pinctrl: sh-pfc: r8a77965: Add DU RGB output pins, groups and functions
Browse files Browse the repository at this point in the history 
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 Söderlund
<niklas.soderlund+renesas@ragnatech.se>.
