From 636f8ba67fb606a4a0ab4deedb39c71d1ea5dc8a Mon Sep 17 00:00:00 2001 From: Paul Cercueil Date: Fri, 12 May 2017 18:53:01 +0200 Subject: MIPS: JZ4740: Qi LB60: Add pinctrl configuration for several drivers We set the pin configuration for the jz4740-nand, jz4740-mmc, jz4740-fb, jz4740-pwm and jz4740-uart drivers. This will permit those drivers to be cleaned out of the custom GPIO code that they currently use.
