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
V6: Move compatible and reg properties to the beginning of lt9211_codec: bridge@2d { } node
V7: No change
V8: No change
V9: Align resistor values in imx8mp-data-modul-edm-sbc-overlay-edm-sbc-imx8mp-lvds.dtsi

Thank you for your contribution! Sashiko AI review found 3 potential issue(s) to consider:
- [Medium] The G215HVN011 panel overlay hardcodes the backlight enable GPIO, breaking the backlight functionality when used with the native i.MX8MP SBC LVDS interface.
- [Low] Mismatch between the mathematical comment and the actual assigned clock rate for the G156HCE-L01 panel.
- [Low] The built-in i.MX8MP LVDS overlay inherits and incorrectly configures the external adapter's SoC pinctrls for its regulators.

Author: Marek Vasut <marex@nabladev.com>

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.

[Severity: Medium]
Does hardcoding enable-gpios here break the backlight for the native
i.MX8MP SBC LVDS interface?

Since the native LVDS overlay does not override this property, the driver
will toggle the SoC GPIO3_IO00 instead of the correct I2C expander pin,
which might leave the screen black.

Could we abstract this using the reg_panel_bl node instead?

[Severity: Low]
Is there a typo in the comment here? It mentions 993.2 MHz, but the code
configures 993020000 (993.02 MHz).

[Severity: Low]
Since this native LVDS overlay routes the regulator GPIOs to the gpiowifi
I2C expander, does it also need to delete the pinctrl-0 properties inherited
from the base tree and external adapter include?

Without /delete-property/ pinctrl-0; the regulators might still needlessly
request and configure the SoC pins via pinctrl.

[Severity: High]
Will this cause an infinite probe deferral for the backlight?

The supply node reg_panel_bl_supply is being disabled here, but the consumer 
node reg_panel_bl inherits vin-supply = <&reg_panel_bl_supply>; from the 
base DT. 

Because the status property is ignored during phandle parsing, the regulator
framework will find the target node but fail to find a registered device for 
it, returning a permanent -EPROBE_DEFER. 

Should this also remove the reference via /delete-property/ vin-supply; in 
reg_panel_bl?

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.

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 .

Add DT overlay for feature connector expansion module eDM-MOD-iMX8Mm-FIO1
providing additional UARTs, CAN, PWM Beeper, I2C, SPI and GPIO breakout.
This adapter can be optionally populated onto the eDM SBC.

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [High] Device Tree node collision and hardware I2C address conflict for io-expander@20 on i.MX8MP.
- [High] Incorrect UART role configuration for RS485 on i.MX8MP.

--- Patch [6]: [PATCH v9 6/7] arm64: dts: imx8mm: imx8mp: Add FIO1 DTOs for Data Modul i.MX8M Mini and Plus eDM SBC ---
commit a7ddf5cabeef2078bf36b166e42e85f54f0b7289
Author: Marek Vasut <marex@nabladev.com>

arm64: dts: imx8mm: imx8mp: Add FIO1 DTOs for Data Modul i.MX8M Mini and Plus eDM SBC

This commit adds a Device Tree overlay for the eDM-MOD-iMX8Mm-FIO1 feature
connector expansion module. The adapter provides additional interfaces like
UARTs, CAN, PWM Beeper, I2C, SPI, and GPIO, and can be optionally populated
onto the eDM SBC.

[Severity: High]
Does this cause a device tree node collision on the i.MX8MP?

When this shared FIO1 overlay is applied to the i.MX8MP baseboard, it
appears this will overwrite the statically defined gpiolvds: io-expander@20
node on the &i2c2 bus (aliased as &i2c_feature).

This would replace the LVDS GPIO line names and interrupt configurations with
the FIO1 configurations, potentially breaking the LVDS expander controls.

Also, does physically connecting the FIO1 expansion board to the i.MX8MP SBC
cause a hardware I2C address collision at 0x20 on i2c2?

> +};

[Severity: High]
Are these UART role configurations correct for both i.MX8MM and i.MX8MP?

The shared overlay hardcodes &uart2 as RS485 and &uart1 as standard UART,
which is correct for i.MX8MM. However, the i.MX8MP baseboard appears to
rely on &uart1 for RS485 and &uart2 for standard UART.

Applying this shared overlay to i.MX8MP might improperly enable RS485 on
&uart2, causing it to try to toggle RTS as RS485 transmit enable (breaking
hardware flow control), while leaving the actual RS485 port (&uart1)
misconfigured.

commit c5a51996123e2650a624a6ad09a9ec065dfa47f6
Author: Marek Vasut <marex@nabladev.com>

arm64: dts: imx8mm: imx8mp: Add FIO1-Audio DTOs for Data Modul i.MX8M Mini and Plus eDM SBC

This commit adds Device Tree Overlays for the eDM-MOD-iMX8Mm-FIO1-Audio
feature connector expansion module. The module provides an SGTL5000 codec,
CAN, PWM, UARTs, and other IO for the Data Modul i.MX8M Mini and Plus
eDM SBCs.

[Severity: Low]
Will this trigger unique_unit_address warnings during DT validation?

The base imx8mm.dtsi already defines an sai@30050000 node inside spba2.
Adding a sibling clock-controller@30050000 node creates two nodes with the
same unit address. Even though the base sai node is disabled, this violates
the DT specification that sibling nodes must have unique addresses.

Would it be better to override the existing &sai5 node directly, or
explicitly delete it first with /delete-node/ &sai5?

[Severity: Low]
Does this also conflict with the existing sai@30c50000 node in spba5
defined in the base imx8mp.dtsi?

Like the i.MX8MM overlay, this adds a clock-controller@30c50000 sibling
node that shares a unit address with the existing sai node.

Should this overlay override &sai5 directly or delete the existing node
first to avoid DT validation warnings?
