power: qpnp-qnovo5: Add driver to support Qnovo5 



Qnovo5 is a PBS based pulse charging engine which has different
pulse train pattern and register mapping with the legacy Qnovo
module. Add the driver to export the registers of the hardware
module and the parameters of the charging status to allow the
userspace code to diagnose and control the charging phase.

QPNP Qnovo5 pulse engine



QPNP Qnovo5 is a PBS based pulse charging engine which works in tandem with the

QPNP SMB5 Charger device. It configures the QPNP SMB5 charger to

charge/discharge as per pulse characteristics.



The QPNP Qnovo5 pulse engine has a single peripheral assigned to it.



Properties:

- compatible:

  Usage:      required

  Value type: <string>

  Definition: It must be "qcom,qpnp-qnovo5".



- reg:

  Usage:      required

  Value type: <u32>

  Definition: Specifies the base address of the module. Qnovo5 is using a

		SDAM peripheral so this is the address of the SDAM module

		being used.



- interrupts:

  Usage:      required

  Value type: <prop-encoded-array>

  Definition: Specifies the interrupt associated with Qnovo5.



- interrupt-names:

  Usage:      required

  Value type: <string>

  Definition: Specifies the interrupt name for Qnovo5. There is only one

		interrupt named as "ptrain-done".



Example:



qcom,qpnp-qnovo@b000 {

	compatible = "qcom,qpnp-qnovo5";

	reg = <0xb000 0x100>;

	interrupts = <0x2 0xb0 0x0 IRQ_TYPE_NONE>;

	interrupt-names = "ptrain-done";

};
