Subject: [PATCH AUTOSEL 4.9 01/35] pinctrl: meson: fix pull enable register calculation
Date: Wed, 26 Dec 2018 17:41:08 -0500 [thread overview]
Message-ID: <20181226224142.150866-1-sashal@kernel.org> (raw)
From: Jerome Brunet <jbrunet@baylibre.com>
[ Upstream commit 614b1868a125a0ba24be08f3a7fa832ddcde6bca ]
We just changed the code so we apply bias disable on the correct
register but forgot to align the register calculation. The result
is that we apply the change on the correct register, but possibly
at the incorrect offset/bit
This went undetected because offsets tends to be the same between
REG_PULL and REG_PULLEN for a given pin the EE controller. This
is not true for the AO controller.
