Subject: [PATCH v5 6/6] arm64: dts: allwinner: Add mali GPU supply for H6 boards
Date: Fri, 17 May 2019 20:46:59 +0200	[thread overview]
Message-ID: <20190517184659.18828-7-peron.clem@gmail.com> (raw)
In-Reply-To: <20190517184659.18828-1-peron.clem@gmail.com>

Enable and add supply to the Mali GPU node on all the
H6 boards.

Regarding the datasheet the maximum time for supply to reach
its voltage is 32ms.
