-Subject: [PATCH] media: i2c: imx290: Fix the pixel rate at 148.5Mpix/s
-
-Whilst the datasheet lists the link frequency changing between
-1080p and 720p modes, reality is that with the default blanking
-we have
-(1920 + 280) * (1080 + 45) * 60fps = 148.5MPix/s
-and
-(1280 + 2020) * (720 + 30) * 60fps = 148.5MPix/s
-and this reflects reality whether in 10 or 12 bit readout modes.
-
-How this relates to link frequency is unclear as it differs
-from the datasheet, but all exposure and frame rate calcs need
-the pixel rate to be correct, so make it so.
