From 100431b61dc5a591913b16971af644d8bf622599 Mon Sep 17 00:00:00 2001 From: Takeshi Kihara Date: Fri, 16 Nov 2018 15:20:49 +0800 Subject: [PATCH] pinctrl: sh-pfc: r8a7795: Add I2C{0,3,5} pins, groups and functions This patch adds I2C{0,3,5} pins, groups and functions to the R8A7795 SoC. These pins are physically muxed with other pins. Therefore, setup of MOD_SEL is needed for exclusive control with other pins.
