Therefore both display_h_end and display_v_end need to be adjusted accordingly. However current implementation has only display_h_end adjusted.

Changes are added to program this register correctly based on the target. DATA_HCTL_EN in INTF_CONFIG2 register allows data to be transferred at a different rate than video timing. When this is set, the number of data per line follows DISPLAY_DATA_HCTL register value. This change adds support to program these registers for sc7280 target.

This will reduce cpu wakeups and help in power saving. To enable vblank_disable_immediate flag the underlying KMS driver needs to support high precision vblank timestamping and also a reliable way of providing vblank counter which is incrementing at the leading edge of vblank. This patch also brings in changes to support vblank_disable_immediate requirement in dpu driver. Changes in v1: - Specify reason to add vblank timestamp support. (Rob). - Add changes to provide vblank counter from dpu driver. Changes in v2: - Fix warn stack reported by Rob Clark with v2 patch. Changes in v3: - Move back to HW frame counter (Rob). Changes in v4: - Frame count mismatch was causing a DRM WARN stack spew. DPU HW will increment the frame count at the end of the sync, where as vblank will be triggered at the fetch_start counter which is calculated as v_total - vfp. This is to start fetching early for panels with low vbp w.r.t hw latency lines. Add logic to detect the line count if it falls between vactive and v_total then return incremented frame count value.

This also adds separate feature bits for INTF (based on downstream) instead of using CTL feature bit for it, and removes the unnecessary NULL check in the added bind_pingpong_blk function.
