Subject: [cip-dev] [PATCH 20/36] pinctrl: sh-pfc: r8a7795: Add I2C{0,3,5} pins, groups and functions
Date: Fri, 21 Aug 2020 10:42:56 +0100 [thread overview]

From: Takeshi Kihara <takeshi.kihara.df@renesas.com>
commit 100431b61dc5a591913b16971af644d8bf622599 upstream.
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.
