Date: Fri, 6 Jan 2023 16:28:43 +0100 [thread overview]
Message-ID: <20230106152845.88717-4-linux@fw-web.de> (raw)
In-Reply-To: <20230106152845.88717-1-linux@fw-web.de>
From: Sam Shih <sam.shih@mediatek.com>

Signed-off-by: Sam Shih <sam.shih@mediatek.com>
Signed-off-by: Frank Wunderlich <frank-w@public-files.de>
---
v2:
- update mmc-node because clocks changed
v3:
- fix pullups/pulldowns for mt7986a-rfb to have generic bias-pull-*
v6:
- add 3v3 regulator in mt7986a-rfb (was in usb patch before)
- dropped AngeloGioacchino RB because of this change

Subject: [PATCH v9 3/5] arm64: dts: mt7986: add mmc related device nodes
Date: Fri, 6 Jan 2023 16:28:43 +0100 [thread overview]
Message-ID: <20230106152845.88717-4-linux@fw-web.de> (raw)
In-Reply-To: <20230106152845.88717-1-linux@fw-web.de>
From: Sam Shih <sam.shih@mediatek.com>
This patch adds mmc support for MT7986.
Signed-off-by: Sam Shih <sam.shih@mediatek.com>
Signed-off-by: Frank Wunderlich <frank-w@public-files.de>
---
v2:
- update mmc-node because clocks changed
v3:
- fix pullups/pulldowns for mt7986a-rfb to have generic bias-pull-*
v6:
- add 3v3 regulator in mt7986a-rfb (was in usb patch before)
- dropped AngeloGioacchino RB because of this change
