Series ARM: dts: add mmc aliases for Exynos devices | expand

Commit Message

Henrik Grimler Feb. 27, 2023, 7:38 p.m. UTC 
Previously, the mshc0 alias has been necessary so that
MMC_CAP_1_8V_DDR | MMC_CAP_8_BIT_DATA are set for mshc_0/mmc_0.
However, these capabilities should be described in the device tree so
that we do not have to rely on the alias.

The property mmc-ddr-1_8v replaces MMC_CAP_1_8V_DDR, while bus_width =
<8>, which is already set for all the mshc0/mmc0 nodes, replaces
MMC_CAP_8_BIT_DATA.

Also cleanup and sort (but keep status property at top) some of the
nodes while we are modifying them.

Signed-off-by: Henrik Grimler <henrik@grimler.se>

Changes since v2:
* Set mmc-ddr-1_8v in device trees for mshc_0/mmc_0

Thanks for the info! Is this documented somewhere? There seem to be
more nodes with status property first than nodes with status property
last for Exynos devices, so I mistakenly assumed that was the
preferred style.

Will leave cleanup out of next version, thanks for the feedback!
