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.

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.

dt-bindings: arm: mediatek: mmsys: change compatible for MT8195

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.

PM: domains: Store the next hrtimer wakeup in genpd

The arch timer cannot wake up the Qualcomm Technologies, Inc. (QTI) SoCs
from the deeper CPUidle states. To be able to wakeup from these deeper
states, another always-on timer needs to be programmed through the so
called CONTROL_TCS.

As the RSC is part of CPU subsystem and the corresponding APSS RSC device
is attached to the cluster PM domain (through genpd), it holds the
responsibility to program the always-on timer, before entering any of these
deeper CPUidle states.

However, programming the timer requires information about the next hrtimer
wakeup for the cluster PM domain, which is currently only known by genpd.
Therefore, let's share this data through a new genpd helper function,
dev_pm_genpd_get_next_hrtimer().

Merge tag 'memory-controller-drv-6.2' of https://git./linux/kernel/git/krzk/linux-mem-ctrl into arm/drivers

Memory controller drivers for v6.2

1. STM32 FMC2:
   a. Correct in bindings the name of property for address
      setup duration. The DTS and driver were already using proper name,
      so it is only alignment of bindings with real usage.
   b. Split off STM32 memory controller bus peripheral properties into
      generic ones (re-usable by multiple memory controllers) and STM32 bus
      peripheral.  This way, the FMC2 controller properties in Micrel
      KSZ8851MLL ethernet controller node can be properly validated.

2. Tegra MC: simplify with DEFINE_SHOW_ATTRIBUTE.

3. Renesas RPC IF: add suppor tfor R-Car Gen4.

4. LPDDR bindings: refactor and extend with description of DDR channels.
   Add also bindings for LPDDR4 and LPDDR5.

The rationale for (4) above - LPDDR bindings changes, wrote by Julius Werner:

"We (Chromium OS) have been trying to find a way to pass LPDDR memory
chip information that is available to the firmware through the FDT
(mostly for userspace informational purposes, for now). We have been
using and expanding the existing "jedec,lpddr2" and "jedec,lpddr3"
bindings for this (e.g. [1]). The goal is to be able to identify the
memory layout of the system (how the parts look like, how they're tied
together, how much capacity there is in total) as accurately as
possible from software-probed values.

...

The problem with this is that each individual LPDDR chip has its own
set of mode registers (per rank) that only describe the density of
that particular chip (rank). The host memory controller may have
multiple channels (each of which is basically an entirely separate set
of physical LPDDR pins on the board), a single channel may be
connected to multiple LPDDR chips (e.g. if the memory controller has
an outgoing 32-bit channel, that channel could be tied to two 16-bit
LPDDR chips by tying the low 16 bits to one and the high 16 bits to
the other), and then each of those chips may offer multiple
independent ranks (which rank is being accessed at a given time is
controlled by a separate chip select pin).

So if we just have one "io-width" and one "density" field in the FDT,
there's no way to figure out how much memory there's actually
connected in total, because that only describes a single LPDDR chip.
Worse, there may be chips where different ranks have different
densities (e.g. a 6GB dual-rank chip with one 4GB and one 2GB rank),
and different channels could theoretically be connected to chips of
completely different manufacturers."

soc: fsl: qe: Avoid using gpio_to_desc()

The qe gpio driver is a custom API combined GPIO and pin control
driver that exist outside of the pin control subsystem for historical
reasons.

We want to get rid of the old GPIO numberspace, so instead of
calling gpio_to_desc() we get the gpio descriptor for the requested
line from the device tree directly without passing through the
GPIO numberspace, and then we get the gpiochip from the descriptor.

Using the reference counting inside the gpio descriptor we can drop
the reference counting code in this driver. A second gpiod_get()
will not succeed.

To obtain the local hardware offset of the GPIO line, the driver
need to include the header from the gpiolib internals. This isn't
pretty but it is the lesser evil compared to keeping the code
as a roadblock to gpiolib refactoring. A proper solution would be
to rewrite the driver as a real pin control driver with a
built-in gpio_chip.
