The Amlogic S905, also known as Meson GXBB in the Linux kernel, is a high-end media player SoC mainly used in Android set top boxes. It's capable of hardware decoding up to 4K@60fps, for multiple formats including H.264, AVS+, and 10-bit, and part of the S9 family of Amlogic chipsets.
There's also the Amlogic S905-H SoC, which merely just includes Dolby licenses.

Status
IR RX
Works. Be sure to include the right IR decoders into your kernel (e.g. NEC on Videostrong KII Pro (videostrong-kii-pro)), but otherwise doesn't require much configuration.
Audio
Works. Requires a device tree patch on the Videostrong KII Pro (videostrong-kii-pro), that adds the appropriate nodes (else the card is never pobed) which is slowly making its way upstream. HDMI audio works, but S/PDIF is untested.
Hardware decoding and encoding
The Amlogic S905(-H) supports hardware decoding up to 4K@60fps, but in the mainline kernel it's limited to 1080p. Downstream kernels relied on lengthy hacks to get it working up to 4K, and thus they were not included in the mainline kernel (to their defense Amlogic did successfully enable 4K playback on 3.x kernels).

Does the S905(-H) have the ability to sleep? |
DVB
Needs a demux driver.
HDMI
Works.
USB-A
Works.
