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".

Some BUCKs could work in single/dual phase mode, not in independent
mode. In single/dual phase mode, registers of both regulators,
must be identically set. So configure mode and value for both BUCKs.
CONF registers are not touched, leave them as default OTP settings.
PFUZE100/200 SW3A/B, could work in single/dual phase mode, so introduce
a new macro by adding a pointer to the SW3B descriptor.

Some PFUZE regulators can operate in either low or high output voltage mode,
with different minimum voltages and voltage step sizes selected by a hardware
control bit. However, the current PFUZE100 regulator driver assumes low output
voltage mode only, resulting in incorrect voltage calculation and programming
when high voltage mode is enabled.
Extend the regulator descriptor to describe high output voltage mode by adding
a mask to detect the mode and a dedicated voltage description (min_uV and
step size). Update voltage get/set handling to dynamically select the correct
voltage parameters based on the high voltage mode bit.

Depending on the phase selection (single or multi), the FPWM bits
configured forces the regulator to operate in PWM mode. In case of
multi-phase selection, the FPWM_MP bits enforce the regulator to also
operate in multi-phase. This fixes correct multi-phase operation.
While at this, correct incorrect macro alignment as well.

Peng Fan (OSS) <[email protected]> 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:

The devm alloc functions that we have may follow the Linux kernel model
where allocations are (almost always) automatically free()'d. However,
quite often we don't enable, in full U-Boot, the tracking and free()'ing
functionality. This in turn leads to memory leaks because the driver
author expects that since the functions have the same name as in the
Linux Kernel they have the same behavior. In turn we then get
functionally correct commits such as commit 00e1fed93c8c ("firmware:
ti_sci: Fix memory leaks in devm_ti_sci_get_of_resource") that manually
add these calls. Rather than manually tracking allocations and
implementing free()s, rework things so that we follow expectations by
enabling the DEVRES functionality (outside of xPL phases).
This turns DEVRES from a prompted symbol to a symbol that must be
select'd, and we now remove our non-managed alloc/free functions from
outside of xPL builds.

allow building support in XPL but rather to allow removing it which is

The helper function "ti_pd_get()" is responsible for powering on a
domain if it is powered off. In the current implementation, if a power
domain is determined to be powered off - no prior users and the PDCTL
register indicates that the user desired state is OFF, then powering on
the domain constitutes setting 'PDCTL_STATE_ON' field of the PDCTL
register.
While the current implementation indeed requests the power domain to be
transition to the ON state, the helper function "ti_pd_get()" doesn't
verify that the power domain has 'transitioned' to the ON state before
returning to its caller. As a result, it is possible that the device(s)
belonging to the power domain may be accessed before it is truly powered
on, leading to a bus abort.
Fix this by waiting for the power domain to transition to the ON state
by using "ti_pd_wait()" before returning from "ti_pd_get()".
