Hi Yifeng, Just a few more comments (part 1). About the name of the dts patches. Currently this is used: Subject [PATCH v6 6/8] arm: dts: rockchip: Add nfc dts for RV1108 SOC Add nfc(nand flash controller) node for RV1108 Soc. Dts is more file related. The patch adds a node, so maybe change it to: Subject [PATCH v7 6/8] arm: dts: rockchip: Add nfc node for RV1108 SoC Add NAND FLASH Controller(NFC) node for RV1108 SoC.
