One more Qualcomm driver update for 6.3
This introduces the power-supply driver providing battery and power
supply status on many recent Qualcomm platforms, including the Qualcomm
SC8180X and SC8280XP laptop platforms and the SM8350 mobile platform.
It's introduced through the Qualcomm tree due to its dependencies on the
pmic_glink driver, which was merged already for v6.3.

power: supply: Introduce Qualcomm PMIC GLINK power supply
The PMIC GLINK service, running on a coprocessor of modern Qualcomm
platforms, deals with battery charging and fuel gauging, as well as
reporting status of AC and wireless power supplies.
As this is just one of the functionalities provided by the PMIC GLINK
service, this power supply driver is implemented as an auxilirary bus
driver, spawned by the main "pmic glink" driver when the PMIC GLINK
service is detected.

soc: apple: rtkit: Do not copy the reg state structure to the stack
The register state struct is 848 bytes, which ends up bloating the
apple_rtkit_crashlog_dump_regs stack frame beyond 1024 on some
32-bit platforms, triggering compile warnings.
This doesn't matter for 64BIT/ARM64, but there's also no good reason to
copy the structure to the stack in this case. We can use __packed to
avoid alignment issues, there are no double-read hazards, and this is a
fatal error path so performance does not matter.

This introduces a new driver for the Data Capture and Compare block,
which provides a mechanism for capturing hardware state (access MMIO
registers) either upon request of triggered automatically e.g. upon a
watchdog bite, for post mortem analysis.
The remote filesystem memory share driver gains support for having its
memory bound to more than a single VMID.
The SCM driver gains the minimal support needed to support a new
mechanism where secure world can put calls on hold and later request
them to be retried.
Support for the new SA8775P platform is added to rpmhpd, QDU1000 is
added to the SCM driver and a long list of platforms are added to the
socinfo driver. Support for socinfo data revision 16 is also introduced.
Lastly a driver to program the ramp controller in MSM8976 is introduced.

memory: renesas-rpc-if: Remove redundant division of dummy
The dummy cycles value was wrongly calculated if dummy.buswidth > 1,
which affects QSPI, OSPI, HyperFlash on various SoCs. We're lucky in
Single SPI case since its dummy.buswidth equals to 1, so the result of
the division is unchanged
This issue can be reproduced using something like the following commands
A. QSPI mode: Mount device with jffs2 format
jffs2: CLEANMARKER node found at 0x00000004, not first node in block (0x00000000)
B. QSPI mode: Write data to mtd10, where mtd10 is a parition on SPI Flash
storage, defined properly in a device tree
[Correct fragment, read from SPI Flash]
root@v3x:~# echo "hello" > /dev/mtd10
root@v3x:~# hexdump -C -n100 /dev/mtd10
00000000 68 65 6c 6c 6f 0a ff ff ff ff ff ff ff ff ff ff |hello...........|
00000010 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................|
[Incorrect read of the same fragment: see the difference at offsets 0-3]
root@v3x:~# echo "hello" > /dev/mtd10
root@v3x:~# hexdump -C -n100 /dev/mtd10
00000000 00 00 00 00 68 65 6c 6c 6f 0a ff ff ff ff ff ff |....hello.......|
00000010 ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff |................|
As seen from the result, 4 NULL bytes were inserted before the test data.
Wrong calculation in rpcif_prepare() led to miss of some dummy cycle. A
division by bus width is redundant because it had been performed already
in spi-rpc-if.c::rpcif_spi_mem_prepare()
Fix this by removing the redundant division.

soc: qcom: stats: Populate all subsystem debugfs files
This driver relies on SMEM to populate items for each subsystem before
the device probes. The items in SMEM that are being looked for are
populated by the subsystems lazily, and therefore may not exist until
the device has booted. For example, if I build this driver into the
kernel on Trogdor Lazor and boot up, I don't see a 'modem' debugfs file
populated, because the modem boots and populates the SMEM item after
this driver probes.
Always populate the files for the subsystems if they're in SMEM, and
make the qcom_subsystem_sleep_stats_show() function return 0 if the SMEM
items still isn't there. This way we can run a simple command like
grep ^ /sys/kernel/debug/qcom_stats/*
and collect the subsystem sleep stats without interspersed errors or
missing details entirely because this driver probed first.

soc: qcom: pmic_glink: Introduce altmode support
With the PMIC GLINK service, the host OS subscribes to USB-C altmode
messages, which are sent by the firmware to notify the host OS about
state updates and HPD interrupts.
The pmic_glink_altmode driver registers for these notifications and
propagates the notifications as typec_mux, typec_switch and DRM OOB
notifications as necessary to implement DisplayPort altmode support.

The PMIC GLINK service runs on one of the co-processors of some modern
Qualcomm platforms and implements USB-C and battery managements. It uses
a message based protocol over GLINK for communication with the OS, hence
the name.
The driver implemented provides the rpmsg device for communication and
uses auxiliary bus to spawn off individual devices in respective
subsystem. The auxiliary devices are spawned off from a
platform_device, so that the drm_bridge is available early, to allow the
DisplayPort driver to probe even before the remoteproc has spun up.

Merge tag 'scmi-updates-6.3' of git://git./linux/kernel/git/sudeep.holla/linux into soc/drivers
Arm SCMI updates for v6.3
The main addition is a unified userspace interface for SCMI irrespective
of the underlying transport and along with some changed to refactor the
SCMI stack probing sequence.
1. SCMI unified userspace interface
This is to have a unified way of testing an SCMI platform firmware
implementation for compliance, fuzzing etc., from the perspective of
the non-secure OSPM irrespective of the underlying transport supporting
SCMI. It is just for testing/development and not a feature intended fo
use in production.
Currently an SCMI Compliance Suite[1] can only work by injecting SCMI
messages using the mailbox test driver only which makes it transport
specific and can't be used with any other transport like virtio,
smc/hvc, optee, etc. Also the shared memory can be transport specific
and it is better to even abstract/hide those details while providing
the userspace access. So in order to scale with any transport, we need
a unified interface for the same.
In order to achieve that, SCMI "raw mode support" is being added through
debugfs which is more configurable as well. A userspace application
can inject bare SCMI binary messages into the SCMI core stack; such
messages will be routed by the SCMI regular kernel stack to the backend
platform firmware using the configured transport transparently. This
eliminates the to know about the specific underlying transport
internals that will be taken care of by the SCMI core stack itself.
Further no additional changes needed in the device tree like in the
mailbox-test driver.
[1] https://gitlab.arm.com/tests/scmi-tests
2. Refactoring of the SCMI stack probing sequence
On some platforms, SCMI transport can be provide by OPTEE/TEE which
introduces certain dependency in the probe ordering. In order to address
the same, the SCMI bus is split into its own module which continues to
be initialized at subsys_initcall, while the SCMI core stack, including
its various transport backends (like optee, mailbox, virtio, smc), is
now moved into a separate module at module_init level.
This allows the other possibly dependent subsystems to register and/or
access SCMI bus well before the core SCMI stack and its dependent
transport backends.

memory: renesas-rpc-if: Split-off private data from struct rpcif
The rpcif structure is used as a common data structure, shared by the
RPC-IF core driver and by the HyperBus and SPI child drivers.
This poses several problems:
- Most structure members describe private core driver state, which
should not be accessible by the child drivers,
- The structure's lifetime is controlled by the child drivers,
complicating use by the core driver.
Fix this by moving the private core driver state to its own structure,
managed by the RPC-IF core driver, and store it in the core driver's
private data field. This requires absorbing the child's platform
device, as that was stored in the driver's private data field before.
