Date: Wed, 22 Sep 2021 21:13:13 +0100 [thread overview]
Message-ID: <20210922201314.3205674-1-kieran.bingham@ideasonboard.com> (raw)
Add support for SW47, SW48 and SW49 via "gpio-keys" on the R-Car V3U
Falcon board.

Apologies, I sent out v1 with locally staged changes that didn't get sqaushed
in.
v2:
- add wakeup-source to key-1
- make line ordering consistent across each key
