This commit finally adds support for the built in SD/MMC controller in IPQ4019 SoC. Controller is supported by the upstream SDHCI-MSM driver with a minor clock setting patch. Patch is special to the IPQ4019 and cannot be upstreamed. LDO and SDHCI node are upstreamed, and LDO node is awaiting to be accepted. Signed-off-by: Robert Marko <robimarko@gmail.com>

Subject: [PATCH] arm: dts: IPQ4019: add SDHCI VQMMC LDO node
|
|
|
|
Since we now have driver for the SDHCI VQMMC LDO needed
|
|
for I/0 voltage levels lets introduce the necessary node for it.
