Subject: [PATCH 12/12] arm64: dts: marvell: armada-3720-espressobin: Add vqmmc
|
||
|
|
regulator for SD slot
|
||
|
|
|
||
|
|
By adding this regulator, the SD cards are usable at higher speed
|
||
|
|
protocols such as SDR104.
|
||
|
|
|
||
|
|
This patch was tested with an SDHC card compatible with UHS-I.
