New drivers:
- Last merge window we created a driver for the Ralink RT2880.
We are now moving the Ralink SoC pin control drivers out of the MIPS
architecture code and into the pin control subsystem. This concerns
RT288X, MT7620, RT305X, RT3883 and MT7621.
- Qualcomm SM6125 SoC pin control driver.
- Qualcomm spmi-gpio support for PM7325.
- Qualcomm spmi-mpp also handles PMI8994 (just a compatible string)
- Mediatek MT8365 SoC pin controller.
- New device HID for the AMD GPIO controller.
Improvements:
- Pin bias config support for a slew of Renesas pin controllers.
- Incremental improvements and non-urgent bug fixes to the Renesas
SoC drivers.
- Implement irq_set_wake on the AMD pin controller so we can wake
up from external pin events.
Misc:
- Devicetree bindings for the Apple M1 pin controller, we will probably
see a proper driver for this soon as well.

Pull pin control updates from Linus Walleij:
"This is the bulk of pin control changes for the v5.14 kernel. Not so
much going on. No core changes, just drivers.

pin controller.

AST2600 has two USB ports, A, B:
Port A supports 4 distinct modes:

2. Hub to PHY
3. BMC EHCI to PHY
4. PCIe EHCI to PHY
Port B support 3 modes:
1. USB1.1 HID controller
2. USB2.0 Device controller
3. BMC EHCI port2
Implement pinmux support by mapping each ports' functions onto a single
pin group for each port.

Early revisions of the AST2600 datasheet are conflicted about the state
of the LPC/eSPI strapping bit (SCU510[6]). Conversations with ASPEED
determined that the reference pinmux configuration tables were in error
and the SCU documentation contained the correct configuration. Update
the driver to reflect the state described in the SCU documentation.

The AST2600 pinmux is fairly similar to the previous generations of
ASPEED BMC SoCs in terms of architecture, though differ in some of the
design details. The complexity of the pin expressions is largely reduced
(e.g. there are no-longer signals with multiple expressions muxing them
to the associated pin), and there are now signals and buses with
multiple pin groups.
The driver implements pinmux support for all 244 GPIO-capable pins plus
a further four pins that are not GPIO capable but which expose multiple
signals. pinconf will be implemented in a follow-up patch.
The implementation has been smoke-tested under qemu, and run on hardware
by ASPEED.
