Subject: pinctrl: sunxi: define A31 R_PIO pin functions
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d9d0e1f658afa52c5abfaab112e9b102e15dd971;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

pinctrl: sunxi: define A31 R_PIO pin functions

The A31 SoC provides both PL and PM pio bank through the R_PIO block.

These pins all support gpio function and can bbe assigned to system
peripherals (like TWI, P2WI, JTAG, ...)
