This patchset > has been blocked for a long time now, can we get that merged soonish > somehow ? Sorry, it slipped through the cracks. I posted this as a fix for SCMI which we fixed it later. This got de-prioritised in my todo list. Sorry for that. I think main problem I had is to write a proper select statement in YAML scheme to check the DT nodes when it is present. I couldn't get anything similar for reference from clocks. I had "select: false" which I knew was not acceptable as it can't go throw dt_bindings_check. I am happy if someone wants to pick up and work on that to push the change or provide suggestions that I can try out. I am unable to spend more time trying to understand whole YAML schema ATM. -- Regards, Sudeep _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
