"Outside the pinctrl driver and DT bindings we hit some Arm DT files,
patched by the maintainers.

Other than that it is business as usual.

Core changes:

- Add PINCTRL_PINGROUP() helper macro (and use it in the AMD driver).

New drivers:

- Intel Meteor Lake support.

- Reneasas RZ/V2M and r8a779g0 (R-Car V4H).

- AXP209 variants AXP221, AXP223 and AXP809.

- Allwinner D1.

Improvements:

- Proper pin multiplexing in the AMD driver.

- Mediatek MT8192 can use generic drive strength and pin bias, then
fixes on top plus some I2C pin group fixes.

- Have the Allwinner Sunplus SP7021 use the generic DT schema and
make interrupts optional.

- Handle Qualcomm SC7280 ADSP.

- Handle Qualcomm MSM8916 CAMSS GP clock muxing.

- High impedance bias on ZynqMP.

- Serialize StarFive access to MMIO.

- Immutable gpiochip for BCM2835, Ingenic, Qualcomm SPMI GPIO"

pinctrl: Don't allow PINCTRL_AMD to be a module

2022-07-18T10:47:28+00:00

It was observed that by allowing pinctrl_amd to be loaded
later in the boot process that interrupts sent to the GPIO
controller early in the boot are not serviced.  The kernel treats
these as a spurious IRQ and disables the IRQ.

This problem was exacerbated because it happened on a system with
an encrypted partition so the kernel object was not accesssible for
an extended period of time while waiting for a passphrase.

To avoid this situation from occurring, stop allowing pinctrl-amd
from being built as a module and instead require it to be built-in
or disabled.

2022-01-12T18:56:08+00:00

Pull pin control bulk updates from Linus Walleij:
"Core changes:

- New standard enumerator and corresponding device tree bindings for
output impedance pin configuration. (Implemented and used in the
Renesas rzg2l driver.)

- Cleanup of Kconfig and Makefile to be somewhat orderly and
alphabetic.

New drivers:

- Samsung Exynos 7885 pin controller.

- Ocelot LAN966x pin controller.

- Qualcomm SDX65 pin controller.

- Qualcomm SM8450 pin controller.

- Qualcomm PM8019, PM8226 and PM2250 pin controllers.

- NXP/Freescale i.MXRT1050 pin controller.

- Intel Thunder Bay pin controller.

Enhancements:

- Introduction of the string library helper function
"kasprintf_strarray()" and subsequent use in Rockchip, ST and
Armada pin control drivers, as well as the GPIO mockup driver.

- The Ocelot pin controller has been extensively rewritten to use
regmap and other modern kernel infrastructure.

- The Microchip SGPIO driver has been converted to use regmap.

- The SPEAr driver had been converted to use regmap.

- Substantial cleanups and janitorial on the Apple pin control driver
that was merged for v5.16.

- Janitorial to remove of_node assignments in the GPIO portions that
anyway get this handled in the GPIO core.

- Minor cleanups and improvements in several pin controllers"

pinctrl: starfive: Add pinctrl driver for StarFive SoCs

2021-12-16T16:24:23+00:00

Add a combined pinctrl and GPIO driver for the JH7100 RISC-V SoC by
StarFive Ltd. This is a test chip for their upcoming JH7110 SoC, which
is said to feature only minor changes to these pinctrl/GPIO parts.

For each "GPIO" there are two registers for configuring the output and
output enable signals which may come from other peripherals. Among these
are two special signals that are constant 0 and constant 1 respectively.
Controlling the GPIOs from software is done by choosing one of these
signals. In other words the same registers are used for both pin muxing
and controlling the GPIOs, which makes it easier to combine the pinctrl
and GPIO driver in one.

I wrote the pinconf and pinmux parts, but the GPIO part of the code is
based on the GPIO driver in the vendor tree written by Huan Feng with
cleanups and fixes by Drew and me.

While at it fix some style issues, such as:
  - "Say Y"/"Say yes"/"Say Yes" --> "Say Y"
  - "pullup/pulldown" --> "pull-up and pull-down"
  - wrong indentation

About Intel Thunder Bay:
-----------------------
Intel Thunder Bay is a computer vision AI accelerator SoC based on ARM CPU.

Pinctrl IP:
----------
The SoC has a customised pinmux controller IP which controls pin
multiplexing and configuration.

Thunder Bay pinctrl IP is not based on and have nothing in common with the
existing pinctrl drivers. The registers used are incompatible with the
existing drivers, so it requires a new driver.

Add pinctrl driver to enable pin control support in the Intel Thunder Bay
SoC.
