Although on the schematics of Insignal Arndale Octa board the
PVDD_MIFS_1V1 (ldo23) and PVDD_G3DS_1V0 (ldo27) are marked as 1.2 V, the
vendor v3.4 Android kernel sets them lower. Also name suggests that
they should work on 1.1 V and 1.0 V respectively, not 1.2 V.

The Exynos5420's Mobile Storage Host supports SD cards in UHS-I standard
(SD specification v3.0), with 1.8 V signaling in SD UHS DDR50. Adjust
the regulator and add necessary capability properties. Change the SDR
and DDR timings to match values in Insignal v3.4 Android kernel.
Tested with SD UHS-I card in SD UHS DDR50 mode.

* [PATCH 3/3] ARM: dts: exynos: Extend the eMMC node on Arndale Octa

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).
