Subject: [PATCH v2 2/2] arm64: dts: allwinner: h313: Add Amediatech X96Q
From: "J. Neuschäfer" <j.ne@...teo.net>
The X96Q is a set-top box with an H313 SoC, AXP305 PMIC, 1 or 2 GiB RAM,
8 or 16 GiB eMMC flash, 2x USB A, Micro-SD, HDMI, Ethernet, audio/video
output, and infrared input.
https://x96mini.com/products/x96q-tv-box-android-10-set-top-box
Tested, works:
- debug UART
- status LED
- USB ports in host mode
- MicroSD
- eMMC
- recovery button hidden behind audio/video port
- analog audio (line out)
Does not work:
- Ethernet (requires AC200 MFD/EPHY driver)
- WLAN (requires out-of-tree XRadio driver)
- analog video output (requires AC200 driver)
- HDMI audio/video output
Untested:
- "OTG" USB port in device mode
- built-in IR receiver
- external IR receiver

v2:
- remove mmc aliases, &mmc0/max-frequency property (Andre Przywara)
- document reason for &mmc2/max-frequency property
- clean up mmc-releated comments (Andre Przywara)
- rename dcdcd regulator to vdd-dram, because it's the only source of
1.5V (needed by the Micron MT41J256M4 DDR3 RAM), and the system halts
when it's turned off.
