Subject: [PATCH AUTOSEL 4.14 04/36] ARM: dts: dra74x: Fix iodelay configuration for mmc3
Date: Wed, 4 Sep 2019 12:00:50 -0400 [thread overview]
Message-ID: <20190904160122.4179-4-sashal@kernel.org> (raw)
In-Reply-To: <20190904160122.4179-1-sashal@kernel.org>
From: Faiz Abbas <faiz_abbas@ti.com>
[ Upstream commit 07f9a8be66a9bd86f9eaedf8f8aeb416195adab8 ]
According to the latest am572x[1] and dra74x[2] data manuals, mmc3
default, hs, sdr12 and sdr25 modes use iodelay values given in
MMC3_MANUAL1. Set the MODE_SELECT bit for these so that manual mode is
selected and correct iodelay values can be configured.
