Messages sorted by: [ date ] [ thread ] [ subject ] [ author ]

As A20 is designed as a pin-compatible upgrade of A10, their pin
controller are very similar, and can share one driver.

Add A20 support to the A10 driver.

Signed-off-by: Icenowy Zheng <icenowy@xxxxxxx>

Changes in v3:
- Enable A10 driver for A20 and disable A20 driver in this commit, in
order to prevent A10 driver from conflicting with A20 driver.
