[PATCH v2 0/2] watchdog: qcom: introduce qcom-wdt driver

[Paul Sajna]

Sidenote: I needed to update the devicetree for judyln to use usb high-speed instead of super-speed with recent changes, I noticed while testing this. Otherwise it crashed. I'd like to submit that separately, but I'm not sure what's best. 

The options I see are:
1. copy my wip device tree from sdm845-mainline to the upstream folder
2. copy my wip device tree from sdm845-mainline to a u-boot-specific devicetree
3. only change the usb in the upstream folder
4. only change the usb and make a new u-boot-specific-devicetree

Please let me know what would be the best way to proceed with this.

Thanks,
Paul Sajna
