[PATCH 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.

What do you think about adding aliases for the usdhc and rtc nodes?

Please organize the patch documenting compatible (DT bindings) before
their user.

This is an automated instruction, just in case, because many review tags
are being ignored. If you know the process, you can skip it (please do
not feel offended by me posting it here - no bad intentions intended).
If you do not know the process, here is a short explanation:

Please add Acked-by/Reviewed-by/Tested-by tags when posting new versions
of patchset, under or above your Signed-off-by tag, unless patch changed
significantly (e.g. new properties added to the DT bindings). Tag is
"received", when provided in a message replied to you on the mailing
list. Tools like b4 can help here. However, there's no need to repost
patches *only* to add the tags. The upstream maintainer will do that for
tags received on the version they apply.

Since d80bfde3c57a ("can: flexcan: add transceiver capabilities"), which
got mainline with v6.15-rc1 there is proper PHY support in the flexcan
driver. So from my point of view, there's no need to stick to regulator
hack.

See 87d60c4663b6 ("arm64: dts: ti: k3-j721e-common-proc-board: Add
support for mcu and main mcan nodes") for an example.
