9836b1ac2d dt: bindings: add binding for Allwinner A64 R_PIO pinctrl
Allwinner A64 SoC has also a dedicated pin controller for Port L GPIOs,
which is called "Port Controller (CPUs-PORT)" in SoC User Manual.

Add a binding for this pin controller, like the ones in A23/33 and H3.

caf9db13a7 dt-bindings: fix for Allwinner H5 pinctrl's compatible
The compatible for Allwinner H5 pin controller is wrong written as
allwinner,sun50i-h5-r-pinctrl, however, it's really a generic pinctrl
rather than a "r" one.

Fix this compatible string.

4091fb95b5 scripts/spelling.txt: add "followings" pattern and fix typo instances
Fix typos and add the following to the scripts/spelling.txt:

  followings||following

While we are here, add a missing colon in the boilerplate in DT binding
documents.  The "you SoC" in allwinner,sunxi-pinctrl.txt was fixed as
well.

I reworded "as the followings:" to "as follows:" for
drivers/usb/gadget/udc/renesas_usb3.c.

838adb576d drivers: pinctrl: add driver for Allwinner H5 SoC
Based on the Allwinner H5 datasheet and the pinctrl driver of the
backward-compatible H3 this introduces the pin multiplex assignments for
the H5 SoC.

H5 introduced some more pin functions (e.g. three more groups of TS
pins, and one more groups of SIM pins) than H3.

7c926492d3 pinctrl: sunxi: Add support for interrupt debouncing
The pin controller found in the Allwinner SoCs has support for interrupts
debouncing.

However, this is not done per-pin, preventing us from using the generic
pinconf binding for that, but per irq bank, which, depending on the SoC,
ranges from one to five.

Introduce a device-wide property to deal with this using a microsecond
resolution. We can re-use the per-pin input-debounce property for that, so
let's do it!

96851d391d drivers: pinctrl: add driver for Allwinner A64 SoC
Based on the Allwinner A64 user manual and on the previous sunxi
pinctrl drivers this introduces the pin multiplex assignments for
the ARMv8 Allwinner A64 SoC.
Port A is apparently used for the fixed function DRAM controller, so
the ports start at B here (the manual mentions "n from 1 to 7", so
not starting at 0).

d8323c6b03 pinctrl: sunxi: Add custom irq_domain_ops
The current interrupt parsing code was working by accident, because the
default was actually parsing the first node of interrupts.

While that was mostly working (and the flags were actually ignored), this
binding has never been documented, and doesn't work with SoCs that have
multiple interrupt banks anyway.

Add a proper interrupt xlate function, that uses the same description than
the GPIOs (<bank> <pin> <flags>), that will make things less confusing.

The EINT number will still be used as the hwirq number, but won't be
exposed through the DT.

47cf4b326c pinctrl: sun6i: Add A31s pinctrl support
The A31s is a stripped down version of the A31, as such it is missing some
pins and some functions on some pins.

The new pinctrl-sun6i-a31s.c this commit adds is a copy of pinctrl-sun6i-a31s.c
with the missing pins and functions removed.

Note there is no a31s specific version of pinctrl-sun6i-a31-r.c, as the
prcm pins are identical between the A31 and the A31s.

0e37f88d9a ARM: sunxi: Add pinctrl driver for Allwinner SoCs
The Allwinner SoCs have an IP module that handle both the muxing and the
GPIOs.

This IP has 8 banks of 32 bits, with a number of pins actually useful
for each of these banks varying from one to another, and depending on
the SoC used on the board.

This driver only implements the pinctrl part, the gpio part will come
eventually.
