RISC-V SoC Kconfig Updates for v6.10

A few different bits of SoC-related Kconfig work. The first part of
this is shared with the DT updates - the modification of all SOC_CANAAN
users to SOC_CANAAN_K210 to split the existing m-mode nommu k210 away
from the k230 that is able to be used in a "common" kernel.

The other thing here is the removal of most of the SOC_VENDOR options,
with their ARCH_VENDOR equivalents that've been waiting in the wings for
1 year+ now made visible. Due a lapse on my part when originally adding
the ARCH_VENDOR stuff, the Microchip transition isn't complete - the
_POLARFIRE was a mistake to keep as there's gonna be non-PolarFire
RISC-V stuff from Microchip soonTM.

pinctrl: Implementation of the generic scmi-pinctrl driver

2024-04-19T14:17:37+00:00

scmi-pinctrl driver implements pinctrl driver interface and using
SCMI protocol to redirect messages from pinctrl subsystem SDK to
SCMI platform firmware, which does the changes in HW.

pinctrl: k210: Deprecate SOC_CANAAN and use SOC_CANAAN_K210

2024-04-05T15:42:50+00:00

Since SOC_FOO should be deprecated from patch [1], and cleanup for other
SoCs is already in the mailing list [2,3,4], we remove the use of
SOC_CANAAN and introduced SOC_CANAAN_K210 for K210-specific drivers,

Thus, we replace its drivers depends on SOC_CANAAN_K210 and default select
when it has the symbol SOC_CANAAN_K210.

pinctrl: aw9523: Make the driver tristate

2024-03-07T22:09:01+00:00

The AW9523 driver fails to build in some allmod configs since the
I2C core can be a module, but AW9523 can not. Fix it up by allowing
AW9523 to be a module (tristate).

pinctrl: Add driver for Awinic AW9523/B I2C GPIO Expander

2024-03-05T22:26:31+00:00

The Awinic AW9523(B) is a multi-function I2C gpio expander in a
TQFN-24L package, featuring PWM (max 37mA per pin, or total max
power 3.2Watts) for LED driving capability.

It has two ports with 8 pins per port (for a total of 16 pins),
configurable as either PWM with 1/256 stepping or GPIO input/output,
1.8V logic input; each GPIO can be configured as input or output
independently from each other.

This IC also has an internal interrupt controller, which is capable
of generating an interrupt for each GPIO, depending on the
configuration, and will raise an interrupt on the INTN pin to
advertise this to an external interrupt controller.

Merge tag 'pef2256-framer' into devel

Immutable tag for the PEF2256 framer

pinctrl: Add support for the Lantic PEF2256 pinmux

2023-12-12T22:05:24+00:00

The Lantiq PEF2256 is a framer and line interface component designed to
fulfill all required interfacing between an analog E1/T1/J1 line and the
digital PCM system highway/H.100 bus.

This kind of component can be found in old telecommunication system.
It was used to digital transmission of many simultaneous telephone calls
by time-division multiplexing. Also using HDLC protocol, WAN networks
can be reached through the framer.

This pinmux support handles the pin muxing part (pins RP(A..D) and pins
XP(A..D)) of the PEF2256.
