This series adds support for several popular Amlogic S905X3 (SM1) Android Set-Top Box devices. Like most Android box devices, they ship in variants with multiple RAM, eMMC, WiFi and BT configurations. RAM and eMMC are not something we need to consider to get a working boot, but we do need to get the correct connectivity spec. Broadly speaking we see boxes with Higher and Lower spec connectivity; High spec is Gigabit Ethernet and Faster dual antennna WiFi, and Lower spec is Megabit Ethernet and a single antenna. In some low-end boxes BT is ommitted. The main reason for the RFC tag is to solicit feedback on the choice of the -100 and -1000 suffixes which are used to distinguish between devices with 10/100 Mbit (Internal PHY) or 10/100/1000 Gbit (External PHY) NIC configurations; which is important to get correct else the box will have no connectivity. I'm not a big fan of the suffixes, but earlier versions where I used -int/-ext and -mbit/-gbit resulted in users having no idea what the difference was. I'd like to informally establish a convention for this naming before doing similar things with some S905X2 devices. NB: At the current time the Realtek 8822CS and MT7668 WiFi/BT chips we have seen on 'AIR' devices are not supported in the kernel so these are deliberately ommitted. The H96-Max uses a conventional Broadcom module so has more complete support. I'm also still exploring / learning about alsa userspace configuration so for now the boxes have simple HDMI audio support; wiring up the Headphone socket will be done at a later date.
