035f90076f pinctrl: add a Cirrus ep93xx SoC pin controller
Add a pin control (only multiplexing) driver for ep93xx SoC so
we can fully convert ep93xx to device tree.

This driver is capable of muxing ep9301/ep9302/ep9307/ep9312/ep9315
variants, this is chosen based on "compatible" in device tree.

a3116c8881 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.

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

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

576623d706 pinctrl: Add driver for Awinic AW9523/B I2C GPIO Expander
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.

37c646dc51 pinctrl: Add support for the Lantic PEF2256 pinmux
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.

40ed50cc3d pinctrl: mlxbf3: remove broken Kconfig 'select'
The new pinctrl driver selects GPIO_MLXBF3, but that can not be enabled yet because
the MELLANOX_PLATFORM symbol does not exist in the tree:

WARNING: unmet direct dependencies detected for GPIO_MLXBF3
  Depends on [n]: GPIOLIB [=y] && PCI [=n] && (MELLANOX_PLATFORM [=n] && ARM64 [=y] || COMPILE_TEST [=y])
  Selected by [y]:
  - PINCTRL_MLXBF3 [=y] && PINCTRL [=y] && (MELLANOX_PLATFORM [=n] && ARM64 [=y] || COMPILE_TEST [=y])

As it turns out, the pinctlr driver still builds fine without this, so just
remove the select statement.

41ef3c1a6b pinctrl: Don't allow PINCTRL_AMD to be a module
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.

ec648f6b76 pinctrl: starfive: Add pinctrl driver for StarFive SoCs
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.

Datasheet: https://github.com/starfive-tech/JH7100_Docs/blob/main/JH7100%20Data%20Sheet%20V01.01.04-EN%20(4-21-2021).pdf

user about this driver when configuring a kernel without Rockchip
platform support.

Note that before, the PINCTRL_ROCKCHIP symbol was not visible, and
automatically selected when needed.  By making it tristate and
user-selectable, it became visible for everyone.

8b83369ddc RISC-V Patches for the 5.12 Merge Window
I have a handful of new RISC-V related patches for this merge window:
 
 * A check to ensure drivers are properly using uaccess.  This isn't
   manifesting with any of the drivers I'm currently using, but may catch
   errors in new drivers.
 * Some preliminary support for the FU740, along with the HiFive
   Unleashed it will appear on.
 * NUMA support for RISC-V, which involves making the arm64 code generic.
 * Support for kasan on the vmalloc region.
 * A handful of new drivers for the Kendryte K210, along with the DT
   plumbing required to boot on a handful of K210-based boards.
 * Support for allocating ASIDs.
 * Preliminary support for kernels larger than 128MiB.
 * Various other improvements to our KASAN support, including the
   utilization of huge pages when allocating the KASAN regions.
 
 We may have already found a bug with the KASAN_VMALLOC code, but it's
 passing my tests.  There's a fix in the works, but that will probably
 miss the merge window.
