- Subject: [PATCH v2 2/2] pinctrl: mediatek: mt7981: add additional emmc groups
- Date: Wed, 17 Jan 2024 15:55:47 +0100
- Message-Id: <[email protected]>
- List-Id: <linux-mediatek.lists.infradead.org>
- Add new emmc groups in the pinctrl driver for the
- MediaTek MT7981 SoC:
- * emmc reset, with pin 15.
- * emmc 4-bit bus-width, with pins 16 to 19, and 24 to 25.
- * emmc 8-bit bus-width, with pins 16 to 25.
- The existing emmc_45 group is kept for legacy reasons, even
- if this is the union of emmc_reset and emmc_8 groups.
