2017-10-04[media] media: ov5670: Fix not streaming issue after resumeChiranjeevi Rapolu
Previously, the sensor was not streaming after resume from suspend, i.e. on S0->S3->S0 transition. Due to this, camera app preview appeared as stuck. Now, handle streaming state correctly in case of suspend-resume.

2017-10-04[media] media: ov5670: Use recommended black level and output biasChiranjeevi Rapolu
Previously, images were relatively darker due to non-optimal settings for black target level and bias. Now, use recommended settings for black target level and output bias as default values. The same default settings apply to all the resolutions. Given these recommeneded settings do not change dynamically, add these to existing mode register settings.

2017-08-20media: ov5670: Limit vblank to permissible rangeChiranjeevi Rapolu
Previously, vblank range given to user was too big, falling outside of permissible range for a given resolution. Sometimes, too low vblank resulted in errors. Now, limit vblank to only permissible range for a given resolution. This change limits lower-bounds of vblank, doesn't affect upper bounds.

2017-08-20media: ov5670: Fix incorrect frame timing reported to userChiranjeevi Rapolu
Previously, pixel-rate/(pixels-per-line * lines-per-frame) was yielding incorrect frame timing for the user. OV sensor is using internal timing and this requires conversion (internal timing -> PPL) for correct HBLANK calculation. Now, change pixels-per-line domain from internal sensor clock to pixels domain. Set HBLANK read-only because fixed PPL is used for all resolutions. And, use more accurate link-frequency 422.4MHz instead of rounding down to 420MHz.
