From 295786e53516ba1792b5ff1deb9dfffff4040255 Mon Sep 17 00:00:00 2001 From: Daniel Scally Date: Tue, 23 Nov 2021 01:00:11 +0100 Subject: [PATCH] media: i2c: Update HTS values in ov8865 The HTS values for some of the modes in the ov8865 driver are a bit unusual, coming in lower than the output_size_x is set to. It seems like they might be calculated to fit the desired framerate into a configuration with just two data lanes. To bring this more in line with expected behaviour, raise the HTS values above the output_size_x. The corollary of that change is that the hardcoded frame intervals against the modes no longer make sense, so remove those entirely. Update the .g/s_frame_interval() callbacks to calculate the frame interval based on the current mode and the vblank and hblank settings. The implementation of the .enum_frame_interval() callback is no longer suitable since the possible frame rate is now a continuous range depending on the vblank control setting, so remove that callback entirely.
