Convert the LPASS LPI pinctrl driver to use the PM clock framework for
runtime power management.
This allows the LPASS LPI pinctrl driver to drop clock votes when idle,
improves power efficiency on platforms using LPASS LPI island mode, and
aligns the driver with common runtime PM patterns used across Qualcomm
LPASS subsystems.
Guard GPIO register read/write helpers and slew-rate register programming
with synchronous runtime PM calls so the device is active during MMIO
operations whenever autosuspend is enabled.
Make PINCTRL_LPASS_LPI depend on PM_CLK, since this patch introduces
direct PM clock API use in the shared core.

The main SoC TLMM (Top-Level Multiplexer) pin controller drivers are
essential for booting up SoCs and are not really optional for a given
platform. Kernel should not ask users choice of drivers when that
choice is obvious and known to the developers that answer should be
'yes' or 'module'.
Switch all Qualcomm TLMM pin controller drivers to a default 'yes' for
ARCH_QCOM. This has impact:
1. arm64 defconfig: enable PINCTRL_SM7150, PINCTRL_IPQ9650 and
PINCTRL_HAWI, which were not selected before but should be, because
these platforms need them for proper boot.
2. arm qcom_defconfig: no changes.
3. arm multi_v7 defconfig: enable drivers necessary to boot ARM 32-bit
platforms, which are already enabled on qcom_defconfig.
4. COMPILE_TEST builds: enable by default all drivers for arm or arm64
builds, whenever ARCH_QCOM is selected. This has impact on build
time and feels logical, because if one selects ARCH_QCOM then
probably by default wants to build test it entirely. Kernels with
COMPILE_TEST are not supposed to be used for booting.

Qualcomm SC7280 and SM8350 SoCs have slightly different LPASS audio
blocks (v9.4.5 and v9.2), however the LPASS LPI pin controllers are
exactly the same. The driver for SM8350 has two issues, which can be
fixed by simply moving over to SC7280 driver which has them correct:
1. "i2s2_data_groups" listed twice GPIO12, but should have both GPIO12
and GPIO13,
2. "swr_tx_data_groups" contained GPIO5 for "swr_tx_data2" function, but
that function is also available on GPIO14, thus listing it twice is
not necessary. OTOH, GPIO5 has also "swr_rx_data1", so selecting
swr_rx_data function should not block the TX one.

Now that SCM can be a loadable module, we have to add another
dependency to avoid link failures when ipa or adreno-gpu are
built-in:
aarch64-linux-ld: drivers/net/ipa/ipa_main.o: in function `ipa_probe':
ipa_main.c:(.text+0xfc4): undefined reference to `qcom_scm_is_available'
ld.lld: error: undefined symbol: qcom_scm_is_available
>>> referenced by adreno_gpu.c
>>> gpu/drm/msm/adreno/adreno_gpu.o:(adreno_zap_shader_load) in archive drivers/built-in.a
This can happen when CONFIG_ARCH_QCOM is disabled and we don't select
QCOM_MDT_LOADER, but some other module selects QCOM_SCM. Ideally we'd
use a similar dependency here to what we have for QCOM_RPROC_COMMON,
but that causes dependency loops from other things selecting QCOM_SCM.
This appears to be an endless problem, so try something different this
time:
- CONFIG_QCOM_SCM becomes a hidden symbol that nothing 'depends on'
but that is simply selected by all of its users
- All the stubs in include/linux/qcom_scm.h can go away
- arm-smccc.h needs to provide a stub for __arm_smccc_smc() to
allow compile-testing QCOM_SCM on all architectures.
- To avoid a circular dependency chain involving RESET_CONTROLLER
and PINCTRL_SUNXI, drop the 'select RESET_CONTROLLER' statement.
According to my testing this still builds fine, and the QCOM
platform selects this symbol already.

no core changes at all this time, just driver work!
New drivers:
- New subdriver for Intel Keem Bay (an ARM-based SoC)
- New subdriver for Qualcomm MDM9607 and SM6115
- New subdriver for ST Microelectronics STM32MP135
- New subdriver for Freescale i.MX8ULP ("Ultra Low Power")
- New subdriver for Ingenic X2100
- Support for Qualcomm PMC8180, PMC8180C, SA8155p-adp PMIC GPIO
- Support Samsung Exynos850
- Support Renesas RZ/G2L
Enhancements:
- A major refactoring of the Rockchip driver, breaking part of it out
to a separate GPIO driver in drivers/gpio
- Pin bias support on Renesas r8a77995
- Add SCI pins support to Ingenic JZ4755 and JZ4760
- Mediatek device tree bindings converted to YAML
