gpio: gpio-mm: Implement and utilize register structures

2022-07-20T15:44:47+00:00

Reduce magic numbers and improve code readability by implementing and
utilizing named register data structures. The GPIO-MM device features an
Intel 8255 compatible GPIO interface, so the i8255 GPIO module is
selected and utilized as well.

gpio: i8255: Introduce the Intel 8255 interface library module

2022-07-20T15:44:36+00:00

Exposes consumer library functions providing support for interfaces
compatible with the venerable Intel 8255 Programmable Peripheral
Interface (PPI).

The Intel 8255 PPI first appeared in the early 1970s, initially for the
Intel 8080 and later appearing in the original IBM-PC. The popularity of
the original Intel 8255 chip led to many subsequent variants and clones
of the interface in various chips and integrated circuits. Although
still popular, interfaces compatible with the Intel 8255 PPI are
nowdays typically found embedded in larger VLSI processing chips and
FPGA components rather than as discrete ICs.

A CONFIG_GPIO_I8255 Kconfig option is introduced by this patch. Modules
wanting access to these i8255 library functions should select this
Kconfig option, and import the I8255 symbol namespace.

gpio: remove VR41XX related gpio driver

2022-07-19T09:27:06+00:00

Commit d3164e2f3b0a ("MIPS: Remove VR41xx support") removed support
for MIPS VR41xx platform, so remove exclusive drivers for this
platform, too.

gpio: GPIO_SAMA5D2_PIOBU should depend on ARCH_AT91

2022-07-19T07:57:41+00:00

The SAMA5D2 PIOBU is only present on some AT91/Microchip SoCs.  Hence
add a dependency on ARCH_AT91, to prevent asking the user about this
driver when configuring a kernel without AT91/Microchip SoC support.

irq/gpio: ixp4xx: Drop boardfile probe path

2022-04-25T18:53:18+00:00

The boardfiles for IXP4xx have been deleted. Delete all the
quirks and code dealing with that boot path and rely solely on
device tree boot.

Fix some missing static keywords that the kernel test robot
was complaining about while we're at it.

There are some special clock amendments for two machines
formerly detected by their machine_is() boardfile macro.

They are now migrated to device tree so use
of_machine_is_compatible() instead.
