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

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.

Add DT overlay for feature connector expansion module eDM-MOD-iMX8Mm-FIO1-Audio
providing additional UARTs, CAN, PWM Beeper, I2C, SPI, GPIO breakout and
SGTL5000 codec. This adapter can be optionally populated onto the eDM SBC.

V2: Deduplicate the DTOs further
V3: New patch split from the original megapatch
V4: Rebase on next-20260703, drop dependency links which have all landed now
V5: No change
V6: Move compatible and reg properties to the beginning of sgtl5000_fio: codec@a {} node
V7: No change

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Medium] Incorrect backlight enable GPIO and pinctrl applied for the g215hvn011 panel on the native i.MX8MP LVDS interface.
- [Medium] The `assigned-clock-rates` property in `&media_blk_ctrl` lacks the required `assigned-clocks` property, causing the LVDS panel clock configuration to be silently ignored.

--- Patch [2]: [PATCH v7 2/7] arm64: dts: imx8mm: imx8mp: Add LVDS DTOs for Data Modul i.MX8M Mini and Plus eDM SBC ---
commit 57ce2b382e55c1c98951209e8e0a8f4ea3f2c65c
Author: Marek Vasut <marex@nabladev.com>
arm64: dts: imx8mm: imx8mp: Add LVDS DTOs for Data Modul i.MX8M Mini and Plus eDM SBC
This patch adds DT overlays for the DSI-to-LVDS adapter populated with a
Lontium LT9211 bridge on Data Modul i.MX8M Mini and Plus eDM SBCs. It
supports multiple panels for both the bridge and native i.MX8MP LVDS
interfaces.

[Severity: Medium]
Will this result in the wrong GPIO being toggled for the native i.MX8MP LVDS
interface?
The shared imx8mm-data-modul-edm-sbc-overlay-lvds-g215hvn011.dtsi file hardcodes
enable-gpios to &gpio3 0 and defines a pinctrl. However, the native i.MX8MP
LVDS interface uses the IO expander's &gpiowifi 0 (via reg_panel_bl in
edm-sbc-imx8mp-lvds.dtsi).
Since this overlay only overrides power-supply and does not remove the
inapplicable pinctrl or override enable-gpios, won't the backlight driver
toggle the incorrect baseboard adapter GPIO pin instead of the intended one?

[Severity: Medium]
Will this clock configuration be silently ignored by the clock framework?
This overlay (and several others for the native LVDS interface) defines
assigned-clock-rates without providing or inheriting an accompanying
assigned-clocks array.
The base board file imx8mp-data-modul-edm-sbc.dts does not include
imx8mp-nominal.dtsi, where the assigned-clocks array is typically defined.
When assigned-clocks is missing, of_parse_phandle_with_args() returns -ENOENT,
and __set_clk_rates() silently skips setting the rates. Should assigned-clocks
be explicitly defined here so the panel clock frequency is correctly set?

Thank you for your contribution! Sashiko AI review found 6 potential issue(s) to consider:
- [High] Hardware Interrupt Routing Mismatch causes PCA9554 GPIO expander to conflict with CAN1 on i.MX8MP.
- [High] The `fsl,sai-asynchronous` property breaks audio capture (and playback) on both i.MX8MM and i.MX8MP due to missing clock routing.
- [High] The i.MX8MP overlay fails to configure the clock parent and rate for `sai5clk`, resulting in an invalid MCLK for the SGTL5000 codec.
- [High] Duplicate `unique_unit_address` causes devres memory region conflict between `sai5clk` and `sai5` drivers.
- [High] The shared `.dtsi` unconditionally disables `uart4`, breaking onboard Bluetooth on the i.MX8MP SBC.
- [Low] Commit message inaccurately claims the overlay provides a "PWM Beeper" and "additional UARTs".

--- Patch [7]: [PATCH v7 7/7] arm64: dts: imx8mm: imx8mp: Add FIO1-Audio DTOs for Data Modul i.MX8M Mini and Plus eDM SBC ---
commit 43246870359af0cd7d3d40f8db5eaaff8fad43a1
Author: Marek Vasut <marex@nabladev.com>
arm64: dts: imx8mm: imx8mp: Add FIO1-Audio DTOs for Data Modul i.MX8M Mini and Plus eDM SBC
Add DT overlay for feature connector expansion module eDM-MOD-iMX8Mm-FIO1-Audio
providing additional UARTs, CAN, PWM Beeper, I2C, SPI, GPIO breakout and
SGTL5000 codec. This adapter can be optionally populated onto the eDM SBC.
> Add DT overlay for feature connector expansion module eDM-MOD-iMX8Mm-FIO1-Audio

[Severity: Low]
Is this description accurate? The commit message mentions a PWM Beeper and
additional UARTs, but the code below disables uart4 and repurposes the
SPDIF_TX pin used for the beeper as a GPIO instead.

[Severity: High]
Does this interrupt routing conflict on the i.MX8MP baseboard?
The shared overlay hardcodes the PCA9554 interrupt to GPIO5_IO04, which is
correct for i.MX8MM. However, on i.MX8MP, this pad (SPDIF_RX) is physically
routed and configured for CAN1_RX.
Could this cause the GPIO expander interrupts to fail and CAN traffic to
trigger spurious GPIO interrupts when loaded on the i.MX8MP? Would it be
better to override this interrupt in the i.MX8MP overlay?

[Severity: High]
Could this fsl,sai-asynchronous property break audio capture?
It forces the SAI block to use independent clocks for TX and RX. However, the
pinmux routing on i.MX8MM only provides RX_BCLK and TX_SYNC, meaning RX
lacks a SYNC clock. On i.MX8MP, only TX clocks are routed, leaving RX without
both BCLK and SYNC clocks.

[Severity: High]
Will disabling uart4 here break the onboard Bluetooth on the i.MX8MP SBC?
This file is shared between the i.MX8MM and i.MX8MP overlays, but on the
i.MX8MP SBC, uart4 is actively used for the infineon,cyw55572-bt module.

[Severity: High]
Can this cause a devres memory region conflict during driver probe?
This overlay adds a new clock-controller node with the exact same unit address
and register range as the existing sai@30050000 audio node.
Since both drivers will use devm_platform_ioremap_resource() to request the
region exclusively, whichever probes second might receive -EBUSY and fail.

[Severity: High]
Similar to the i.MX8MM overlay, can this cause a memory region conflict with
the existing sai@30c50000 audio node?

[Severity: High]
Does this node also need assigned-clocks and assigned-clock-rates configured?
Unlike the i.MX8MM variant, this node leaves the MCLK unconfigured. The
SGTL5000 driver and simple-audio-card do not dynamically set this clock rate
via clk_set_rate() unless mclk-fs is defined.
Could this leave the clock at 0 Hz and prevent the codec from functioning on
the i.MX8MP?
