PATCH v5 1/6 arm64: dts: imx8mm: imx8mp: Add LVDS DTOs for Data Modul i.MX8M Mini and Plus eDM SBC

Add DT overlay for the DSI-to-LVDS adapter eDM-MOD-iMX8Mm-LVDS populated with Lontium LT9211 bridge. This adapter can be optionally populated onto the eDM SBC. This adapter can be extended with multiple panels, currently supported are the following:

- AUO G215HVN011
- Innolux G070Y2-L01
- Innolux G101ICE-L01
- Innolux G121XCE-L01
- Innolux G156HCE-L01
- Multi-Inno Technology MI0700A2T-30
- Multi-Inno Technology MI1010Z1T-1CP11

Note that in case of the i.MX8M Plus eDM SBC, the adapter name containing iMX8Mm is not a typo, this is the adapter model string. The adapter was originally developed for the iMX8Mm eDM SBC.

V2: Deduplicate the DTOs further
V3: - Rename buckN to buckN_reg and ldoN to ldoN_reg to be consistent across MX8MM and MX8MP
- Split off anything non-LVDS related
V4: Rebase on next-20260703, drop dependency links which have all landed now
V5: Fix g151hce to g156hce typo

[Severity: Medium]
Do these targets incorrectly include the DSI-to-LVDS adapter overlay (edm-mod-imx8mm) instead of the native LVDS overlay (edm-sbc-imx8mp-lvds) for the SBC?

If so, this might cause the LVDS display pipeline for the rev900 and rev902 i.MX8MP SBCs to be misconfigured. They might expect the lt9211 DSI-to-LVDS adapter instead of the native lcdif2 and lvds_bridge, which could lead to a display probe failure at runtime.

PATCH v5 3/6 arm64: dts: imx8mm: imx8mp: Add HDMI DTOs for Data Modul i.MX8M Mini and Plus eDM SBC

In reply to Marek Vasut

Add DT overlay for the DSI-to-HDMI adapter eDM-MOD-iMX8Mm-HDMI populated with Lontium LT9611 bridge. This adapter can be optionally populated onto the eDM SBC.

PATCH v5 4/6 arm64: dts: imx8mm: imx8mp: Add CM DTOs for Data Modul i.MX8M Mini and Plus eDM SBC

In reply to Marek Vasut

Add DT overlay which adds CM4/CM7 extras so that CM4/CM7 firmware could be used with remoteproc and rpmsg, but without imposing the overhead on every user of the platform. The CM4 variant applies to i.MX8M Mini, while the CM7 variant applies to i.MX8M Plus .

[Severity: High]
Will applying this overlay on the 1 GiB variant of the board cause a crash?

The base board imx8mm-data-modul-edm-sbc.dts supports 1, 2, or 4 GiB variants with physical memory starting at 0x40000000. On a 1 GiB variant, physical memory ends at 0x7FFFFFFF.

Since these memory regions are hardcoded at physical addresses starting at 0xb7000000 and 0xb8000000, they fall outside the available DRAM for 1 GiB boards.

When the remoteproc driver probes and attempts to map and initialize these reserved memory regions, will it access unbacked physical memory and trigger a synchronous external abort?

--- Patch [5]: [PATCH v5 5/6] arm64: dts: imx8mm: imx8mp: Add FIO1 DTOs for Data Modul i.MX8M Mini and Plus eDM SBC --- commit b8816aeaca7378ddfdc8544c5eb07a316a35281c
Author: Marek Vasut <[email protected]>
Subject: arm64: dts: imx8mm: imx8mp: Add FIO1 DTOs for Data Modul i.MX8M Mini and Plus eDM SBC

This patch adds a Device Tree overlay for the eDM-MOD-iMX8Mm-FIO1 feature connector expansion module. It provides additional UARTs, CAN, PWM Beeper, I2C, SPI, and GPIO breakout for the Data Modul i.MX8M Mini and Plus eDM SBC.

[Severity: High]
Will this overlay conflict with the baseboard when applied to the i.MX8MP?

The i.MX8MP baseboard (arch/arm64/boot/dts/freescale/imx8mp-data-modul-edm-sbc.dts) unconditionally defines an LVDS IO expander on the same I2C bus:

	gpiolvds: io-expander@20 {
		compatible = "nxp,pca9554";
		reg = <0x20>;
		...
	};

When this overlay is applied, won't gpio_feature: io-expander@20 merge into
gpiolvds: io-expander@20 and silently overwrite properties like gpio-line-names and interrupt assignments, breaking both configurations?

Additionally, if both the baseboard LVDS PCA9554 and the FIO1 expansion module PCA9554 are physically present, will they cause a hardware collision on the I2C bus at address 0x20 and fail to probe?

Re: [PATCH v5 6/6] arm64: dts: imx8mm: imx8mp: Add FIO1-Audio DTOs for Data Modul i.MX8M Mini and Plus eDM SBC

- [High] Incorrect GPIO interrupt pin mapped for PCA9554 IO Expander on i.MX8MP
- [High] Broken RS485 UART configuration and pinmux RTS conflict on i.MX8MP

Quoted 2 lines

providing additional UARTs, CAN, PWM Beeper, I2C, SPI, GPIO breakout and SGTL5000 codec.

