Converting this into one DT schema would require several if statements, making the DT schema overall harder to read and understand. To avoid this, follow the example of SC7180/SC7280 and split "qcom,msm8916-mss-pil" (and the equivalent deprecated "qcom,q6v5-pil" compatible) into a separate DT schema. The schema is somewhat based on the one for SC7180/SC7280 but adjusted for the old platforms. Compared to the old plain text bindings, add missing documentation for the "bam-dmux" subnode and recommend one particular approach to specify the MBA/MPSS "memory-region" (the other one is marked as deprecated). Cc: Sireesh Kodali Signed-off-by: Stephan Gerhold --- Changes in v2: - Add blank lines between top-level properties - Drop "deprecated" in "oneOf" list, it is not clear if this is valid and it should be redundant since the properties itself are already marked as "deprecated" --- Like Sibi's patch series for SC7180/SC7820 [1] this is somewhat related to Sireesh's series that converts all of qcom,q6v5.txt [2] (with a lot of if statements). However, this series focuses on MSM8916/MSM8974 (or actually MSM8909) only.
