From bdb55fb216c5d7eb6a7c5b4ab6c9984be75865ff Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Wed, 15 Feb 2023 23:29:59 +0100 Subject: [PATCH] media: i2c: imx290: VMAX is mode dependent The default VMAX for 60fps in 720p mode is 750 according to the datasheet, however the driver always left it at 1125 thereby stopping 60fps being achieved. Make VMAX (and therefore V4L2_CID_VBLANK) mode dependent so that 720p60 can be achieved.
