The A20-Linova1-7 HMI, also called Q027_2_F which is printed on production
label, is an industrial Human Machine Interface.
It features:
- 512MB DDR RAM
- 1 Sd-card >= 4GB
- 1 Usb otg(programmable via software) with A-Usb Connector
- 1 Usb host
- 1 Buzzer
- 1 Input for LiPo
- 1 Relay to signal absence of power supply
- 1 External Rtc with 56 bytes of ram + CR2032 battery
- 1 7" 24-bits Tft 800x480 with PCap on
- 1 Mono audio 1-watt amplifier
- 1 RS485 port
- 1 Power On Line through +12Vdc reaching 57.600baud,
from where it can be supplied and placed in a network of 50 units
- exposed jtag pins
HMI is supplied from +12Vdc.
Ethernet is absent, so for debugging, need to enable rndis on Usb otg
port through an A-A usb cable.
It comes in different flavours for connector types and can be found with
umounted features as requested by customers.
So this is essentially the same board than in patch 6, but with a
different screen?
You should have a single DT then, and handle the two different panels
using DT overlays.
Ok for having different DT overlays.
But do I have to submit them as patches? Or keep them in my company's repo?
I ask you this because this involves sending also patches for displays
and other little modifications to mainline ex:
- rgb888 pins
- 2 simple-panels
- 1 uart iomux pins
etc.
If I don't submit those overlays, the other patches wouldn't make sense
alone as I've seen, just like rgb888 pins.

These bindings are unnecessary, but the panel-simple bindings should
be sent to the DT maintainers as well.
Ok, removed them and already sent the ones for display.

You should have a space after dtb, and it should be ordered
alphabetically.
Done.

Ideally you should be defining the regulators here too.

You're saying that this is a USB-A connector? Then it's not OTG since
it doesn't have an ID pin, this is an host.
Right, with a special overlay I will activate Usb Device for RNDIS,
so modified as host

The nodes should be ordered by alphabetical order.
Done.
One last question:
now I have some patch already reviewed-by.
Do I have to re-submit entire patchset?
Thank you very much.
