Subject: [RFC PATCH 02/13] dt-bindings: msm/dsi: Document Display Stream Compression (DSC) parameters
Date: Fri, 21 May 2021 18:19:31 +0530	[thread overview]
Message-ID: <20210521124946.3617862-3-vkoul@kernel.org> (raw)
In-Reply-To: <20210521124946.3617862-1-vkoul@kernel.org>

DSC enables streams to be compressed before we send to panel. This
requires DSC enabled encoder and a panel to be present. So we add this
information in board DTS and find if DSC can be enabled and the
parameters required to configure DSC are added to binding document along
with example
