[PATCH v2 08/13] pinctrl: Add sun50i-a64 pinctrl driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



sunxi pinctrl driver, adapted from Linux, is split in two parts:
 - pinctrl-sunxi.c that implements gpio, pinctrl and pinmux functions
 - pinctrl-sun50i-a64.c that declare sun50i pins and their functions,
   as such information are not described in device-tree. This file
   only require minor adaptations and be easily copied from Linux.

The pin functions are needed for uart, SD/MMC, and likely for other
controllers too.
