Subject: [PATCH AUTOSEL 5.3 26/81] arm64: dts: rockchip: fix RockPro64 sdhci settings
Date: Wed, 30 Oct 2019 11:48:32 -0400 [thread overview]
Message-ID: <20191030154928.9432-26-sashal@kernel.org> (raw)
In-Reply-To: <20191030154928.9432-1-sashal@kernel.org>
From: Soeren Moch <smoch@web.de>
[ Upstream commit 2558b3b1b11a1b32b336be2dd0aabfa6d35ddcb5 ]
The RockPro64 schematics [1], [2] show that the rk3399 EMMC_STRB pin is
connected to the RESET pin instead of the DATA_STROBE pin of the eMMC module.
So the data strobe cannot be used for its intended purpose on this board,
and so the HS400 eMMC mode is not functional. Limit the controller to HS200.
