Subject: [PATCH AUTOSEL 4.19 094/219] pinctrl: sh-pfc: r8a77990: Fix MOD_SEL0 SEL_I2C1 field width
Date: Fri, 22 Nov 2019 00:47:06 -0500	[thread overview]
Message-ID: <20191122054911.1750-87-sashal@kernel.org> (raw)
In-Reply-To: <20191122054911.1750-1-sashal@kernel.org>

From: Geert Uytterhoeven <geert+renesas@glider.be>

[ Upstream commit 755a5b805fa7ff22e2934d67501efd92109f41ea ]

The SEL_I2C1 (MOD_SEL0[21:20]) field in Module Select Register 0 has a
width of 2 bits, i.e. it allows programming one out of 4 different
configurations.
However, the MOD_SEL0_21_20 macro contains 8 values instead of 4,
overflowing into the subsequent fields in the register, and thus breaking
the configuration of the latter.

Fix this by dropping the bogus last 4 values, including the non-existent
SEL_I2C1_4 configuration.

Fixes: 6d4036a1e3b3ac0f ("pinctrl: sh-pfc: Initial R8A77990 PFC support")
