xiaomi-aries: initial device support with MoKee kernel

The last merge request of this device was !168 (closed)

Finally got display working, but it's based on MoKee kernel which is also hosted on GitHub by community.

So what works:

• USB Networking
• Flashing
• Touchscreen
• Display
• Weston with Xwayland

And I got a problem. The device boots and shows the splash screen properly, after about 3 sec the screen went black. I had to echo 127 > /sys/devices/i2c-0/0-0038/leds/lm3530-backlight/brightness to make the backlight work, even though the value of it was already 127

Changes look good, thank you very much for this port @Lwrless!

(Also the flash mode image looks cute, thanks for making a photo of that )

And I got a problem. The device boots and shows the splash screen properly, after about 3 sec the screen went black. I had to echo 127 > /sys/devices/i2c-0/0-0038/leds/lm3530-backlight/brightness to make the backlight work, even though the value of it was already 127

You could try if this gets fixed by msm-fb-refresher, or write a similar tool / make it more generic to write this brightness parameter too. Or you could directly fix it in your kernel (search for lm3530-backlight, maybe there is a timer that turns it off automatically?).

And of course there's also mainlining as highest effort, but best solution.
