16ccaf5bb5 pinctrl: sh-pfc: Accept standard function, pins and groups properties
The "function", "pins" and "groups" pinmux and pinctrl properties have
been standardized. Support them in addition to the custom "renesas,*"
properties. New-style and old-style properties can't be mixed in DT.

43c4436e2f pinctrl: sh-pfc: add R8A7794 PFC support
Add PFC support for  the  R8A7794 SoC  including pin groups for some
on-chip devices such as ETH, I2C, INTC, MSIOF, QSPI, [H]SCIF...

Sergei: squashed together several patches, fixed the MLB_CLK typo,
added IRQ4.. IRQ9 pin groups, fixed IRQn comments, added ETH B pin
group names, removed stray new line and fixed typos in the  comments
in the pinmux_config_regs[] initializer, removed the platform device
ID, took into account limited number of signals in the GPIO1/5/6
controllers, added reasonable and removed unreasonable
copyrights, modified the bindings document, renamed, added changelog.

Changes in version 5:
- resolved rejects, refreshed the patch;
- added Laurent Pinchart's ACK.

Changes in version 4:
- reused the PORT_GP_26() macro to #define PORT_GP_28().

Changes in version 3:
- removed the platform device ID;
- added PORT_GP_26() and PORT_GP_28() macros, used them for GPIO1/5/6 in the
  CPU_ALL_PORT() macro.

Changes in version 2:
- rebased the patch.

4281a16de2 sh-pfc: Add renesas,pfc-r8a7791 to binding documentation
The driver already supports the r8a7791 SoC, and "renesas,pfc-r8a7791"
is already in use.

70c8f01a35 sh-pfc: Support GPIO to IRQ mapping specified IRQ resources
On non-DT platforms IRQ controllers associated with the GPIOs have a
fixed IRQ base value known at compile time. The sh-pfc driver translates
GPIO number to IRQ numbers using a hardcoded table. This mechanism
breaks on DT platforms, as the IRQ base values are dynamic in that case.

Fix this by specifying IRQs associated with GPIOs in IRQ resources,
populated automatically from the device tree. When IRQ resources are
specified the driver requires one IRQ resource per GPIO able to generate
an interrupt, and uses the translation table to compute the IRQ resource
offset instead of the IRQ number.

fe1c9a822c sh-pfc: Add DT support
Support device instantiation through the device tree. The compatible
property is used to select the SoC pinmux information.

Set the gpio_chip device field to the PFC device to enable automatic
GPIO OF support.
