[PATCH 1/2] bindings: arm: fsl: Add PHYTEC phyBOARD-Nash-i.MX93 board

[Primoz Fiser]

Add devicetree bindings for PHYTEC phyBOARD-Nash-i.MX93 board based on
the existing PHYTEC phyCORE-i.MX93 SoM (System-on-Module).

Adjust the compatibles for the existing phyBOARD-Segin-i.MX93 board, to
be able to add additional board based on the phyCORE-i.MX93 SoM.

[PATCH 2/2] arm64: dts: freescale: Add PHYTEC phyBOARD-Nash-i.MX93 support

[Primoz Fiser]

Add initial support for PHYTEC phyBOARD-Nash-i.MX93 board [1] based on
the PHYTEC phyCORE-i.MX93 SoM (System-on-Module) [2].

Supported board features:
 * ADC
 * CAN
 * Ethernet 2x
 * EEPROM
 * eMMC
 * Heartbeat LED
 * RTC
 * RS-232/RS-485
 * SD-card
 * TPM 2.0
 * USB

For more details see the product pages for the development kit and the
SoM:

Hi Primoz,

a few of the node references you are adding are out of alphabetical order.

eMMC and Hearbeat LED are not board features but SoM features.

Only &mdio node is out of alphabetical order.

But this is done by choice to keep it together with &eqos node since
both nodes are related to the 2nd Ethernet interface (&ethphy2) and thus
kept logically with each other.

We did the same for phyBOARD-Segin-i.MX93.

That's true.

I will remove those from the list in v2 and only list carrier-board
features.
