As discussed this change breaks the DT backward compatibility but it allows to not depend on TISCI firmware properties in DT node. IMHO, this will ensure that any future changes will not effect DT properties. This series depends on the the new Yaml bindings for common TISCI[1] [0] https://lore.kernel.org/linux-arm-kernel/20190923042405.26064-1-lokeshvutla@ti.com/ [1] https://patchwork.kernel.org/patch/11676843/ Tested with: - DT_SCHEMA_FILES="Documentation/devicetree/bindings/interrupt-controller/ti,sci-intr.yaml" v8make dt_binding_check - DT_SCHEMA_FILES="Documentation/devicetree/bindings/interrupt-controller/ti,sci-inta.yaml" v8make dt_binding_check - DT_SCHEMA_FILES="Documentation/devicetree/bindings/interrupt-controller/ti,sci-intr.yaml" v8make dtbs_check - DT_SCHEMA_FILES="Documentation/devicetree/bindings/interrupt-controller/ti,sci-inta.yaml" v8make dtbs_check Changes since v4: - Fixed Rob's comment on INTR and INTA yaml documentation - Collected Reviewed-by's and Acked-by's Changes since v3: - Hardcode param_count based on parent instead of reading it from DT. - Drop storing TISCI device id in platform device id field. Changes since v2: - Fixed comments from Rob - Fixed DT schema warnings. Changes since v1: - Rebased on top of latest Linux master - Dropped DT patches.
