This pulse synchronizes the start of the DMAs and Codec Interfaces for the audio usecases and can serve as a periodic wakeup source for the DSP. This series adds the DT binding and driver support to model this rate generator as a clock provider, and extends the VA macro binding with a new hawi variant that consumes the heartbeatpulse clock alongside its existing mclk, macro, and dcodec clocks. Patch 1 adds the YAML binding for the new qcom,hawi-lpass-va-csr clock provider node and extends qcom,lpass-va-macro to describe the new qcom,hawi-lpass-va-macro compatible with its four-clock constraint. Patch 2 adds the lpass-va-csr driver that registers the lpass_heartbeat_pulse clock and enables/disables the rate generator via regmap when the clock consumer requests it.
