…WCN39xx WCN3990 and other similar WiFi/BT chips incorporate a simple on-chip PMU (clearly described as such in the documentation). Provide DT schema covering other Qualcomm WiFi/BT chips to cover these devices too.

The WCN39xx family of WiFi/BT chips incorporates a simple PMU, spreading voltages over internal rails. Implement power sequencing support for this generation of WCN chips. Unlike later devices, they don't have separate enable GPIO lines, letting the chip figure out the necessary parts on its own.

The WCN39xx family of WiFi/BT chips incorporates a simple PMU, spreading voltages over internal rails. Implement support for using powersequencer for this family of QCA devices in addition to using regulators.

This series brings upstream power sequencing support for the WCN39xx
family of WiFi/BT chips (WCN3988, WCN3990, WCN3991, WCN3998).
The WCN39xx family incorporates a simple on-chip PMU that spreads
voltages over internal rails. Unlike later WCN devices, they have no
separate enable GPIO lines and rely on the chip to handle power
sequencing internally.
Changes:
regulator: dt-bindings: Add DT schema for qcom,wcn3990-pmu covering
the WCN39xx PMU
power: sequencing: qcom-wcn: Implement power sequencer driver support
for WCN39xx
Bluetooth: qca: Enable pwrseq as an alternative to regulators for
WCN39xx devices
