[PATCH v2 00/15] var-som-6ul: improve support for variants

[Hugo Villeneuve <hugo@hugovil.com>]

From: Hugo Villeneuve <hvilleneuve@dimonoff.com>

Hello,
this patch series improves support for Variscite VAR-SOM-6UL based boards.

The first two patches fix DT/dmesg warnings.

The next patches fix the incorrect use of VAR-SOM-MX6UL to refer to the
VAR-SOM-6UL.

The next patches add support for the imx6ull CPU variant of the VAR-SOM-6UL.

Then improves/fixes the following features/options that are currently not
working on the concerto EVK board:
  - ethernet ports ENET1
  - LVDS display panel
  - Wifi/Bt

Note that the previous configuration of the optional Wifi/Bluetooth module
was copied from the original Variscite kernel tree, and required custom
shell scripts to properly configure the Wifi/Bluetooth module.

Also factor out optional features into separate DTSI include files, so it will
be easier to support them for other boards, and to make sure they are not
unconditionnally enabled.

I have tested these changes on a Variscite concerto EVK board using a
VAR-SOM-6UL with the following options:
  - EC (ethernet phy on SOM)
  - LD (LVDS encoder assembled on SOM)
  - WBD (Wi-Fi 802.11 ac/a/b/g/n and Bluetooth 5.2/BLE on SOM)
Result of tests:
  - Both ethernet ports Ok
  - LVDS display panel Ok
  - Wifi/Bt Ok

Also tested on a custom board with a VAR-SOM-6UL SOM (will be submitted in
a future series).

Thank you.
