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

Commit Message

Henrik Grimler March 16, 2023, 9:15 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 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

Why you do not remove Exynos3250 aliases?

Thanks for spotting that, seems I accidentally dropped removal when
going from v3 to v4.  Will remove them again in next version, and drop
Marek's test tag since rinato is one of the devices he tests (or used
to test).
