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. I intentionally left out any MIPS patches so keep the patchset smaller and to make it clearer to which tree this belongs. Some implementation notes: BCM6348 has one mux function that enables two unrelated functions at the same time; additional SPI CS signals as well as extra UART pins. This means that in case both the uart as well as the spi driver needs it, it would need to be requested globally, as the same mux can't be requested by two different devices. Since this is a linux internal detail, I chose to not try to split this function and try to work around it in the driver (by refcounting etc). BCM6358 has two "invert-mii-clock" bits in its GPIO Mode register for the ethernet cores. This didn't seem to fit well into pinmux/conf; at best as two pins which you could apply exactly one property, "brcm,invert-clock". So I chose syscon so the ethernet driver can poke at the bits itself. BCM6368 has several additional bits in its GPIO BaseMode register for enabling RGMII pins, UTOPIA, or changing the PCI clock to 66 MHz. These seemed to fit even less. Based on the current HEAD of linux-pinctrl/for-next.
