[PATCH 6/6] imx: imx6ul: kontron-sl-mx6ul: Sync devicetrees

Frieder Schrempf frieder at fris.de
Tue Aug 23 16:29:15 CEST 2022 

From: Frieder Schrempf <frieder.schrempf at kontron.de>

Sync the devicetrees with Linux and adjust the board names.

Signed-off-by: Frieder Schrempf <frieder.schrempf at kontron.de>

Note:

* The devicetree changes this is based on are still pending in Linux
  (see https://patchwork.kernel.org/project/linux-arm-kernel/cover/20220815082814.27651-1-frieder@fris.de/).
