Maulik Shah 83c4aba920 soc: qcom: rpmh-rsc: Enhance check for VRM in-flight request ... commit f592cc5794 upstream. Each RPMh VRM accelerator resource has 3 or 4 contiguous 4-byte aligned addresses associated with it. These control voltage, enable state, mode, and in legacy targets, voltage headroom. The current in-flight request checking logic looks for exact address matches. Requests for different addresses of the same RPMh resource as thus not detected as in-flight. Add new cmd-db API cmd_db_match_resource_addr() to enhance the in-flight request check for VRM requests by ignoring the address offset. This ensures that only one request is allowed to be in-flight for a given VRM resource. This is needed to avoid scenarios where request commands are carried out by RPMh hardware out-of-order leading to LDO regulator over-current protection triggering.
