When set, this GPIO controller has pins associated with the
keyboard controller. In this case the reg_gpcr property is
overloaded and used to write the keyboard GCTRL register

FU540 SoC has 16 GPIOs, this way, the GPIO API can perform correct
asserts when a pin is provided. Note that default is 32, correct for eg
FE310.

Define the edge-trigger register base address based on whether
the PLIC node in the devicetree has an additional compatible
that supports edge-triggered interrupt.
Limited the implementation to Andes NCEPLIC100 only, updated
the devicetree binding of `andes_v5_ae350` accordingly.

Microchip's PolarFire SoC has a total of 9 contexts associated with the
Platform Interrupt controller (PLIC). the E51 core has a single context
(M Mode), and the application processor U54 cores have two each (M mode
and S mode, respectively)
While we are at it, there are a total of 186 interrupts, not 187.

Microchip's PolarFire SoC (device family name: MPFS) is not specific to
the Icicle Kit. Rename the devicetree sources to be more generic and to
align with Linux and allow for other development boards to adopt.

Add a property for I2C channel switch selection. This property will
write to the SMBxxCHS register according to the I2C node you selected,
which can make channel swapping.

Refactor the pinctrl nodes slightly so that the port devices are not
child of the main pinctrl node. This is because the pinctrl node is
being used as parent for pinctrl setting nodes itself, and having the
port nodes as child end up creating a circular depdency with the edt
child enumeration patch.

Update the descriptions for the various CAN devicetree timing properties
specified in Time Quanta (TQ) to make it clear that these, if present, are
only used for the initial timing parameters.
Deprecate the (Re-)Synchronization Jump Width (SJW) devicetree properties
for both arbitration and data phase timing as these are now only used in
combination with the other TQ-based CAN timing properties, which are all
deprecated.

This commit adds/modifies `riscv,isa` strings using the following rules:
* the ISA string is lowercase
* multi-letter extensions are preceded with the underscore mark
* if an extension is implied by another one, it is not specified - e.g. the
D extension implies the F extension, so writing `rv32ifd` is redundant

Sometimes, channel C may write wrong register to the target device.
This issue occurs when FIFO2 is enabled on channel C. The problem
arises because FIFO2 is shared between channel B and channel C.
FIFO2 will be disabled when data access is completed, at which point
FIFO2 is set to the default configuration for channel B.
The byte counter of FIFO2 may be affected by channel B. There is a
chance that channel C may encounter wrong register being written due
to the FIFO2 byte counter wrong write after channel B's write operation.
The current workaround is that channel C cannot use FIFO mode.
