[PATCH 0/3] arm64: dts: allwinner: Add Transpeed 8K618-T TV box

[Andre Przywara]

The Transpeed 8K618-T is one example of various cheap Chinese TV boxes
using the Allwinner H618 SoC. It comes with up to 4GB DRAM and up to
128GB eMMC flash, plus the usual HDMI, 100Mbit Ethernet, WiFi/BT and
dual USB ports, not to forget the mandatory microSD card slot.
More details: https://linux-sunxi.org/Transpeed_8K618-T

Ethernet relies on the yet unsupported integrated PHY, and the HDMI
output is similarly not yet supported, but patches exist that await
polishing for mainline submission.
Meanwhile USB and eMMC plus SD card work, so you can hook up an USB
Ethernet or WiFi adapter to get things going.

This series is the usual trilogy of DT support patches: adding the vendor
name in patch 1, the board compatible name in patch 2, and the actual
.dts file in patch 3.

Please have a look!

Thanks,
Andre

Argh, sorry, managed indeed to mess up this super simple patch!

Will fix it, thanks for having a look and spotting this!

Ah, a good point. The file seems to be sort alphabetically after the
"description" name, though there are some outliers. Will send a patch
to fix them.
But at least this entry is correctly sorted.

[PATCH 3/3] arm64: dts: allwinner: h618: add Transpeed 8K618-T TV box

[Andre Przywara]

This is a Chinese TV box, probably very similar if not identical to
various other cheap TV boxes with the same specs:
      - Allwinner H618 SoC (4 * Arm Cortex-A53 cores, 1MB L2 cache)
      - 2 or 4GiB DDR3L DRAM
      - 32, 64, or 128 GiB eMMC flash
      - AXP313a PMIC
      - 100 Mbit/s Ethernet (using yet unsupported internal PHY)
      - HDMI port
      - 2 * USB 2.0 ports
      - microSD card slot
      - 3.5mm A/V port
      - 7-segment display
      - 5V barrel plug power supply

The PCB provides holes for soldering a UART header or cable, this is
connected to the debug UART0. UART1 is used for the Bluetooth chip,
although this isn't working yet.

It would be great to expand all PMIC regulator names with (known) areas they 
power, so something like "vcc1v8-pll-pc". With that, I think you can remove 
comments.

Not really, and since UART1 is used for Bluetooth, its name should not
matter at all, the BT driver will just use its parent device.
Will remove it.

Alright, will do. I will stick with those users that I am pretty sure
of, either because they are mentioned in the BSP DT, or because they
must be supplied by that rail: there seem to be only one 1.8V source.
