposed in sysfs is constant and does
not change across individual devices. It's always:

  db410c:/sys/devices/soc0$ cat serial_number
  2644893864

The firmware used on MSM8916 exposes SOCINFO_VERSION(0, 8), which does not
have support for the serial_num field in the socinfo struct. There is an
existing check to avoid exposing the serial number in that case, but it's
not correct: When checking the item_size returned by SMEM, we need to make
sure the *end* of the serial_num is within bounds, instead of comparing
with the *start* offset. The serial_number currently exposed on MSM8916
devices is just an out of bounds read of whatever comes after the socinfo
struct in SMEM.

Fix this by changing offsetof() to offsetofend(), so that the size of the
field is also taken into account.

Pull SoC driver updates from Arnd Bergmann:
 "Nothing particular important in the SoC driver updates, just the usual
  improvements to for drivers/soc and a couple of subsystems that don't
  fit anywhere else:

   - The largest set of updates is for Qualcomm SoC drivers, extending
     the set of supported features for additional SoCs in the QSEECOM,
     LLCC and socinfo drivers.a

   - The ti_sci firmware driver gains support for power managment

   - The drivers/reset subsystem sees a rework of the microchip sparx5
     and amlogic reset drivers to support additional chips, plus a few
     minor updates on other platforms

   - The SCMI firmware interface driver gains support for two protocol
     extensions, allowing more flexible use of the shared memory area
     and new DT binding properties for configurability.

   - Mediatek SoC drivers gain support for power managment on the MT8188
     SoC and a new driver for DVFS.

   - The AMD/Xilinx ZynqMP SoC drivers gain support for system reboot
     and a few bugfixes

   - The Hisilicon Kunpeng HCCS driver gains support for configuring
     lanes through sysfs

  Finally, there are cleanups and minor fixes for drivers/{soc, bus,
  memory}, including changing back the .remove_new callback to .remove,
  as well as a few other updates for freescale (powerpc) soc drivers,

A few more Qualcomm driver updates for v6.13

Make the Adreno driver invoke the SMMU aperture setup firmware function,
which is required to allow the GPU to manage per-process page tables in
some firmware versions - as an example Rb3Gen2 has no GPU without this.

Add X1E Devkit to the list of devices that has functional EFI variable
access through the uefisecapp.

Flip the "manual slice configuration quirk" in the Qualcomm LLCC driver,
as this only applies to a single platform, and introduce support for
QCS8300, QCS615, SAR2130P, and SAR1130P.

Lastly, add IPQ5424 and IPQ5404 to the Qualcomm socinfo driver.

Commit c14e64b469 ("soc: qcom: llcc: Support chipsets that can write

to firmware security policies. That turned out only to concern SDM845,
but the condition was chosen such that all other entries (for SoCs that
didnot need it) were required to set .need_llcc_cfg = true.

Flip the condition, so the default is "doesn't need the workaround".

Qualcomm driver updates for v6.13

Enable QSEECOM, and thereby access to EFI variables, for Lenovo Yoga
Slim 7x, Dell XPS 13, Microsoft Surface Pro 9.

Last Level Cache Controller (LLCC) driver code is shuffled, to improve
readability of the tables.

The Qualcomm socinfo driver gains support for QCS615, QCS9100, SAR1130P,
SAR2130P, and SA8255P.

A few drivers are simplified using dev_err_probe() and guard(), and a
few kernel-doc issues are corrected.

Mentioning of the #linux-msm IRC channel is added to the MAINTAINERS
file.

Qualcomm driver fixes for v6.12

The Qualcomm EDAC driver's configuration of interrupts is made optional,
to avoid violating security constriants on X Elite platform .

The SCM drivers' detection mechanism for the presence of SHM bridge in QTEE,
is corrected to handle the case where firmware successfully returns that
the interface isn't supported.

The GLINK driver and the PMIC GLINK interface is updated to handle
buffer allocation issues during initialization of the communication
channel.

Allocation error handling in the socinfo dirver is corrected, and then
the fix is corrected.

511c06e390 soc: Switch back to struct platform_driver::remove()
After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/soc to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

On the way do a few whitespace changes to make indention consistent.

f8c8791924 soc: qcom: pmic_glink: Handle GLINK intent allocation rejections
Some versions of the pmic_glink firmware does not allow dynamic GLINK
intent allocations, attempting to send a message before the firmware has
allocated its receive buffers and announced these intent allocations
will fail. When this happens something like this showns up in the log:

    pmic_glink_altmode.pmic_glink_altmode pmic_glink.altmode.0: failed to send altmode request: 0x10 (-125)
    pmic_glink_altmode.pmic_glink_altmode pmic_glink.altmode.0: failed to request altmode notifications: -125
    ucsi_glink.pmic_glink_ucsi pmic_glink.ucsi.0: failed to send UCSI read request: -125
    qcom_battmgr.pmic_glink_power_supply pmic_glink.power-supply.0: failed to request power notifications

GLINK has been updated to distinguish between the cases where the remote
is going down (-ECANCELED) and the intent allocation being rejected
(-EAGAIN).

Retry the send until intent buffers becomes available, or an actual
error occur.

To avoid infinitely waiting for the firmware in the event that this
misbehaves and no intents arrive, an arbitrary 5 second timeout is
used.

This patch was developed with input from Chris Lew.
