[PATCH v2 0/2] Add devicetree for NXP i.MX93 FRDM board

[PATCH v2 0/2] Add devicetree for NXP i.MX93 FRDM board

[Fabian Pflug]

I could not test all features of the board, therefore a lot of stuff is
omitted from the devicetree. but this is enough to have the board boot
via eMMC or SD-Card, debug via debug USB connector and have a network
connection.

The FRDM i.MX 93 development board is a low-cost and compact development
board featuring the i.MX93 applications processor.

It features:
- Dual Cortex-A55
- 2 GB LPDDR4X / LPDDR4
- 32 GB eMMC5.1
- MicroSD slot
- GbE RJ45 x 2
- USB2.0 1x Type C, 1x Type A

This file is based upon the one provided by nxp in their own kernel and
yocto meta layer for the device, but adapted for mainline.

Changes in v2:
- 1/2: remove CAN node, as it has not been tested.
- 1/2: ran dt-format (Thanks Frank Li)
	But also reordered some nodes afterwards again to have
	regulator-min before regulator-max, have the pinmux at the end
	of the file, and have the regulator-name as the first node
	inside the regulators.
	Re-added comments, that were deleted.
- 1/2: changes subjet to ar64:dts (Thanks Fabio Estevan)
- 1/2: removed reg_vdd_12v (Tanks Fabio Estevan)
- 1/2: added aliases for rtc, emmc, serial (Thanks Fabio Estevan)
- reordered the series to have documentation before dts. (Thanks
  Krzystof Kozlowski)
- Link to v1: https://lore.kernel.org/r/20250523-fpg-nxp-imx93-frdm-v1-0-546b2d342855@pengutronix.de

Hello Fabian,

Can you also add the original S-o-b to give credit to NXP
developers who started this?

Testing this on the actual hardware, I have a deferred probe for the cm33
remoteproc, and that's because mu1 is disabled on the parent dtsi.

I am seeing this error on startup:

[   19.076704] platform remoteproc-cm33: deferred probe pending: imx-rproc: failed to request tx mailbox channel

and then, every time a new device is registered (e.g., when connecting a
USB device):

[   68.473051] remoteproc remoteproc0: releasing imx-rproc


Please consider adding:

&mu1 {
	status = "okay";
};
