From 9c6a3c6772c4aa53bed0b233621637af2e3eb83e Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 27 Aug 2015 12:44:30 +0900 Subject: pinctrl: sandbox: add sandbox pinctrl driver This driver actually does nothing but test pinctrl uclass, and demonstrate how things work. To try this driver, uncomment /* #define DEBUG */ in the drivers/pinctrl/pinctrl-sandbox.c, and debug messages will be displayed.
