Subject: [PATCH v3 2/2] dt-bindings: gpio: Add bindings for NXP PCA9570
Date: Wed,  1 Jul 2020 01:09:34 +0900
Message-ID: <20200630160934.1197066-1-mans0n@gorani.run> (raw)
In-Reply-To: <20200630160736.1196697-1-mans0n@gorani.run>

This patch adds device tree bindings for the NXP PCA9570,
a 4-bit I2C GPO expander.

Signed-off-by: Sungbo Eo <mans0n@gorani.run>

v3:
* fixed dt_binding_check error

v2:
I don't feel I can really maintain this driver, but it seems all yaml docs
have a maintainers field so I just added it...
