pinctrl: rockchip: add support for multiple bank types
From: Heiko Stuebner <heiko@...> Date: Sat, 5 Oct 2013 11:41:29 +0200
Commit-Message
There are Rockchip SoCs, namely the rk3188, that combine a set of regular banks with banks that need special handling for some settings. Therefore add the possibility for the driver to handle more than one bank type. Signed-off-by: Heiko Stuebner <heiko@...>
