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.
Thanks,
Thomas.
