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/ Changes since v2: - Fixed comments from Rob - Fixed DT schema warnings.
