Subject: [PATCH v1 4/4] arm64: dts: sdm845: Add zap shader region for GPU
Date: Tue, 12 Mar 2019 12:13:42 -0600	[thread overview]
Message-ID: <1552414422-9568-5-git-send-email-jcrouse@codeaurora.org> (raw)
In-Reply-To: <1552414422-9568-1-git-send-email-jcrouse-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>

Some Adreno GPU targets require a special zap shader to bring the GPU
out of secure mode. Define a region to allocate and store the zap
shader.
