From de39557748cf4e8510639fc9e713ecb958abfa48 Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Wed, 15 Feb 2023 23:29:55 +0100 Subject: [PATCH] media: i2c: imx290: Support 60fps in 2 lane operation Commit "97589ad61c73 media: i2c: imx290: Add support for 2 data lanes" added support for running in two lane mode (instead of 4), but without changing the link frequency that resulted in a max of 30fps. Commit "98e0500eadb7 media: i2c: imx290: Add configurable link frequency and pixel rate" then doubled the link frequency when in 2 lane mode, but didn't undo the correction for running at only 30fps, just extending horizontal blanking instead. Remove the 30fps limit on 2 lane by correcting the register config in accordance with the datasheet for 60fps operation over 2 lanes.
