From 55ed8cded4af6530276b26f567601bed868ae8f5 Mon Sep 17 00:00:00 2001 From: Lee Jackson Date: Wed, 10 Jan 2024 08:52:54 +0800 Subject: [PATCH] drivers: media: imx519: Add V4L2_CID_LINK_FREQ control Add V4L2_CID_LINK_FREQ as a read-only control with a value of 408 Mhz. This will be used by the CFE driver to corretly setup the DPHY timing parameters in the CSI-2 block.
