Qualcomm fix for 5.12

This bypasses the, recently introduced, interconnect handling in the
GENI (serial engine) driver when running off ACPI, as this causes the
GENI probe to fail and the Lenovo Yoga C630 to boot without keyboard and
touchpad.

soc: qcom-geni-se: Cleanup the code to remove proxy votes

2021-03-26T14:16:05+00:00

This reverts commit 048eb908a1f2 ("soc: qcom-geni-se: Add interconnect
support to fix earlycon crash")

ICC core and platforms drivers supports sync_state feature, which
ensures that the default ICC BW votes from the bootloader is not
removed until all it's consumers are probes.

The proxy votes were needed in case other QUP child drivers
I2C, SPI probes before UART, they can turn off the QUP-CORE clock
which is shared resources for all QUP driver, this causes unclocked
access to HW from earlycon.

Given above support from ICC there is no longer need to maintain
proxy votes on QUP-CORE ICC node from QUP wrapper driver for early
console usecase, the default votes won't be removed until real
console is probed.

soc: qcom: geni: shield geni_icc_get() for ACPI boot

2021-03-12T02:22:05+00:00

Currently, GENI devices like i2c-qcom-geni fails to probe in ACPI boot,
if interconnect support is enabled.  That's because interconnect driver
only supports DT right now.  As interconnect is not necessarily required
for basic function of GENI devices, let's shield geni_icc_get() call,
and then all other ICC calls become nop due to NULL icc_path, so that
GENI devices keep working for ACPI boot.

soc: qcom: ocmem: don't return NULL in of_get_ocmem

2021-02-02T21:39:13+00:00

If ocmem probe fails for whatever reason, of_get_ocmem returned NULL.
Without this, users must check for both NULL and IS_ERR on the returned
pointer - which didn't happen in drivers/gpu/drm/msm/adreno/adreno_gpu.c
leading to a NULL pointer dereference.

Remove extra le32_to_cpu() conversion, data is already converted from
le32 to cpu endianness. This fixes two following warnings:

drivers: soc: qcom: rpmpd: Add msm8994 RPM Power Domains

2021-01-25T18:37:43+00:00

MSM8994 uses similar to MSM8996, legacy-style voltage
control, but does not include a VDD_SC_CX line.

This setup is also correct for MSM8992.

Do note that there exist some boards that use a tertiary PMIC
(most likely pm8004), where SMPB on VDDGFX becomes SMPC. I
cannot test this configuration though.
