[PATCH v2 02/11] pinctrl: sh-pfc: r8a77965: Add DU RGB output pins, groups and functions

From: Kieran Bingham
Date: Fri Apr 27 2018 - 13:03:20 EST


This patch adds pins, groups and functions for parallel RGB output
signals from DU. The HDMI and TCON pins are added to separate groups.

Based on a similar patch of the R8A7796 PFC driver by Niklas SÃderlund
<niklas.soderlund+renesas@xxxxxxxxxxxx>.
