Subject: [PATCH] soc: imx: imx8mp-blk-ctrl: set HDMI LCDIF panic read hurry level
Date: Mon, 9 Jan 2023 17:12:42 +0100 [thread overview]
Message-ID: <20230109161242.54620-1-l.stach@pengutronix.de> (raw)
Same as done for both LCDIF interfaces in the MEDIA domain, set
the panic priority of the LCDIF instance in the HDMI domain to
the maximium NoC priority of 7 to minimize chances of display
