[PATCH v4 2/2] arm64: dts: freescale: add i.MX95 19x19 FRDM PRO board dts

[Joseph Guo]

NXP i.MX95 19x19 FRDM PRO is cost-effective with extensive
expansion capabilities based on the i.MX95 19x19 SoC.
It is designed for AI and robotic situation.
Difference with i.MX95 15x15 FRDM:
- Use i.MX95 19x19 package
- Support 2 KEY-M M.2 PCIE
- 10G ETH interface
- Secure Element interface

Add device tree for this board. Including:
- LPUART1 and LPUART5
- NETC
- USB
- 2 M-Key M.2 PCIe
- uSDHC1, uSDHC2 and uSDHC3
- FlexCAN1 and FlexCAN3 (CAN1 is reserved by M7)
- LPI2C3, LPI2C4 and their child nodes
- Watchdog3
- SAI, MQS, MICFIL

Re: [PATCH v4 2/2] arm64: dts: freescale: add i.MX95 19x19 FRDM PRO board dts

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 5 potential issue(s) to consider:
- [High] Architectural flaw preventing the M7 core from using the CAN1 transceiver.
- [High] Incorrect drive strength in `pinctrl_usdhc2_200mhz` causing potential SD card instability.
- [Medium] Mismatch between commit message claiming 10G ETH support and device tree implementation.
- [Medium] Dead pinctrl configuration in the reserved `flexcan1` node.
- [Low] Unused `reg_3p3v` regulator node.

commit 65457c99452cde3ade57a7afda12053dd0e2d5ee
Author: Joseph Guo <qijian.guo@nxp.com>

arm64: dts: freescale: add i.MX95 19x19 FRDM PRO board dts
    
This commit adds the device tree for the NXP i.MX95 19x19 FRDM PRO board,
which is based on the i.MX95 19x19 SoC. It configures various peripherals
including USB, PCIe, ethernet, CAN, and regulators.

> - 10G ETH interface

The commit message claims support for a 10G ETH interface, but the device tree
only configures enetc_port0 and enetc_port1 as 1 Gbps rgmii-id interfaces and
entirely omits the i.MX95 10G Ethernet MAC. Is this omission intentional?

Is this regulator used anywhere? It doesn't have the regulator-always-on
property and isn't referenced by any device node as a supply.

Will the M7 core be able to use the CAN1 transceiver with this setup?

Since flexcan1 is marked as reserved, the Linux CAN driver won't probe it.
As a result, Linux will never power on flexcan1_phy or drive the standby GPIO
low. The Linux driver core will also ignore the pinctrl-0 configuration.

If the M7 core depends on Linux to set up the pin multiplexing and enable the
PHY, does this need a gpio-hog on the expander and the pinctrl moved to an
active pinctrl_hog group instead?

Are these pad settings correct for 200MHz operation?

These use the exact same pad settings (0x138e and 0x158e) as the 100MHz group,
whereas usdhc1 and usdhc3 correctly configure higher drive strength (0x13fe and
0x15fe) for 200MHz. Can this lower drive strength cause signal integrity
issues or CRC errors with the SD card at 200MHz?
