Subject: [PATCH 18/18] drm/bridge: cdns-dsi: Don't fail on MIPI_DSI_MODE_VIDEO_BURST
Date: Thu, 20 Mar 2025 18:00:13 +0200 [thread overview]
Message-ID: <20250320-cdns-dsi-impro-v1-18-725277c5f43b@ideasonboard.com> (raw)
In-Reply-To: <20250320-cdns-dsi-impro-v1-0-725277c5f43b@ideasonboard.com>
While the cdns-dsi does not support DSI burst mode, the burst mode is
essentially DSI event mode with more versatile clocking and timings.
Thus cdns-dsi doesn't need to fail if the DSI peripheral driver requests
MIPI_DSI_MODE_VIDEO_BURST.
In my particular use case, this allows the use of ti-sn65dsi83 driver.
