Merge tag 'renesas-pinctrl-for-v5.11-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers into devel

pinctrl: renesas: Updates for v5.11

  - Add remaining video-in (VIN) pin groups on R-Car H2 and RZ/G1H,
  - Image size optimizations and code consolidations,
  - Minor fixes and improvements.

The only usage of sh73a0_vccq_mc0_ops is to assign its address to the
ops field in the regulator_desc struct, which is a const pointer. Make
it const to allow the compiler to put it in read-only memory.

On SuperH and ARM SH/R-Mobile SoCs, the pin control driver handles
GPIOs, too.  To reduce code size when compiling a kernel supporting only
modern SoCs, most, but not all, of the GPIO functionality is protected
by checks for CONFIG_PINCTRL_SH_FUNC_GPIO.

Factor out the remaining parts when not needed:
  1. sh_pfc_soc_info.{in,out}put describe GPIO pins that have input
     resp. output capabilities (SuperH and SH/R-Mobile).
  2. sh_pfc_soc_info.gpio_irq{,_size} describe the mapping from GPIO
     pins to interrupt numbers (SH/R-Mobile).
  3. sh_pfc_gpio_set_direction() configures GPIO direction, called from
     the GPIO driver through pinctrl_gpio_direction_{in,out}put()
     (SH/R-Mobile).  Unfortunately this function cannot just be moved to
     drivers/pinctrl/renesas/gpio.c, as it relies on knowledge of
     sh_pfc_pinctrl, which is internal to
     drivers/pinctrl/renesas/pinctrl.c.

While code size reduction is minimal, this does help in documenting
depencies.

Currently, the rcar_pinmux_[gs]et_bias() helpers handle only SoCs that
have separate LSI Pin Pull-Enable (PUEN) and Pull-Up/Down Control (PUD)
registers, like R-Car Gen3 and RZ/G2.  Update the function to handle
SoCs that have only LSI Pin Pull-Up Control Register (PUPR), like R-Car
Gen1/Gen2 and RZ/G1.

Reduce code duplication by converting the R-Car M1A pin control driver
to use the common handler.

Note that this changes behavior in case the (invalid!) option
"bias-pull-down" is used in an R-Car M1A DTS: before, it was ignored
silently; after this change, it is considered the same as
"bias-pull-up".

The handling of the LSI Pin Pull-Up Control Registers (PUPR) on R-Car
M1A uses register offsets instead of register physical addresses.
This is different from the handling on other R-Car parts.

Convert the bias handling from register offsets to physical addresses.
This increases uniformity, and prepares for consolidation of the bias
handling.

Shrink sh_pfc_pin_config from 8 to 2 bytes:
  - The mux_set flag can be removed, as a non-zero mark value means the
    same (zero = PINMUX_RESERVED is an invalid mark value),
  - The gpio_enabled flag needs only a single bit,
  - Mark values are small integers, and can easily fit in a 15-bit
    bitfield.

This saves 6 bytes per pin when allocating the sh_pfc_pinctrl.configs
array, i.e. it reduces run-time memory consumption by ca. 1.5 KiB.

On arm64, pointer size and alignment is 64-bit, hence a 4-byte hole is
present in between the enum_id and name members of the sh_pfc_pin
structure.  Get rid of this hole by sorting the structure's members by
decreasing size.

This saves up to 1.5 KiB per enabled SoC, and reduces the size of a
kernel including support for all R-Car Gen3 SoCs by more than 10 KiB.

This has no size impact on SH and arm32.

Allow the qcom_scm driver to be loadable as a permenent module.

This still uses the "depends on QCOM_SCM || !QCOM_SCM" bit to
ensure that drivers that call into the qcom_scm driver are
also built as modules. While not ideal in some cases its the
only safe way I can find to avoid build errors without having
those drivers select QCOM_SCM and have to force it on (as
QCOM_SCM=n can be valid for those drivers).

This patch reworks PINCTRL_MSM to be a visible option, and
instead of having the various SoC specific drivers select
PINCTRL_MSM, this switches those configs to depend on
PINCTRL_MSM.

This is useful, as it will be needed in order to cleanly support
having the qcom-scm driver, which pinctrl-msm calls into,
configured as a module. Without this change, we would eventually
have to add dependency lines to every config that selects
PINCTRL_MSM, and that would becomes a maintenance headache.

We also add PINCTRL_MSM to the arm64 defconfig to avoid
surprises as otherwise PINCTRL_MSM/IPQ* options previously
enabled, will be off.

Add the "lcd-8bit" group to the "lcd" function.

As "lcd-24bit" is a superset of "lcd-8bit", in theory the former could
be modified to only contain the pins not already included in "lcd-8bit",
just like how it's done for the JZ4740 and JZ4725B platforms. However,
we can't do that without breaking Device Tree ABI, so in that case we
have no choice but to have two groups containing the same pins.

Abuse the pin function pointer to store the pin function value directly,
when all the pins of a group have the same function value. Now when the
pointer value is <= 3 (unsigned), the pointer value is used as the pin
function; otherwise it is used as a regular pointer.

This drastically reduces the number of pin function tables needed, and
drops .data usage by about 2 KiB. Additionally, the few pin function
tables that are still around now contain u8 instead of int, since the
largest number that will be stored is 3.
