Subject: [PATCH v4] arm64: dts: rockchip: add EEPROM node for NanoPi R4S
Date: Tue, 22 Jun 2021 11:45:05 +0800	[thread overview]
Message-ID: <20210622034505.18824-1-cnsztl@gmail.com> (raw)

NanoPi R4S has a EEPROM attached to the 2nd I2C bus (U92), which
stores the MAC address.

Changes in v4:
- Fixed typo error: `nvmem-cells-names` -> `nvmem-cell-names`

Changes in v3:
- Added address-cells and size-cells

Changes in v2:
- Added the size of EEPROM
- Added `mac-address` cell to pass the MAC address to kernel
- Removed `read-only` property in EEPROM node
