Subject: [PATCH v2 1/2] dt-bindings: etnaviv: add slave interface clock
Date: Wed, 24 Jan 2018 16:37:10 +0100	[thread overview]
Message-ID: <20180124153711.22049-1-l.stach@pengutronix.de> (raw)

Newer GPU cores added a new clock input, which allows to gate the slave (AHB)
interface independently from other parts of the GPU. Add it to the supported
clocks.

Signed-off-by: Lucas Stach <l.stach@pengutronix.de>

v2: State when this clock is required.
