ARM: davinci: da850: add pinctrl driver DT entries (1faaba3d) · Commits · 戴 / test

For DT, DaVinci platform can use pinctrl-single driver for handling padconf registers. Enable PINCTRL Kconfig for MACH_DA8XX_DT platform. Add required pinctrl DT entries in da850 dts file. Test procedure 1)Populate DT file with NAND node information. 2)Populate board DT file with pinmux information for NAND. 3)Boot and confirm NAND is detected by the kernel. 4)cat /proc/mtd to show partitions.
