It does not look like you tested the DTS against bindings. Please run `make dtbs_check W=1` (see Documentation/devicetree/bindings/writing-schema.rst or https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/ for instructions).

I'll test the DTS against bindings and update it in patch series v2.

Use gpio-leds to configure GPIOW5 to GPIO_ACTIVE_HIGH and GPIO_TRANSITORY flags as a bmc ready led. The GPIOW5 pin is reset when watchdog timeout occurs. Configure the GPIOS3 to GPIO_ACTIVE_HIGH as an identify led.
