c4fb7d2eac soc: qcom: pmic_glink_altmode: fix port sanity check
The PMIC GLINK altmode driver currently supports at most two ports.

Fix the incomplete port sanity check on notifications to avoid
accessing and corrupting memory beyond the port array if we ever get a
notification for an unsupported port.

Now as the issue with the UCSI_GET_PDOS is worked around, enable UCSI

70b139a7af soc: qcom: stats: Express AOSS QMP module dependency
In the case that the Qualcomm Sleep stats driver is builtin and the AOSS
QMP driver is built as a module, neither the implementation nor the stub
functions are available during linking, resulting in the following
errors:

  qcom_stats.c:(.text+0x33c): undefined reference to `qmp_send'
  qcom_stats.c:(.text+0x8a0): undefined reference to `qmp_get'

Resolve this by expressing the dependency between the two modules.

Unguarded 64-bit division is not allowed on 32-bit kernels because this
is very slow. The result of trying anyway is a link failure:

qcom_stats.c:(.text+0x334): undefined reference to `__aeabi_uldivmod'

As this function is only used for debugging and not performance critical,
rewrite it to use div_u64() instead. ARCH_TIMER_FREQ is a multiple of
MSEC_PER_SEC anyway, so there is no loss in precisison.

385903a7ec SoC driver updates for 6.7
The highlights for the driver support this time are
 
  - Qualcomm platforms gain support for the Qualcomm Secure Execution
    Environment firmware interface to access EFI variables on certain
    devices, and new features for multiple platform and firmware drivers.
 
  - Arm FF-A firmware support gains support for v1.1 specification features,
    in particular notification and memory transaction descriptor changes.
 
  - SCMI firmware support now support v3.2 features for clock and DVFS
    configuration and a new transport for Qualcomm platforms.
 
  - Minor cleanups and bugfixes are added to pretty much all the active
    platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic,
    atmel, tegra, aspeed, vexpress, mediatek, samsung and more.
    In particular, this contains portions of the treewide conversion to
    use __counted_by annotations and the device_get_match_data helper.

ba21d6367c soc: qcom: apr: Add __counted_by for struct apr_rx_buf and use struct_size()
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time via CONFIG_UBSAN_BOUNDS (for
array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

While there, use struct_size() helper, instead of the open-coded
version, to calculate the size for the allocation of the whole
flexible structure, including of course, the flexible-array member.

This code was found with the help of Coccinelle, and audited and
fixed manually.

As it was pointed out by Simon Ser, the DRM_MODE_CONNECTOR_USB connector
is reserved for the GUD devices. Other drivers (i915, amdgpu) use
DRM_MODE_CONNECTOR_DisplayPort even if the DP stream is handled by the
USB-C altmode. While we are still working on implementing the proper way
to let userspace know that the DP is wrapped into USB-C, change
connector type to be DRM_MODE_CONNECTOR_DisplayPort.

0b742c498b soc: qcom: ocmem: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

In some configurations, the exact placement of the rmtfs shared memory
region isn't so strict. The DeviceTree author can then choose to use the
"size" property and rely on the OS for placement (in combination with
"alloc-ranges", if desired).

But on some platforms the rmtfs memory region may not be allocated
adjacent to regions allocated by other clients. Add support for
discarding the first and last 4k block in the region, if
qcom,use-guard-pages is specified in DeviceTree.

f8fd5c2483 This pull request is full of clk driver changes. In fact, there aren't any
changes to the clk framework this time around. That's probably because everyone
 was on vacation (yours truly included). We did lose a couple clk drivers this
 time around because nobody was using those devices. That skews the diffstat a
 bit, but either way, nothing looks out of the ordinary here. The usual suspects
 are chugging along adding support for more SoCs and fixing bugs.
 
 If I had to choose, I'd say the theme for the past few months has been
 "polish". There's quite a few patches that migrate to
 devm_platform_ioremap_resource() in here. And there's more than a handful of
 patches that move the NR_CLKS define from the DT binding header to the driver.
 There's even patches that migrate drivers to use clk_parent_data and clk_hw to
 describe clk tree topology. It seems that the spring (summer?) cleaning bug got
 some folks, or the semiconductor shortage finally hit the software side.
 
 New Drivers:
  - StarFive JH7110 SoC clock drivers
  - Qualcomm IPQ5018 Global Clock Controller driver
  - Versa3 clk generator to support 48KHz playback/record with audio codec on

b4f63bbff9 soc: qcom: aoss: Tidy up qmp_send() callers
With qmp_send() handling variable length messages and string formatting
he callers of qmp_send() can be cleaned up to not care about these
things.

Drop the QMP_MSG_LEN sized buffers and use the message formatting, as
appropriate.

8873d1e2f8 soc: qcom: aoss: Format string in qmp_send()
The majority of callers to qmp_send() composes the message dynamically
using some form of sprintf(), resulting in unnecessary complication and
stack usage.

By changing the interface of qmp_send() to take a format string and
arguments, the duplicated composition of the commands can be moved to a
single location.

59e0910083 soc: qcom: aoss: Move length requirements from caller
The existing implementation of qmp_send() requires the caller to provide
a buffer which is of word-aligned. The underlying reason for this is
that message ram only supports word accesses, but pushing this
requirement onto the clients results in the same boiler plate code
sprinkled in every call site.

By using a temporary buffer in qmp_send() we can hide the underlying
hardware limitations from the clients and allow them to pass their
NUL-terminates C string directly.

8d207400fd soc: qcom: qmi_encdec: Restrict string length in decode
The QMI TLV value for strings in a lot of qmi element info structures
account for null terminated strings with MAX_LEN + 1. If a string is
actually MAX_LEN + 1 length, this will cause an out of bounds access
when the NULL character is appended in decoding.
