The BPMP firmware driver never worked on big-endian kernels, and
cannot easily be made portable. Add a dependency to make this clear
in case anyone ever wants to try a big-endian kernel on this hardware.

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.

For previous MediaTek SoCs, such as MT8173, there are 2 display HW
pipelines binding to 1 mmsys with the same power domain, the same
clock driver and the same mediatek-drm driver.

For MT8195, VDOSYS0 and VDOSYS1 are 2 display HW pipelines binding to
2 different power domains, different clock drivers and different
mediatek-drm drivers.

Moreover, Hardware pipeline of VDOSYS0 has these components: COLOR,
CCORR, AAL, GAMMA, DITHER. They are related to the PQ (Picture Quality)
and they makes VDOSYS0 supports PQ function while they are not
including in VDOSYS1.

Hardware pipeline of VDOSYS1 has the component ETHDR (HDR related
component). It makes VDOSYS1 supports the HDR function while it's not
including in VDOSYS0.

To summarize0:
Only VDOSYS0 can support PQ adjustment.
Only VDOSYS1 can support HDR adjustment.

Therefore, we need to separate these two different mmsys hardwares to
2 different compatibles for MT8195.
