[PATCH 0/8] arm64: dts: freescale: Add Verdin iMX8M Mini overlays

[Ernest Van Hoecke]

This series adds device tree overlays for the Toradex Verdin iMX8M Mini
SoM. The overlays cover audio configuration, display adapters, DSI
displays, OV5640 CSI camera modules, and Cortex-M4F integration.

The series adds support for:
- NAU8822 Bridge Tied Load configuration on the Verdin Development Board
- DSI-to-HDMI adapter based on the Lontium LT8912B bridge
- DSI-to-LVDS adapter based on the TI SN65DSI84 bridge, combined with the
  Toradex Capacitive Touch Display 10.1" LVDS
- Toradex Capacitive Touch Display 7" and 10.1" DSI variants
- Toradex OV5640 CSI camera variants with 27 MHz and 24 MHz oscillators
- Cortex-M4F remoteproc support

Cortex-M4F support is split between the SoM description and an optional
UART_4 overlay. The SoM dtsi describes the remote processor and RPMsg
reserved-memory regions, while the overlay reserves Verdin UART_4 for
Cortex-M4F firmware use.

The Makefile entries build the standalone overlays as DTBOs, add
ready-to-use composed DTBs for selected carrier board and accessory
combinations, and add representative composed DTBs for build-time
coverage.

[PATCH 1/8] arm64: dts: freescale: imx8mm-verdin: Add NAU8822 Bridge Tied Load

[Ernest Van Hoecke]

From: Ernest Van Hoecke <ernest.vanhoecke@toradex.com>

Add a device tree overlay for configuring the NAU8822 loudspeaker
outputs as a Bridge Tied Load (BTL) output on the Verdin Development
Board.

The overlay adds the codec property for the BTL-capable output
configuration, where the two loudspeaker outputs are combined for higher
output power.

[PATCH 2/8] arm64: dts: freescale: imx8mm-verdin: Add DSI to HDMI adapter overlay

[Ernest Van Hoecke]

From: Ernest Van Hoecke <ernest.vanhoecke@toradex.com>

Add a device tree overlay for the Toradex DSI to HDMI Adapter, an
accessory that connects to the Verdin DSI_1 interface and provides a
full-size HDMI Type-A output. The adapter is based on the Lontium
LT8912B DSI-to-HDMI bridge.

The overlay is also combined with the Verdin iMX8M Mini carrier board
device trees to provide ready-to-use DTBs for the Dahlia, Yavia and
Development Board carriers, in both WiFi and non-WiFi SoM variants.

[PATCH 3/8] arm64: dts: freescale: imx8mm-verdin: Add Toradex DSI to LVDS adapter with 10.1" display

[Ernest Van Hoecke]

From: Ernest Van Hoecke <ernest.vanhoecke@toradex.com>

Add a device tree overlay for the Toradex DSI to LVDS Adapter with the
Toradex Capacitive Touch Display 10.1" LVDS. The adapter connects to the
Verdin DSI_1 interface. It is based on the Texas Instruments SN65DSI84
DSI-to-LVDS bridge and drives a LogicTechno LT170410-2WHC 10.1" WXGA IPS
LCD panel. Touch input is provided by an Atmel maXTouch capacitive touch
controller.

[PATCH 4/8] arm64: dts: freescale: imx8mm-verdin: Add Toradex Capacitive Touch Display 10.1" DSI

[Ernest Van Hoecke]

From: Ernest Van Hoecke <ernest.vanhoecke@toradex.com>

Add a device tree overlay for the Toradex Capacitive Touch Display
10.1" on the Verdin DSI_1 interface. The display features an internal
Texas Instruments SN65DSI83 DSI-to-LVDS bridge driving a Riverdi
RVT101HVLNWC00 10.1" WXGA IPS TFT LCD panel. The touch input is
provided by an Ilitek ILI2132 capacitive touch controller.

The overlay is also combined with the Verdin iMX8M Mini Dahlia carrier
board device trees to provide ready-to-use DTBs in both WiFi and
non-WiFi SoM variants.

