Subject: [PATCH 3/3] ARM: dts: exynos: Extend the eMMC node on Arndale Octa
Date: Sat, 9 Mar 2019 16:00:39 +0100 [thread overview]
Message-ID: <20190309150039.8705-3-krzk@kernel.org> (raw)
In-Reply-To: <20190309150039.8705-1-krzk@kernel.org>
Describe properly the MMC0 node (with attached embedded MMC memory) on
Arndale Node by:
1. Adding the regulator for host interface (although it still has to be
"always-on" so the board with Linaro U-Boot will boot;
2. Using "non-removable" instead of "broken-cd" property, because eMMC
is embedded into the board;
3. Adding support for HS200 v1.8 to indicate support in host controller
although this has no practical effect (embedded memory does not
support it).
