Subject: [PATCH 3/3] dt-bindings: etnaviv: add slave interface clock
Date: Fri, 19 Jan 2018 13:06:34 +0100 [thread overview]
Message-ID: <20180119120634.22856-3-l.stach@pengutronix.de> (raw)
In-Reply-To: <20180119120634.22856-1-l.stach-bIcnvbaLZ9MEGnE8C9+IrQ@public.gmane.org>
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.
