From: ChiYuan Huang <cy_huang@richtek.com>

This patch series is to enable Richtek RTQ6056 support.

The RTQ6056 is a high accuracy current-sense monitor with I2C interface, and
the device provides full information for system by reading out the load current
and power.

Since v2
- Change the resistor property name to be generic 'shunt-resistor-micro-ohms'.
- Rename file from 'rtq6056-adc' to 'rtq6056'.
- Refine the ABI, if generic already defined it, remove it and check the channel
report unit.
- Add copyright text.
- include the correct header.
- change the property parsing name.
- To use iio_chan_spec address field.
- Refine each channel separate and shared_by_all.
- Use pm_runtime and pm_runtime_autosuspend.
- Remove the shutdown callback. From the HW suggestion, it's not recommended to
use battery as the power supply.
- Check all scale unit (voltage->mV, current->mA, power->milliWatt).
- Use the read_avail to provide the interface for attribute value list.
- Add comma for the last element in the const integer array.
- Refine each ADC label text.
- In read_label callback, replace snprintf to sysfs_emit.
