Samsung pinctrl driver was written to be usable on all of the Samsung application processors starting from 24xx series to the latest Exynos5. The gpio/pinmux/pinconfig controllers on these SoC have varying capabilities. Some of the banks in s3c24xx series support mux function but do not support pull up/down (pud) or driver strength (drv). s3c64xx soc's have banks that support pin mux and 'pud' but do not support 'drv'. And there are banks that do not support mux function but support 'pud' and 'drv'. Further, a given SoC can have multiple combinations of different bank types. In addition to this, there are two more properties for mux and pud values in power down mode in some of the samsung SoC's. To keep the bindings common across all the possible Samsung SoC's, the mux, pud and drv properties were split so that the parsing code in the Samsung pinctrl driver remains generic for all the possible combinations of pin banks and SoC's.
