* pinctrl: Add mux options 3 and 4 for rockchip pinctrlDoug Anderson2014-08-281-0/+2
| | | | | | | | | Newer Rockchip SoCs have more muxing slots. Add slots 3 and 4 since the rk3288 table goes all the way up to 4. Signed-off-by: Doug Anderson <dianders@chromium.org> Reviewed-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* pinctrl: add pinctrl driver for Rockchip SoCsHeiko Stübner2013-06-161-0/+32
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.
