69c308e2bc pinctrl: pinconf-generic: add "input-schmitt" DT property
PIN_CONFIG_INPUT_SCHMITT is defined in enum_pin_config_param,
but the corresponding DT property is missing.

3c4b23dd71 pinctrl: pinconf-generic: sort pin configuration params alphabetically
Currently, the dt_params array in drivers/pinctrl/pinconf-generic.c
is not sorted in the same order as the enum pin_config_param in
include/linux/pinctrl/pinconf-generic.h.

Sort enum pin_config_param, conf_items, dt_params, alphabetically
for consistency.

2b67bccb47 pinctrl: sh-pfc: modify PINMUX_IPSR_MSEL() macro order
The difference between PINMUX_IPSR_MSEL() and PINMUX_IPSR_MODSEL_DATA()
are FN_xxx order, and PINMUX_IPSR_MSEL() is used only from r8a7778.
Now it r8a7778 works correctly with PINMUX_IPSR_MODSEL_DATA() order.
This means we can merge PINMUX_IPSR_MSEL() and PINMUX_IPSR_MODSEL_DATA().

Current PFC driver is very difficult to read, because macro names are

4adeabd042 pinctrl: sh-pfc: Remove hardcoded IRQ numbers
Now that all ARM-based Renesas SoCs use multiplatform kernels only the
hardcoded IRQ numbers can be dropped as they're dynamically allocated.

90d066130f pinctrl: sh-pfc: Get rid of CONFIG_ARCH_SHMOBILE_LEGACY
Shmobile is all multiplatform these days, so get rid of the reference to
CONFIG_ARCH_SHMOBILE_LEGACY.

Move the legacy code to do the non-DT mapping between GPIOs and pins
inside the existing #ifdef CONFIG_SUPERH section.

9e21461453 pinctrl: sh-pfc: r8a7791/r8a7793: Correct SCIFB1_B SCK MOD_SEL value
When using serial port SCIFB1_B, transmit works, but nothing is
received.

Receive fails because the SCIFB1_SCK_B settings configure the wrong
value for the sel_scifb1 field in the Module Select Register (MOD_SEL),
due to an ambiguity in the R-Car M2-W and M2-N datasheets.

Tested on r8a7791/koelsch using pins 53 (TXD) and 72 (RXD) on EXIO
Connector A.

18fab3995e pinctrl: sh-pfc: Stop calling gpiochip_add_pin_range() on DT platforms
On platforms where the PFC/GPIO controller is instantiated from DT, the
mapping between GPIOs and pins is set up using the "gpio-ranges"
property in DT.

Hence stop setting up the mapping from C code on DT platforms.
This code is still used for SH or ARM-legacy platforms.
