The first "S" in SBSA stands for "Server". I don't think it makes sense to put an SBSA watchdog device in a non-server SOC. Frankly, I don't understand why people want to make this driver work on hardware that doesn't exist. The SBSA is intended for 64-bit ARM Servers that use ACPI. Yes, there are a couple of ARM64 servers that use device tree, but those are legacy platforms. -- Qualcomm Innovation Center, Inc.