[Severity: Low]
The commit message states that the overlay provides a PWM Beeper, but I do not see a pwm-beeper compatible node or PWM configuration added in these new files.

Is this feature missing from the patch, or should the commit message be updated?

[Severity: High]
This hardcodes the PCA9554 interrupt to &gpio5 4 for both platforms. While this routes correctly on i.MX8MM, doesn't the i.MX8MP SOM route this external connector pin to &gpio1 8?

Since the i.MX8MP dtso doesn't override these properties, will the IO expander listen on the wrong pin and miss interrupts on the i.MX8MP?

[Severity: High]
Applying the RS485 properties to &uart2 works for i.MX8MM, but doesn't i.MX8MP use &uart1 for its RS485 port?

Could this leave &uart1 unconfigured on i.MX8MP while applying invalid properties to &uart2?

[Severity: Medium]
Is it intentional to create a new clock-controller node here?

This unit address overlaps with the existing sai@30050000 node in the base i.MX8MM dtsi. Because the node names differ, dtc will create two duplicate nodes, which can cause an -EBUSY resource conflict during probe.

Should this modify the existing &sai5 node instead?

[Severity: High]
The base i.MX8MP board uses SAI2_RXD0 for the UART1_DCE_RTS pin. Since this audio overlay reclaims SAI2_RXD0 for audio, it drops the RTS pin from this uart1-grp.

Without the RTS pin to control transceiver direction, will the RS485 hardware on i.MX8MP still be functional?

Similar to the i.MX8MM overlay, this creates a new node that overlaps with the existing sai@30c50000 node in the i.MX8MP base tree.

Could this cause duplicate nodes to be generated and lead to resource conflicts?

Thank you for your contribution! Sashiko AI review found 6 potential issue(s) to consider:
- [High] The backlight enable GPIO is hardcoded for the i.MX8MM adapter in the G215HVN011 panel overlay, breaking the backlight on the i.MX8MP native LVDS board.
- [Medium] Incorrect voltage mapping for state 0x3 in the AP63300 regulator configuration, which could lead to severe overvoltage.
- [Medium] The common abstraction file contains an adapter-specific dangling phandle reference to &gpio_display.
- [Low] The patch modifies a core SoC file (imx8mp.dtsi) to add the spba5 label, which is undocumented in the commit message.
- [Low] The MP2328 voltage divider calculation comment is mathematically incorrect for the specified resistors.

Author: Marek Vasut <[email protected]>
arm64: dts: imx8mm: imx8mp: Add LVDS DTOs for Data Modul i.MX8M Mini and Plus eDM SBC

This commit adds device tree overlays for the DSI-to-LVDS adapter eDM-MOD-iMX8Mm-LVDS populated with Lontium LT9211 bridge. It provides support for multiple panels and is intended for use with both the i.MX8M Mini and i.MX8M Plus eDM SBCs.

Does this create a dangling phandle reference when included by the native i.MX8MP adapter overlay? It looks like gpio_display is undefined in that context, which might inject a leaky abstraction into the common file.

[Severity: Medium]
Is the state mapping for 0x3 safe to leave at 3900000? Based on the hardware calculations, it appears this state would actually output around 13.6V. Could this lead to severe overvoltage and hardware damage if a future panel requests 3.9V and the regulator framework switches to this state?

[Severity: High]
Does hardcoding this i.MX8MM-specific GPIO break the backlight when this overlay is used on the native i.MX8MP LVDS board? It seems this bypasses the abstract reg_panel_bl regulator. When the i.MX8MP overlay includes this file, it overrides the power supply but does not override this enable-gpios property, potentially causing it to toggle the wrong pin.

[Severity: Low]
Is the mathematical formula in this comment accurate for this circuit? If the resistors were placed in parallel, the formula
1 / Rx = (1 / R2) + (1 / Rs) with R1=51.1k, R2=5.62k, and Rs=2.21k would yield 16.6V instead of 12V. Does the hardware actually switch between the resistors rather than placing them in parallel?

Could this core SoC DTSI modification be split into a separate patch? Adding the spba5 label here modifies a common architectural file silently during a board-level overlay patch, and it does not appear to be mentioned in the commit message.

Add DT overlay for the DSI-to-LVDS adapter eDM-MOD-iMX8Mm-LVDS populated with Lontium LT9211 bridge. This adapter can be optionally populated onto the eDM SBC. This adapter can be extended with multiple panels, currently supported are the following:
- AUO G215HVN011
- Innolux G070Y2-L01
- Innolux G101ICE-L01
- Innolux G121XCE-L01
- Innolux G156HCE-L01
- Multi-Inno Technology MI0700A2T-30
- Multi-Inno Technology MI1010Z1T-1CP11
Note that in case of the i.MX8M Plus eDM SBC, the adapter name containing iMX8Mm is not a typo, this is the adapter model string. The adapter was originally developed for the iMX8Mm eDM SBC.

compatible should be first property.
reg is second.

there are other places also similar problem. Please double check it.

suggest run https://github.com/lznuaa/dt-format for new dts to avoid this order problem.
