Subject: [PATCH] arm64: dts: allwinner: Add GPU operating points for H6
Date: Wed, 29 May 2019 17:32:55 +0200	[thread overview]
Message-ID: <20190529153255.40038-1-tomeu.vizoso@collabora.com> (raw)
In-Reply-To: <20190521161102.29620-1-peron.clem@gmail.com>

The GPU driver needs them to change the clock frequency and regulator
voltage depending on the load.

Signed-off-by: Tomeu Vizoso <tomeu.vizoso@collabora.com>

Feel free to pick up this patch if you are going to keep pushing this
series forward.

Thanks,

Tomeu
