Subject: [PATCH v6 0/6] Add DSC support to DSI video panel

This is follow up update to Jonathan's patch set.

Changes vs V5:
- Add hardware version check for compression bit change in cfg2 register

Changes vs V4:
- Polish width calculation with helper function
- Split cfg2 compression bit into another patch

Changes vs V3:
- Rebase to latest msm-next-lumag branch.
- Drop the slice_per_pkt change as it does impact basic DSC feature.
- Remove change in generated dsi header
- update DSC compressed width calculation with bpp and bpc
- split wide bus impact on width into another patch
- rename patch tile of VIDEO_COMPRESSION_MODE_CTRL_WC change
- Polish warning usage
- Add tags from reviewers

Changes vs V2:
- Drop the INTF_CFG2_DATA_HCTL_EN change as it is handled in
latest mainline code.
- Drop the bonded DSI patch as I do not have device to test it.
- Address comments from version 2.
