soc: qcom: rpmh-rsc: Ensure irqs aren't disabled by rpmh_rsc_send_data() callers

[ Upstream commit e43111f52b9ec5c2d700f89a1d61c8d10dc2d9e9 ]

Dan pointed out that Smatch is concerned about this code because it uses
spin_lock_irqsave() and then calls wait_event_lock_irq() which enables
irqs before going to sleep. The comment above the function says it
should be called with interrupts enabled, but we simply hope that's true
without really confirming that. Let's add a might_sleep() here to
confirm that interrupts and preemption aren't disabled. Once we do that,
we can change the lock to be non-saving, spin_lock_irq(), to clarify
that we don't expect irqs to be disabled. If irqs are disabled by
callers they're going to be enabled anyway in the wait_event_lock_irq()
call which would be bad.

This should make Smatch happier and find bad callers faster with the
might_sleep(). We can drop the WARN_ON() in the caller because we have
the might_sleep() now, simplifying the code.

Merge tag 'soc-drivers-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC driver updates from Arnd Bergmann:
"There are few major updates in the SoC specific drivers, mainly the
usual reworks and support for variants of the existing SoC. While this
remains Arm centric for the most part, the branch now also contains
updates to risc-v and loongarch specific code in drivers/soc/.

Notable changes include:

- Support for the newly added Qualcomm Snapdragon variants (MSM8956,
MSM8976, SM6115, SM4250, SM8150, SA8155 and SM8550) in the soc ID,
rpmh, rpm, spm and powerdomain drivers.

- Documentation for the somewhat controversial qcom,board-id
properties that are required for booting a number of machines

- A new SoC identification driver for the loongson-2 (loongarch)
platform

- memory controller updates for stm32, tegra, and renesas.

- a new DT binding to better describe LPDDR2/3/4/5 chips in the
memory controller subsystem

- Updates for Tegra specific drivers across multiple subsystems,
improving support for newer SoCs and better identification

- Minor fixes for Broadcom, Freescale, Apple, Renesas, Sifive, TI,
Mediatek and Marvell SoC drivers"

power-domain drivers. SM8550 support is added to the LLCC driver.
The AOSS QMP binding is declared compatible for SM8550.

soc: qcom: rpmh-rsc: Avoid unnecessary checks on irq-done response

The RSC interrupt is issued only after the request is complete. For
fire-n-forget requests, the irq-done interrupt is sent after issuing the
RPMH request and for response-required request, the interrupt is
triggered only after all the requests are complete.

These unnecessary checks in the interrupt handler issues AHB reads from
a critical path. Lets remove them and clean up error handling in
rpmh_request data structures.

Merge tag 'qcom-drivers-for-6.2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers

Qualcomm driver updates for 6.2

The qcom,msm-id and qcom,board-id DeviceTree properties are documented,
to allow them to be used in configurations or devices requiring these
and the socinfo driver is updated to reuse the introduced identifiers.

The rpmh-rsc driver is extended to register for PM runtime notifications
from the CPU clusters, in order to submit sleep and wake votes the last
core in a cluster is being powered down.

A mechanism for keeping rpmhpd resources voted until sync_state is
introduced, this ensures that power-domains required during boot are
kept enabled. The rpmhpd power-domains for SDM670 are also added.

Support for the new QDU1000/QRU1000 platform is introduced in the rpmhpd
and socinfo drivers.

The APR driver gains missing error handling. QMI message descriptors in
the PDR driver are made const.

Support for the RPM found in SM6375 is added. The SPM driver gains
support for MSM8939 and MSM8976 platforms.

The stats and command-db drvers are marked as not having PM support.

soc: qcom: rpmh-rsc: Write CONTROL_TCS with next timer wakeup

The next wakeup timer value needs to be set in always on domain timer
as the arch timer interrupt can not wakeup the SoC if after the deepest
CPUidle states the SoC also enters deepest low power state.

To wakeup the SoC in such scenarios the earliest wakeup time is set in
CONTROL_TCS and the firmware takes care of setting up its own timer in
always on domain with next wakeup time. The timer wakes up the RSC and
sets resources back to wake state.
