Subject: [PATCH] pinctrl: renesas: r8a779a0: Add I2C pins, groups and functions
Date: Tue,  1 Dec 2020 12:06:41 +0100	[thread overview]
Message-ID: <20201201110641.28986-1-uli+renesas@fpond.eu> (raw)

This patch adds I2C0-6 pins, groups and functions to the R8A779A0 (V3U)
SoC.

Signed-off-by: Ulrich Hecht <uli+renesas@fpond.eu>

Hi!

This patch was missing from the "pinctrl: renesas: basic R8A779A0 (V3U)
support" series. I have thus posted it on its own for review now and will
include it in v2 of the series later.

CU
Uli
