Add Renesas R-Car R8A78000 X5H MDLC power domain and reset driver,
which serves as a remap driver between DT power domain and reset IDs
and SCMI power domain and reset IDs in case U-Boot runs on Cortex-A,
and as a direct hardware access driver for RSIP.

The R-Car X5H SCP firmware uses different SCMI power domain and
reset IDs in different versions of the SCP firmware, which makes
this remapping necessary. The SCMI base protocol version is updated
for each new SCP firmware version, it is therefore possible to
determine which SCP firmware version is running on the platform
from the base protocol and then determine which remapping table to
use for DT power domain and reset ID to SCMI power domain and reset
ID remapping.

Currently supported versions are SCP 4.28, 4.31, 4.32 .

The DT power domain and reset ID to SCMI power domain and reset ID
remap and call mechanism is simple. Unlike SCMI clock protocol driver,
the SCMI reset and power domain protocol drivers register only a single
device. This driver looks up that single device, obtains its reset or
power domain ops, sets up struct reset_ctl or struct power_domain with
remapped SCMI ID, and invokes operations directly on the device.

In case of RSIP, all power domains are already enabled by BootROM or
early SoC initialization code, the driver therefore only acts as a
stub for the power domain part. The reset part operates as a direct
hardware access reset driver.

After discussion with the devicetree maintainers we agreed to not extend
lists with the generic compatible "apple,pmgr-pwrstate" anymore [1]. Use
"apple,t8103-pmgr-pwrstate" as base compatible as it is the SoC driver
and bindings were originally written for.
The t602x (M2 Pro/Max/Ultra) devicetrees submitted in [2] use this
compatible as fallback instead of "apple,pmgr-pwrstate".

Update dev_power_domain_ctrl() to log a warning if the power-domain
driver is not found (-ENODEV). Return 0 in this case to allow continued
execution, while preserving error handling for other failures.

Added support for Qualcomm RPMH power domain driver, responsible
for managing power domains on Qualcomm SoCs. This is a port of
the Linux RPMHPD driver [1] and sa8775p related changes. The
power domain driver currently has support to power on and off
MMCX power domain of sa8775p; support for other soc entries power
domains are stubbed, in future, the required soc support can be
added.

Prepare v2026.04-rc4

Similar to pinctrl_select_state(), add dev_has_ofnode() check before doing the
real work. Device(scmi_base.0) does not have a real device node, ofnode_null()
is assigned as the device tree node for scmi base protocol device:
'commit 7eb4eb541c14 ("firmware: scmi: install base protocol to SCMI agent")'

However with recent update in
'commit 0535e46d55d7 ("scripts/dtc: Update to upstream version v1.7.2-35-g52f07dcca47c")',
SPL panic in fdt_check_node_offset_()->fdt_next_tag(), because offset is -1
and SPL_OF_LIBFDT_ASSUME_MASK is 0xFF.

So need to validate device tree node.

Peng Fan (OSS) <peng.fan@oss.nxp.com> says:

This patch set primarily removes unused DECLARE_GLOBAL_DATA_PTR
instances.

Many files declare DECLARE_GLOBAL_DATA_PTR and include
asm/global_data.h even though gd is never used. In these cases,
asm/global_data.h is effectively treated as a proxy header, which is
not a good practice.

Following the Include What You Use principle, files should include
only the headers they actually depend on, rather than relying on
global_data.h indirectly. This approach is also adopted in Linux kernel
[1].

The first few patches are prepartion to avoid building break after
remove the including of global_data.h.

A script is for filtering the files:
list=`find . -name "*.[ch]"`
for source in ${list}
do
        result=`sed -n '/DECLARE_GLOBAL_DATA_PTR/p' ${source}`
        if [ "${result}" == "DECLARE_GLOBAL_DATA_PTR;" ]; then
                echo "Found in ${source}"

                result=`sed -n '/\<gd\>/p' ${source}`
                result2=`sed -n '/\<gd_/p' ${source}`
                result3=`sed -n '/\<gd->/p' ${source}`
                if [ "${result}" == "" ] && [ "${result2}" == "" ] && [ "${result3}" == "" ];then
                        echo "Cleanup ${source}"
                        sed -i '/DECLARE_GLOBAL_DATA_PTR/{N;/\n[[:space:]]*$/d;s/.*\n//;}' ${source}
                        sed -i '/DECLARE_GLOBAL_DATA_PTR/d' ${source}
                        sed -i '/global_data.h/d' ${source}
                        git add ${source}
                fi
        fi

Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and
drop the unnecessary inclusion of asm/global_data.h.

Headers should be included directly by the files that need them,
rather than indirectly via global_data.h.

Upstream DT uses simple-pm-bus instead of simple-bus. simple-pm-bus
requires power domain support. On am33xx, PRM manages power domains but
all domains are enabled at boot. Add stub driver with custom of_xlate
that expects no argumetns to allow simple-pm-bus and dependent devices
to probe.
