I suppose the first thing to do is try to get in touch with whomever
might be working on this at the moment or in the (recent) past.

Look at the MAINTAINERS file, to find "official" maintainers and reviewers.

The baylibre team seems to be handling some of the mainlining effort,
so perhaps they are in a good position to provide relevant information.

There's also a specific mailing list: linux-amlogic@lists.infradead.org

Regards.

The #linux-amlogic IRC channel on freenode is a good place to start as any.
AFAICT, most of the active community contributors hang out there.

Hi Daniel,

DRM Display support for the S905Y2 will be available in Linux v5.2,
but necessary devices (mmc, sdcard, sdio, ethernet) will land in Linux v5.3-rc1
in allmost 4weeks, but you can check the integ tree to test these features as
described on http://linux-meson.com/doku.php#development_resources :
https://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-amlogic.git/log/?h=v5.3/integ

Video decoder support for S905Y2 is in the work, bit we mainly focused to have
the bare minimum driver being merged for S905/S905X/S912 before pushing more
complex decoder and new SoCs support :
https://github.com/Elyotna/linux/tree/mjourdan/media/v5.2/aml/vdec

BTW, you are very welcome !

As Chen-Yu Tsai said, we idle on #linux-amlogic IRC channel on freenode and
activaly use the linux-amlogic@lists.infradead.org ML.

You can also join the u-boot-amlogic@groups.io ML if you are interested in
mainline U-Boot dev for amlogic SoCs.
