Either "vendor,ip-soc" or "vendor,soc-ip". Qualcomm bindings were mixing both of usages, so add a DT schema file documenting preferred policy and enforcing it for all new compatibles, except few existing patterns. Signed-off-by: Krzysztof Kozlowski --- Changes since v1: 1. Add schema instead of readme (Rob).
