Subject: [PATCH v5 6/6] ARM: dts: sun8i: s3: add devicetree for Lichee zero plus w/ S3
Date: Sun, 28 Jul 2019 11:12:27 +0800	[thread overview]
Message-ID: <20190728031227.49140-7-icenowy@aosc.io> (raw)
In-Reply-To: <20190728031227.49140-1-icenowy@aosc.io>

Lichee zero plus is a core board made by Sipeed, which includes on-board
TF slot or SMT SD NAND, and optional SPI NOR or eMMC, a UART debug
header, a microUSB slot and a gold finger connector for expansion. It
can use either Sochip S3 or Allwinner S3L SoC.

Add the basic device tree for the core board, w/o optional onboard
storage, and with S3 SoC.

Signed-off-by: Icenowy Zheng <icenowy@aosc.io>

Changes in v5:
- Added missing compatible string.
- Set default USB role to "peripheral".
- Switch to use V3 DTSI.

No changes in v4.

Changes in v3:
- Drop common regulator DTSI usage and added vcc3v3 regulator.

Patch introduced in v2.
