[PATCH v4 0/3] arm64: dts: qcom: apq8016: Add Schneider HMIBSC board DTS

[Sumit Garg]

Add Schneider Electric HMIBSC board DTS. The HMIBSC board is an IIoT Edge
Box Core board based on the Qualcomm APQ8016E SoC. For more information
refer to the product page [1].

One of the major difference from db410c is serial port where HMIBSC board
uses UART1 as the debug console with a default RS232 mode (UART1 mode mux
configured via gpio99 and gpio100).

Support for Schneider Electric HMIBSC. Features:
- Qualcomm Snapdragon 410C SoC - APQ8016 (4xCortex A53, Adreno 306)
- 1GiB RAM
- 8GiB eMMC, SD slot
- WiFi and Bluetooth
- 2x Host, 1x Device USB port
- HDMI
- Discrete TPM2 chip over SPI
- USB ethernet adaptors (soldered)

This series is a v2 since v1 of this DTS file has been reviewed on the
U-Boot mailing list [2].

Changes in v4:
- Dropped IRQ_TYPE_EDGE_FALLING for pm8916_resin given the expectations
  of Linux kernel driver. Instead depend on systemd workaround suggested
  by Caleb to get expected HMIBSC reset behaviour.
- Incorporated further DT coding style comments from Stephen.
- Warnings reported by Rob's DT check bot aren't related to HMIBSC
  board DTS but rather they are due to msm8916.dtsi or extcon-usb-gpio.txt
  still not converted to YAML format.

Changes in v3:
- Picked up tags.
- Fixed further DT schema warnings.
- Configure resin/power button interrupt as falling edge.
- Incorporate DTS coding style comments from Krzysztof and Konrad.

Changes in v2:
- Fix DT schema warnings.
- Incorporate suggestions from Stephan.
- Document UART1 mode GPIOs based mux.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade

This looks good to me now. Thanks for making all the changes!

Reviewed-by: Stephan Gerhold <stephan@gerhold.net>

Please drop the tag again in case you send another version with any
larger changes. I'm happy to look at the patch again then. Not sure if
Caleb's R-b is still valid now after all the changes you made.

I found one more nitpick below, but it also exists in apq8016-sbc.dts.
Feel free to leave it as-is, I can fix it up for both sometime later.

Thanks,
Stephan

Nitpick: &usb_hub_reset_pm has input-disable (and the two others below),
but this one doesn't.
