[PATCH v2 0/3] Misc fixes up for MT7623 mmc

[sean.wang]

From: Sean Wang <sean.wang@mediatek.com>

Changes since v1:
- add tag from the feedback of v1
- enhance dt-binding documentation

Just add some fixes up for the current MT7623 support

Patch 1) complement the missing dt-bindings definitions
Patch 2) pick up the proper falling back as patch 1 defines.
Patch 3) SD-card detection issue caused by the wrong polarity is being fixed up

Sean Wang (3):
  mmc: dt-bindings: add mmc support to MT7623 SoC
  arm: dts: mt7623: update mmc related nodes with the appropriate
    fallback
  arm: dts: mt7623: fix card detection issue on bananapi-r2

[PATCH v2 2/3] arm: dts: mt7623: update mmc related nodes with the appropriate fallback

[sean.wang]

From: Sean Wang <sean.wang@mediatek.com>

The current mmc related nodes should be falling back to MT2701
as the dt-binding defines and which has more appropriate setup
for MT7623.

[PATCH v2 3/3] arm: dts: mt7623: fix card detection issue on bananapi-r2

[sean.wang]

From: Sean Wang <sean.wang@mediatek.com>

Fix that bananapi-r2 booting from SD-card would fail since incorrect
polarity is applied to the previous setup with GPIO_ACTIVE_HIGH.

Are you fine to take this patch through your branch, or shall I take it through
mine?

@Sean it seems you forgot to send this patch to Ulf as well. In the future
please take care to send the patch to all relevant people and mailinglist.

Thanks,
Matthias
