Subject: [PATCH v2 11/11] drm/msm/dsi: Pass DSC params to drm_panel
Date: Thu, 7 Oct 2021 12:39:00 +0530 [thread overview]
Message-ID: <20211007070900.456044-12-vkoul@kernel.org> (raw)
In-Reply-To: <20211007070900.456044-1-vkoul@kernel.org>
When DSC is enabled, we need to pass the DSC parameters to panel driver
as well, so add a dsc parameter in panel and set it when DSC is enabled
