From: Maxime Ripard Date: Wed, 16 Dec 2015 16:39:42 +0000 (+0800) Subject: pinctrl: sunxi: Add A80 special pin controller X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0eccc9cb4c1443c2665466e35f6e138381b8afd9;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git pinctrl: sunxi: Add A80 special pin controller Like the previous designs, the A80 has a special pin controller for the critical pins, like the PMIC bus. Add a driver for this controller.
