Date: Wed, 27 Mar 2024 12:07:31 +0530	[thread overview]
Message-ID: <20240327063734.3236117-1-sumit.garg@linaro.org> (raw)

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.
