From d3e5116119bd02ea7716bbe04b39c21bba4bcf42 Mon Sep 17 00:00:00 2001 From: Heiko Stübner Date: Mon, 10 Jun 2013 22:16:22 +0200 Subject: 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.
