[PATCH 0/2] ASoC: Add LPASS VA CSR HeartBeat pulse clock support

[Sarath Ganapathiraju via B4 Relay <devnull+sarath.ganapathiraju.oss.qualcomm.com@kernel.org>]

The LPASS VA CSR block contains rate generator hardware that produces
a HeartBeat Pulse (also known as RateGen Pulse). 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.
