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 v5:
- Addressed another nitpick from Stephen.
- Collected Stephen's review tag.
- 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 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.

Please do not resend regular patches during merge window. Nothing can
happen now, no one will pick it up, so probably you will need another
resend later. This just creates really unnecessary traffic on the
mailing lists.
Best regards,

You are right. I suppose the reason for my hurry is not to miss the
next v6.11 release cycle as the v6.10 release cycle has already passed
for this patchset to be picked up. It has nearly been 6 weeks since
the original v5 patch-set [1] was posted and not being picked up even
after it has gone through extensive review. I am really failing to
understand the missing pieces or any unaddressed feedback to get this
accepted.
However, as you have suggested I will resend again after the merge
window closes.
