This is the first half of the driver changes:
- A treewide interface change to the "syscore" operations for
power management, as a preparation for future Tegra specific
changes.
- Reset controller updates with added drivers for LAN969x, eic770
and RZ/G3S SoCs.
- Protection of system controller registers on Renesas and Google SoCs,
to prevent trivially triggering a system crash from e.g. debugfs
access.
- soc_device identification updates on Nvidia, Exynos and Mediatek
- debugfs support in the ST STM32 firewall driver
- Minor updates for SoC drivers on AMD/Xilinx, Renesas, Allwinner, TI
- Cleanups for memory controller support on Nvidia and Renesas

Commit a52ddb98a6 ("memory: tegra186-emc: Simplify and handle deferred
probe with dev_err_probe()") accidently dropped a call to 'put_bpmp' to
release a handle to the BPMP when getting the EMC clock fails. Fix this
by restoring the 'goto put_bpmp' if devm_clk_get() fails.

2. Decode the calltraces a bit easier,

Add support to enable Memory Controller (MC) and External Memory
Controller (EMC) drivers for Tegra264. The nodes for MC and EMC are
mostly the same as Tegra234 but differ in number of channels and
interrupt numbers.
The patch also adds the bandwidth manager definitions required for
Tegra264 and uses them to populate the memory client table. All of
these are needed to properly enable memory interconnect (ICC) support.

This bulk of the changes in this release are driver work, as well as
new device support we have some important work on performance over
several drivers, and big overhauls for maintainability on a couple too.
Highlights include:
- Big cleanups of the sh-msiof driver from Geert Uytterhoeven, and of
the NXP FSPI driver from Haibo Chen.
- Performance improvements for the AXI SPI engine.
- Support for writes to memory mapped flashes on Renesas devices.
- Integrated DMA support for Tegra210 QSPI, used by the Tegra234.
- DMA support for Amlogic SPI controllers.
- Support for AMD HID2, Qualcomm IPQ5018, Renesas RZ/G3E, Rockchip
RK3528 and Samsung Exynos Autov920.
An update to fix some issues with the Atmel QSPI driver runtime PM
pulled in a new API from the PM core, and the Renesas memory mapped
write changes pull in some code that's shared in drivers/memory.

Memory controller drivers for v6.16, part two
Few fixes for STM32 Octo Memory Manager driver introduced for the same
cycle in few commits before. These fixes were reported only after wider
coverage by bots through linux-next exposure.

irq_domain_add_linear() is going away as being obsolete now. Switch to
the preferred irq_domain_create_linear(). That differs in the first
parameter: It takes more generic struct fwnode_handle instead of struct
device_node. Therefore, of_fwnode_handle() is added around the
parameter.
Note some of the users can likely use dev->fwnode directly instead of
indirect of_fwnode_handle(dev->of_node). But dev->fwnode is not
guaranteed to be set for all, so this has to be investigated on case to
case basis (by people who can actually test with the HW).

There are two error handling bugs in the stm32_omm_configure() function.
1) The error code needs to be set if clk_get_rate() fails.
2) If devm_reset_control_get_exclusive() then call
pm_runtime_put_sync_suspend() before returning.

Octo Memory Manager driver (OMM) manages:
- the muxing between 2 OSPI busses and 2 output ports.
There are 4 possible muxing configurations:
- direct mode (no multiplexing): OSPI1 output is on port 1 and OSPI2
output is on port 2
- OSPI1 and OSPI2 are multiplexed over the same output port 1
- swapped mode (no multiplexing), OSPI1 output is on port 2,
OSPI2 output is on port 1
- OSPI1 and OSPI2 are multiplexed over the same output port 2
- the split of the memory area shared between the 2 OSPI instances.
- chip select selection override.
- the time between 2 transactions in multiplexed mode.
- check firewall access.

pointers and data to handle the differences between xspi and rpc-if

Even though XSPI and RPCIF has different register layout, reuse the code
by adding wrapper functions to support both XSPI and RPC-IF.
While at it, replace error check for pm_runtime_resume_and_get().
