so hmm the csi driver patches which are posted, is that code also usable for the H3?
<wens>
probably?
<plaes>
jelle: see Maxime's reply
<mripard>
the controllers are very similar
<mripard>
so it might need a few adjustments, but they should be really minor
<jelle>
good to hear :)

such as missing interface types

oh shitty design which wastes a lot of functions
<MoeIcenowy>
the most significant advantage of H3 is multiple USB controller
<MoeIcenowy>
then GbE
<MoeIcenowy>
but using a Zero W design lost these two advantages easily

i have a lime2 with the 4.3 LCD panel

i am working on maxime's for-drm tree and added plaes patches for the new clocks

rgb (lcd panel) is tied to whatever tcon you connect it to
<wens>
and you can forget about RGB from tv encoders for now
<wens>
it's not supported yet
<Net147>
I guess it is just making sure the inputs don't conflict...

oliv3r: there is no register field for "rgb" panel outputs
<wens>
the tcon mux register only mux-demuxes tcon channel 1 outputs to the hdmi and tv encoders
<oliv3r>
wens: ah check
<oliv3r>
wens: last week I spent the night reading the datasheet (which is a pain in itself) but I had the impression you could mux anything from anything
<oliv3r>
so LVDS and RGB are thus always bound to tcon0 (where 1 is left and 0 is right)
<wens>
both tcons have panel outputs
<wens>
check the soc datasheet

Does anyone have one of the Sunvell R69 TV media boxes with H2 Allwinner SoC? I really don't see any repositories with H2 support. Everything is H2+ or H3, but as far as I understood they should be really similar. So it would be nice to try to port linux and u-boot for this board, but I'm just wondering if it has UART.
