[PATCH 0/1] ARM: meson8b-mxq: better support for the TRONFY MXQ

[Martin Blumenstingl]

A while ago a user asked on #linux-amlogic about the state of the
TRONFY MXQ in mainline. I did some research (mainly downloading an
Android firmware image for that device and looking at the .dtb) and
updated the mainline .dts accordingly.

I kept this patch in my tree but didn't hear back from anyone with one
of these boards (who could actually test my patch). That was until
today where I got the following message on IRC:
  any plans to submit your latest own version of the meson8b mxq dtb
  to mainline? it works really well for me and the one in mainline is
  too simple to be usedful ...

Thus I believe that this patch is finally ready for being included
upstream!

[PATCH 1/1] ARM: dts: meson8b: mxq: improve support for the TRONFY MXQ S805

[Martin Blumenstingl]

The TRONFY MXQ comes with either 1GB or 2GB RAM.

Both variants share (like most boards based on Amlogic reference
designs):
- 10/100 PHY (IC Plus IP101GR) with GPIOH_4 being the reset line and
  GPIOH_3 the interrupt line
- SD card slot with the card detection GPIO at CARD_6
- VCCK is generated by PWM_C with a period of 1148ns and XTAL as input
  clock
- USB OTG exposed on one of the USB-A connectors
- 4-port USB hub with 3 ports exposed to the outside

There seem the multiple board revision out there according to various
forum posts:
- storage: eMMC or NAND flash
- wifi: Ampak AP6210 or Realtek 8189

Add support for the following functionality:
- SoC temperature (hwmon)
- changing the CPU voltage
- Ethernet connectivity
- SD card
- USB

Any chance of getting a Tested-by: from that IRC user on the patch?

I CC'ed hexdump0815 so I'm hoping that he can send a Tested-by (he
left IRC before I could reply to him)

BEFORE (no patches from this series applied):
the mxq device was not really useable with the old mainline dtb as
most peripeherals were not supported

AFTER (the patch applied):
the rresulting dtb works perfectly fine with my mxq device and all
mentioned supported functions work as expected

best wishes - hexdump

Thanks for testing.

Queued for v5,3,
