Subject: [PATCH] arm64: dts: marvell: Enable second SDHCI controller in Armada
|
||||
37xx
|

Origin: https://git.kernel.org/linus/1208d2f0c84120d4e3eb2caf663a9a8b784b38ba

Bug-Debian: https://bugs.debian.org/871049
|
||||
|
||||
The Armada 37xx SoCs has 2 SDHCI interfaces. This patch adds the second
|
||||
one.
|
||||
|
||||
Moreover, the Armada 37xx DB v2 board populates the 2 SDHCI interfaces.
|
||||
|
||||
The second interface is using pluggable module that can either
|
||||
have an SD connector or eMMC on it.
|
||||
This patch adds support for SD module in the device DT.
|
||||
|
||||
[ gregory.clement@free-electrons.com:
|
||||
- Add more detail in commit log
|
||||
- Sort the dt node in address order
|
||||
- Document the SD slot in the dts ]
