  To: distrokit; +Cc: Fabian Pflug

A new board, with an IMX93 processor.

- Barebox patch has been send upstream and accecpted into next
- magic number ist chosen at random
- has been tested on real hardware

Signed-off-by: Fabian Pflug <f.pflug@pengutronix.de>

There is still a small issue with USB-WLAN module not working.

v1 -> v2:
  - reworded uploading in docs (Ahmad)
  - fix spelling error in commit message (Ahmad)
  - added barebox-env/bootloader GPT partition (Ahmad)

+Subject: [PATCH] ARM: dts: tqma93xx add dummy supply to regulator
+
+The regulator for the usdhc2 references the BUCK4 as its input.
+The BUCK4 is part of the pca9451, which in turn is not a regulator
+in barebox, so there is a problem during initialisation:
+
+WARNING: imx-esdhc 42860000.mmc@42860000.of: Failed to get 'vmmc' regulator (ignored)
+
+Since the dependency could not be resolved, the reg_usdhc2_vmmc
+regulator is not correctly initialized, leaving the gpio in a floating
+state, which results in the GPIO being low, which in turn disables
+the SD-Card.
