Adding support for: - DT bindings for the MBG thermal monitor peripheral on PM8775 - A new Qualcomm SPMI MBG thermal monitor driver under `drivers/thermal/qcom/` The driver monitors die temperature alarms, handles the MBG interrupt on upper-threshold violation, reads the fault status, and reports events to the thermal framework.
