Subject: [PATCH v4 00/15] pinctrl: add BCM63XX pincontrol support

First of all, I've based this on the patches sent by Jonas Gorski back in
2016:
https://www.spinics.net/lists/linux-gpio/msg15983.html
http://patchwork.ozlabs.org/project/linux-gpio/patch/1471604025-21575-2-git-send-email-jonas.gorski@gmail.com/

I've tried to address all coments from Linus Walleij, but I know that
this may still need some other modifications

This patchset adds appropriate binding documentation and drivers for
pin controller cores found in the BCM63XX MIPS SoCs currently supported.

While the GPIO part is always the same, the pinmux part varies quite a
lot between different SoCs. Sometimes they have defined groups which
can be muxed into different functions, sometimes each function has a
different group. Sometimes you can mux individual pins. Often it is a
combination of single pins and groups.

Some core versions require the GPIO direction to be set according to the
function, most do not. Sometimes the mux register(s) contain bits for
unrelated other functions.

v4: fix gpiochip_irqchip_add_domain(), remove IRQ Kconfig selections and add
 missing of_node_put().
v3: introduce new files for shared code and add more changes suggested by
 Linus Walleij. Also add a new patch needed for properly parsing gpio-ranges.
v2: introduce changes suggested by Linus Walleij and remove interrupts
 - In order to use GPIO_REGMAP, the need to get gpio_chip from gpio_regmap
 and use it for pinctrl_add_gpio_range() and gpio_chip.direction_input()
 and gpio_chip.direction_output().
