Compatibles can come in two formats. 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 <krzysztof.kozlowski@xxxxxxxxxx> --- Changes since v3: 1. Add qcom,kpss-wdt-xxx to pattern for exceptions. 2. Add ipq806x entries to list of exceptions. Changes since v2: 1. Narrow the expected pattern to be followed by dash '-' after model number (msm8996-) or by two letters and a dash (sc8280xp-). 2. Add qcom,apss-wdt-xxx to list of exceptions. 3. Use comment instead of description in the oneOf list. Changes since v1: 1. Add schema instead of readme (Rob).
