[PATCH v5 1/2] ARM: dts: exynos: replace mshc0 alias with mmc-ddr-1_8v property

Henrik Grimler henrik at grimler.se
Thu Mar 16 14:15:57 PDT 2023 

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 drop other mshc aliases as they are not needed.

Changes since v4:
* Do not set mmc-ddr-1_8v for sdhci_0 on Exynos 4210,
  following Marek's tests

Changes since v3:
* Drop attempt at node sorting/cleaning
* Move two mmc alias additions to the other patch
* Update commit message

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