Subject: [PATCH v2 1/2] arm64: dts: exynos: drop mshc aliases
Date: Wed, 15 Mar 2023 22:28:13 +0100	[thread overview]
Message-ID: <20230315212814.15908-2-henrik@grimler.se> (raw)
In-Reply-To: <20230315212814.15908-1-henrik@grimler.se>

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.

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

Changes since v1:
* Add mmc-ddr-1_8v property so that capabilities stays the same
  when mshc0 alias is removed
