commit a4769905f0ae32cae4f096f646ab03b8b4794c74 upstream.

YUV444 and YVU444 are planar formats, but HW format RGB888 is packed.
This means that those two mappings were never correct. Remove them.

commit 20896ef137340e9426cf322606f764452f5eb960 upstream.

DE2 VI layer doesn't support blending which means alpha channel is
ignored. Replace all formats with alpha with "don't care" (X) channel.

commit 169ca4b38932112e8b2ee8baef9cea44678625b3 upstream.

DE3 VI layers support alpha blending, but DE2 VI layers do not.
Additionally, DE3 VI layers support 10-bit RGB and YUV formats.

Make a separate list for DE3.

commit cf913e9683273f2640501094fa63a67e29f437b3 upstream.

This reverts commit 9db9c0cf5895e4ddde2814360cae7bea9282edd2.

Setting mode_config.allow_fb_modifiers manually is completely
unnecessary. It is set automatically by drm_universal_plane_init() based
on the fact if modifier list is provided or not. Even more, it breaks
DE2 and DE3 as they don't support any modifiers beside linear. Modifiers
aware applications can be confused by provided empty modifier list - at
least linear modifier should be included, but it's not for DE2 and DE3.

<title>drm/sun4i: tcon: Set RGB DCLK min. divider based on hardware model</title>

<id>urn:sha1:4396393fb96449c56423fb4b351f76e45a6bcaf6</id>
<content type='text'>
In commit 0b8e7bbde5e7 ("drm/sun4i: tcon: Set min division of TCON0_DCLK
to 1.") it was assumed that all TCON variants support a minimum divider
of 1 if only DCLK was used.

However, the oldest generation of hardware only supports minimum divider
of 4 if only DCLK is used. If a divider of 1 was used on this old
hardware, some scrolling artifact would appear. A divider of 2 seemed
OK, but a divider of 3 had artifacts as well.

Set the minimum divider when outputing to parallel RGB based on the
hardware model, with a minimum of 4 for the oldest (A10/A10s/A13/A20)
hardware, and a minimum of 1 for the rest. A value is not set for the
TCON variants lacking channel 0.

This fixes the scrolling artifacts seen on my A13 tablet.

<content type='text'>
When the HDMI unbinds drm_connector_cleanup() and drm_encoder_cleanup()
are called. This also happens when the connector and the encoder are
destroyed. This double call triggers a NULL pointer exception.

The patch fixes this by removing the cleanup calls in the unbind
function.

<content type='text'>
The datasheet of V3s (and various other chips) wrote
that TCON0_DCLK_DIV can be &gt;= 1 if only dclk is used,
and must &gt;= 6 if dclk1 or dclk2 is used. As currently
neither dclk1 nor dclk2 is used (no writes to these
bits), let's set minimal division to 1.

If this minimal division is 6, some common dot clock
frequencies can't be produced (e.g. 30MHz will not be
possible and will fallback to 25MHz), which is
obviously not an expected behaviour.

The DSI driver misinterpreted the vbp term from the BSP code to refer
only to the backporch, when in fact it was backporch + sync. Thus the
driver incorrectly used the vertical front porch plus sync in its
calculation of the DRQ set bit value, when it should not have included
the sync timing.

Including additional sync timings leads to flip_done timed out as:
