Subject[PATCH v4 0/8] drm/sun4i: Allwinner MIPI-DSI support

Here is an preliminary version of the MIPI-DSI support for the Allwinner

This controller can be found on a number of recent SoCs, such as the
A31, A33 or the A64.

Given the sparse documentation, there's a number of obscure areas, but
the current implementation has been tested with a 4-lanes DSI panel on
an A33.

The support is a bit rough around the edges at the time, and some artifacts
are still shown on the screen for some reasons. Wider testing with
different display will hopefully nail those down.

This needs the regmap_mmio_attach_clk, on its way to Linus in 4.17.

Let me know what you think,

Changes from v3:
- Rebased on top of current drm-misc-next
- Switched to SPDX license header
- Made the ECC array const
- Split the big DSI patch into two, one to add the DSI driver and one to
add the TCON bits.
- Removed the dithering code
- Changed the DT labels to remove the indices
- Used sleeps instead of delays in the panel driver
- Used the backlight_enable / _disable functions
- Added Chen-Yu's Reviewed-by

Changes from v2:
- Added a ports node under the DSI node
- Changed the huarui panel driver to an ili9881c driver
- Changed the panel vendor to bananapi
- Made the init table static in the panel driver
- Dropped the huarui vendor patch for the DT doc.

Changes from v1:
- Rebased on 4.16-rc1
- Constified a few function arguments and structures
- Reworked the DT binding example a bit
- Reworked the panel driver to check for DSI return codes, and use DCS
helpers when possible
