ARM: dts: exynos: Extend the eMMC node on Arndale Octa (9a435fb2) · Commits · 戴 / test

Describe properly the MMC0 node (with attached embedded MMC memory) on Arndale Octa 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 properly); 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 such support in host controller although this has no practical effect (embedded memory does not support it). Signed-off-by:
