Merge series from Detlev Casanova <detlev.casanova@collabora.com>:
Add the rk3576-armsom-sige5 device tree as well as its rk3576.dtsi base
and pinctrl information in rk3576-pinctrl.dtsi.
The other commits add DT bindings documentation for the devices that
already work with the current corresponding drivers.
Note that as is, the rockchip gpio driver needs the gpio nodes
to be children of the pinctrl node, even though this is deprecated.
When the driver supports it, they can be moved out of the pinctrl node.
The power-domain@RK3576_PD_USB is a child of power-domain@RK3576_PD_VOP.
That looks strange but it is how the hardware is, and confirmed by
Rockchip: The NOC bus of USB passes through the PD of VOP, so it relies on
VOP PD.
The other bindings have been applied on next.
Changes since v3:
- Dropped mmc dt-bindings (submitted in [2])
- Dropped syscon dt-bindings (applied in [3])
- Fix gpu interrupt names mapping
- (Fix email headers overwriting)
Changes since v2:
- Fix LEDs in armsom dts
- mmc: Move allOf after the required block
- Remove saradc dt-binding commit (already applied)
- Remove opp-microvolt-L* fields
- Reword mali commit message
- Use rgmii-id and remove delays on gmac nodes
Changes since v1:
- Add eMMC support
- Add gpu node
- Add rtc node
- Add spi compatible dt-bindings
- Add watchdog support
- Dropped timer compatible commit (applied in [0])
- Move ethernet aliases to board dt
- Move mmio nodes to soc node
- Removed cru grf phandle
- Removed gpio aliases

- Removed pinctrl php-grf phandle
- Removed v2-tuning for sdcard
- Renamed clock nodes
- Renamed regulators do match regulator-vcc-<voltage>-<name>

Replace SET_RUNTIME_PM_OPS()/SET SYSTEM_SLEEP_PM_OPS() with their modern
RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() alternatives.
The combined usage of pm_ptr() and RUNTIME_PM_OPS/SYSTEM_SLEEP_PM_OPS()
allows the compiler to evaluate if the runtime suspend/resume() functions
are used at build time or are simply dead code.
This allows removing the __maybe_unused annotations from the
suspend/resume() functions.

Commit 8a0ec8c2d7 ("spi: Insert the missing pci_dev_put()before
return") added two uses of pci_dev_put() with an uninitialized dma_dev,
resulting in the following compiler warnings (or errors with
CONFIG_WERROR) when building with clang:
drivers/spi/spi-pxa2xx-pci.c:150:15: error: variable 'dma_dev' is uninitialized when used here [-Werror,-Wuninitialized]
150 | pci_dev_put(dma_dev);

228 | pci_dev_put(dma_dev);

Commit 609d7ffdc4 ("spi: pxa2xx-pci: Balance reference count for PCI
DMA device") added a call to pci_dev_put() via
devm_add_action_or_reset() in case of failures, so the recent change was
incorrect for multiple reasons. Revert it altogether.

In order to avoid blocking for an excessive amount of time, eventually
impacting on system responsiveness, interrupt handlers should finish
executing in as little time as possible.
Use threaded interrupt and move the SPI transfer handling (both
CPU and DMA) for the non-spimem case to an interrupt thread instead.
For SPI-MEM (IPM) controllers, handling is kept in the blocking
interrupt as it simply consists in signalling completion.
