Subject: [PATCH 1/5] dt-bindings: power: add Amlogic Everything-Else power domains bindings
Date: Wed, 21 Aug 2019 13:41:17 +0200 [thread overview]
Message-ID: <20190821114121.10430-2-narmstrong@baylibre.com> (raw)
In-Reply-To: <20190821114121.10430-1-narmstrong@baylibre.com>
Add the bindings for the Amlogic Everything-Else power domains,
controlling the Everything-Else peripherals power domains.
The bindings targets the Amlogic G12A and SM1 compatible SoCs,
support for earlier SoCs will be added later.
Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>