[PATCH 6/8] arm64: dts: freescale: imx8mm-verdin: Add Toradex OV5640 CSI Cameras

[Ernest Van Hoecke]

From: Ernest Van Hoecke <ernest.vanhoecke@toradex.com>

Add device tree overlays for the Toradex OV5640 CSI Camera on Verdin CSI_1.

The default overlay describes the current CSI Camera Set 5MP OV5640 with a
27 MHz on-board oscillator. Add a separate 24 MHz overlay for the legacy
camera module.

Need not add dtbo here,

+dtb-$(CONFIG_ARCH_MXC) += imx8mm-verdin-wifi-dev-ov5640-24mhz.dtb can
auto dtbo build dtbo.

check other dtbo.

Hi Frank,

Thanks for the review.

Our desire is that these dtbo's are standalone targets that are shipped
for runtime overlay application. Users might, on dev boards especially,
want to enable or disable any combination of these overlays, and change
the combination between boots.

The combined dtb targets validate the overlay and in some listed cases,
provide a ready-to-use combo. They are not intended to cover all
possible use-cases.

My understanding is that indeed a dtb-y targeting a combined DTB will
build the prerequisite dtbo, but it would not be an install target.

Kind regards,
Ernest

I think with the Toradex ecosystem there would be some value in
supporting or helping with the ongoing dt-connectors or dt-addons topics
so that we can abstract the hardware which is being 'added'.

I think it's important that we tackle the problem of combinatorial
explosions of overlays when we can add a component to multiple
platforms.

For example, your OV5640 camera could be added to many different boards
- and each board could have many different cameras - in different ports.

We should not be copy/pasting overlays for each combination, or we'll
have 'thousands' of identical overlays.

I see your point, and I agree that it would be valuable to move this
topic forward. I will raise it internally at Toradex and see how we can
contribute.

At the same time, quoting Marex (https://lore.kernel.org/all/dec2a7f6-80fd-4692-8936-969f8837a555@nabladev.com/):

Indeed, it's been around for a long time - and yet the problem persists,
and that's why it worries me here. It won't be fixed until someone works
on it or supports the development.

Marex is an independent community developer - without someone buying products
to support his development. It wouldn't be fair to push back on him
personnally. He has no mechanism to support the development required.

I do quick check for ov5640, we can use partial connectors, which already
in kernel tree.

use duplicate label like

in mainboard
csi_io_i2c: &i2c3 {
	...
}

csi_io_regualotor_3v3: ....


csi_io: connector_csi {
	compatible = "...";
	gpio-map = <0 0 &gpio1 3 3>;
	...
	irq-map =<0 &gpio1 4 1>;
	...
}

in 5640 overlay

&csi_io_i2c {
	camera@xx {

		reset-gpios = <&csi_io 0 ACTIVE_HIGHT>;
	}
}

https://lore.kernel.org/imx/AM9PR04MB8353AC7DF91C5F73C34019E0E3F72@AM9PR04MB8353.eurprd04.prod.outlook.com/

Only clock part have dependence. other parts. I am working mipi dsi for
display, almost work except panel show have some problem, which is not
related with connector.

This is very interesting and I agree with both you and Kieran that it
would be great to abstract these connections away and kill the need for
so many variations.

Certainly I will read up on this and spread it internally as well.

That said, since there are still unresolved dependencies, I am not
convinced that we should already head this way with this series. It
supports hardware that exists today in the currently standard and clean
way.

Can we consider moving to this once these patches are merged and we see
benefit?

Kind regards,
Ernest

[PATCH 8/8] arm64: dts: freescale: imx8mm-verdin: Add Cortex-M4F UART_4 overlay

[Ernest Van Hoecke]

From: Ernest Van Hoecke <ernest.vanhoecke@toradex.com>

Verdin UART_4 can be assigned to Cortex-M4F firmware. Add an overlay
that marks the UART as reserved so Linux does not claim the port.

The overlay is also combined with the Verdin iMX8M Mini Development
Board device tree to provide a ready-to-use DTB for the WiFi SoM
variant.
