From 5ff776889212c080e3d1a33634ac904405ed6845 Mon Sep 17 00:00:00 2001 From: Christoph Muellner Date: Wed, 2 Jan 2019 15:09:18 +0100 Subject: dm: pinctrl: Add pinctrl_decode_pin_config_dm(). pinctrl_decode_pin_config_dm() is basically a feature-equivalent implementation of pinctrl_decode_pin_config(), which operates on struct udevice devices and uses the dev_read_*() API.
