This includes the "Alta" and "Solitude" boards, the latter of which I also introduce a device package for in a later patch. It should be easy to introduce support for the former, but I don't have the hardware to test that on. The two new patches have been merged and will be included in Linux 6.7 as I understand.

Subject: [PATCH 1/4] ARM64: dts: meson-gxl: add support for the Xiaomi Mi Box
|
|
3
|
|
|
|
The Xiaomi Mi Box 3 is a TV box based on the Amlogic S905X chipset.
|
|
There are two variants:
|
|
- 2 GiB of DDR3 memory
|
|
- 8 GB eMMC flash
|
|
|
|
Both variants come with:
|
|
- 802.11a/b/g/n/ac wifi (BCM4345)
|
|
- HDMI and AV (CVBS) output
|
|
- 1x USB (utilizing both USB ports provided by the SoC)
|
|
|
|
The board seems to be very similar to the P212 reference
|
|
boards, which is why it includes meson-gxl-s905x-p212.dtsi:
