[PATCH v3] pinctrl: nuvoton: Add NPCM8xx pinctrl driver
Stanley Chu
stanley.chuys at gmail.com
Wed Mar 23 04:06:31 CET 2022
Add Nuvoton BMC NPCM845 Pinmux and Pinconf support.
Signed-off-by: Stanley Chu <yschu at nuvoton.com>
---
v3:
- separate group names and function names in different tables
to allow for adding additional functions
v2:
- drop the WDnRCRB/CORSTCB register access, it is not for
GPIO modules reset control
