[PATCH 0/4] arm64: dts: freescale: Add Verdin iMX8M Plus overlays

[Ernest Van Hoecke]

This series adds device tree overlays for the Toradex Verdin iMX8M Plus
SoM. The overlays cover audio configuration, a display adapter, and DSI
displays.

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
- Toradex Capacitive Touch Display 7" and 10.1" DSI variants

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

[PATCH 1/4] arm64: dts: freescale: imx8mp-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 2/4] arm64: dts: freescale: imx8mp-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 Plus 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 3/4] arm64: dts: freescale: imx8mp-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 Plus Dahlia carrier
board device trees to provide ready-to-use DTBs in both WiFi and
non-WiFi SoM variants.

[PATCH 4/4] arm64: dts: freescale: imx8mp-verdin: Add Toradex Capacitive Touch Display 7" DSI

[Ernest Van Hoecke]

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

Add a device tree overlay for the Toradex Capacitive Touch Display 7"
on the Verdin DSI_1 interface. The display features an internal Texas
Instruments SN65DSI83 DSI-to-LVDS bridge driving a Riverdi
RVT70HSLNWCA0 7" WSVGA IPS TFT LCD panel. The touch input is provided
by an Ilitek ILI2132 capacitive touch controller.

Hi Frank,

Is there anything blocking this series from being picked up?

Thank you and kind regards,

I defer all display overlay patches because clock nexus node support
already added.

I hope your ov5460 can move forward. I prefer use this method.
