[PATCH v4 0/2] Introduce basic support for MR-NAVQ95

[Laurentiu Mihalcea <laurentiumihalcea111@gmail.com>]

From: Laurentiu Mihalcea <laurentiu.mihalcea@nxp.com>

Hi folks,

So, as the title says, this series attempts to introduce basic support for
NXP's MR-NAVQ95 board. The "basic support" refers to introducing a new DTS
and enabling a couple of peripherals so that the board'll be able to boot
from eMMC/SD/NFS.

So, compared to MX95-19x19-EVK, this board has a smaller form factor
(comparable to the MX95-based FRDM boards) and is designed for
robotics-related applications (e.g. drones, rovers, humanoids, etc...).
The board is currently at revision B and is only available internally.
The board should be officially announced around October/November 2026.

Given that the board and its support are fairly new and still under
development, I would expect some (hopefully) small changes to the DTS.
Hopefully, this'll be acceptable.

The schematics, a brief overview and some pictures of the board are
publicly available at [1].

Changes in v4:

* added missing "memory" node.

* link to v3: https://lore.kernel.org/imx/20260901131918.1189-1-laurentiumihalcea111@gmail.com

Changes in v3:

* use "gpios" instead of the deprecated "gpio" for the "regulator-usdhc2"
node.

* fix issues raised by running "dt-check-style --mode strict". Note that
"dt-check-style" still reports the following issues:

[property-order] property 'compatible' out of canonical order [...]
[line-length] line exceeds 80 columns [...]

these'll be fixed by Krzysztof Kozlowski's on-going patches: [3]. Manually
applied his patches and dt-check-style seems happy with the DTS.

Changes in v2:

* remove the "pinctrl_usdhc2_100mhz", "pinctrl_usdhc2_200mhz", and
"pinctrl_usdhc1_100mhz" DT nodes as they have the same configuration
as "pinctrl_usdhc2" and "pinctrl_usdhc1", respectively.

* add "bootph-pre-ram" property to all nodes that were included in Elena's
u-boot patches. See [2]. Note that "imx95-u-boot.dtsi" is still required
for the binman node and for the rest of the nodes tagged with
"bootph-pre-ram".
