Lina Iyer fef419c463 soc: qcom: rpmh: Remove serialization of TCS commands ... Requests sent to RPMH can be sent as fire-n-forget or response required, with the latter ensuring the command has been completed by the hardware accelerator. Commands in a request with tcs_cmd::wait set, would ensure that those select commands are sent as response required, even though the actual TCS request may be fire-n-forget. Also, commands with .wait flag were also guaranteed to be complete before the following command in the TCS is sent. This means that the next command of the same request blocked until the current request is completed. This could mean waiting for a voltage to settle or series of NOCs be configured before the next command is sent. But drivers using this feature have never cared about the serialization aspect. By not enforcing the serialization we can allow the hardware to run in parallel improving the performance. Let's clarify the usage of this member in the tcs_cmd structure to mean only completion and not serialization. This should also improve the performance of bus requests where changes could happen in parallel. Also, CPU resume from deep idle may see benefits from certain wake requests.
