From f868ef995b32f0f08d7b6ce700bbe25de3ad65ac Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Tue, 8 Jan 2013 22:43:12 +0100 Subject: [PATCH] pinctrl: pinconf-generic: add drive strength parameter Some pin configurations IP allows to set the current output to the pin. This patch adds such a parameter to the pinconf-generic mechanism. This parameter takes as argument the drive strength in mA.
