This old patch was marked as deferred. Bring it back to life, to continue
towards the removal of common.h
Move this out of the common header and include it only where needed.

The behaviour of dev_read_addr_size() is surprising as it does not
handle #address-cells and #size-cells but instead hardcodes the values
based on sizeof(fdt_addr_t).
This is different from dev_read_addr_size_index() and
dev_read_addr_size_name() both of which do read the cell sizes from the
device tree.
Since dev_read_addr_size() is only used by a single driver and this
driver is broken when CONFIG_FDT_64BIT does not match the address size
in the device tree, fix the function to behave like all of the other
similarly named functions. Drop the property name argument as the only
caller passes "reg" and this is the expected property name matching the
other similarly named functions.

The current DT bindings for the rk3588 clock use a different ID than the
one that is supposed to be written to the hardware registers.
Thus, we cannot use directly the id provided in the phandle, but rather
use a lookup table to correctly setup the hardware.
This approach has been implemented already in Linux, by commit :
f1c506d152ff ("clk: rockchip: add clock controller for the RK3588")
Hence, implement a similar approach using the lookup table, and adapt
the existing reset driver to work with SoCs using lookup table.
The file rst-rk3588.c has been copied as much as possible from Linux.
Adapt the clk rk3588 driver as well to bind the reset driver with the
lookup table.

Add a DM reset driver for StarFive JH7110 SoC.
Note that the register base address of reset controller is the

tree node alone for reset driver.It binds device node in

Add reset control support in USB glue logic. This needs to control
the external clocks and resets for the logic before accessing the
glue logic.
The USB dm tree when using dwc3-generic is the following:
USB glue
+-- controller (need controller-reset)
+-- controller-reset (need syscon-reset)
+-- phy
The controller needs to deassert "controller-reset" in USB glue before
the controller registers are accessed. The glue needs to deassert
"syscon-reset" before the glue registers are accessed.
The glue itself doesn't have "syscon-reset", so the controller-reset
controls "syscon-reset" instead.

Add support for at91 reset controller's basic assert/deassert
operations. Since this driver conflicts with the
SYSRESET driver because they both bind to the same RSTC node,
implement a custom bind hook that would manually bind the
sysreset driver, if enabled, to the same RSTC DT node.
Furthermore, delete the no longer needed compatibles from the
SYSRESET driver and rename it to make sure than any possible
conflicts are avoided.

Changes SCMI driver API function devm_scmi_process_msg() to add
an SCMI channel reference argument for when SCMI agent supports
SCMI protocol specific channels. First argument of devm_scmi_process_msg()
is also change to point to the caller SCMI protocol device rather
than its parent device (the SCMI agent device).
The argument is a pointer to opaque struct scmi_channel known from
the SCMI transport drivers. It is currently unused and caller a pass
NULL value. A later change will enable such support once SCMI protocol
drivers have means to get the channel reference during initialization.

Changes devm_scmi_process_msg() first argument from target parent device
to current SCMI device and lookup the SCMI agent device among SCMI device
parents for find the SCMI agent operator needed for communication with
the firmware.
This change is needed in order to support CCF in clk_scmi driver unless
what CCF will fail to find the right udevice related to exposed SCMI
clocks.
This patch allows to simplify the caller sequence, using SCMI device
reference as parameter instead of knowing SCMI uclass topology. This
change also adds some protection in case devm_scmi_process_msg() API
function is called for an invalid device type.

This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.
Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.
