[PATCH v4 0/3] Add Variscite i.MX6UL SoM and Concerto board support

[Antonin Godard]

Add support for the i.MX6UL Variscite SoM (VAR-SOM-6UL) and the
Variscite Concerto Carrier Board.

I tested this with a VAR-SOM-6UL_G2_700C_512R_8N_IT_REV1.3A (one variant
of this SoM), meaning I couldn't test all of the possible options of the
SoM - so this device tree includes partial support for it.

These are based on the 5.15 Variscite kernel fork but adapted for
mainline.
