Heiko Stübner 44b6d93043 pinctrl: rockchip: correctly handle arguments of pinconf options
Change the rockchip pinctrl driver to handle the arguments to the pull
pinconfig options correctly. So only accept non-0 values for the
pull options as the rockchip pin-controller can only turn pulls on and
off (this via BIAS_DISABLE).

Heiko Stübner d3e5116119 pinctrl: add pinctrl driver for Rockchip SoCs
This driver adds support the Cortex-A9 based SoCs from Rockchip,
so at least the RK2928, RK3066 (a and b) and RK3188.
Earlier Rockchip SoCs seem to use similar mechanics for gpio
handling so should be supportable with relative small changes.
Pull handling on the rk3188 is currently a stub, due to it being
a bit different to the earlier SoCs.

Pinmuxing as well as gpio (and interrupt-) handling tested on
a rk3066a based machine.
