Subject: [PATCH 142/224] mmc: dt-bindings: Add reg/source_cg/latch-ck for
|
|
Mediatek MMC bindings
|
|
|
|
Change the comptiable for support of multi-platform
|
|
Make compatible explicit, as MMC host of mt8173 has difference with
|
|
mt8135(mt8173 supports hs400 and hs400_tune),so that need separate
|
|
mt8173/mt8135 compatible name.
|
|
Add description for reg
|
|
Add description for source_cg
|
|
Add description for mediatek,latch-ck
|
|
Note that source_cg and mediatek,latch-ck are optional for some projects,
|
|
eg, MT2701 do not have source_cg, and MT2712 do not need
|
|
mediatek,latch-ck
