Allwinner H3 SoC features a TV Encoder like the one in Allwinner A13,
which can only output TV Composite signal.
The display pipeline of H3 is also special -- it has two mixers and
two TCONs, of which the connection can be swapped. The TCONs do not
have channel 0 (as they are all connected to internal bridges, TVE
and HDMI TX).
Add support for the display pipeline and the TVE in H3, in order to
make it possible to display something with mainline kernel with H3.
The image quality of TVE is bad, so HDMI is a better output -- this
patchset also prepared the mixers and TCONs for HDMI output, and
the HDMI controller driver is already done by Jernej Skrabec.
So if possible, please apply PATCH 1~5 and 8,9 as soon as possible,
so that Jernej can submit his HDMI patches.
Currently the jack detection feature of the TVE is still not so
clear -- so it's not implemented in this version. Thus the TV
output shouldn't be defaultly enabled now.
Icenowy Zheng (11):
dt-bindings: update the binding for Allwinner H3 TVE support
drm: sun4i: add support for H3 mixers
drm: sun4i: ignore swapped mixer<->tcon connection for DE2
drm: sun4i: add support for H3's TCON0/1
drm: sun4i: add compatible for H3 display engine
drm: sun4i: add color space correction support for DE2 mixer
drm: sun4i: add support for the TV encoder in H3 SoC
clk: sunxi-ng: allow CLK_DE to set CLK_PLL_DE for H3
clk: sunxi-ng: export CLK_PLL_DE for H3
ARM: sun8i: h3: add display engine pipeline for TVE
[DO NOT MERGE] ARM: sun8i: h3: enable TV output on Orange Pi PC
Maxime, could you pick some patches that you think appliable in this
series? (especially PATCH 1, the binding patch)
I think they can be useful.
Thanks!
