From: ChiYuan Huang <cy_huang@xxxxxxxxxxx> 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 v4 - Add '__aligned(8)' for timestamp member. - Declare timestamp from 'int64_t' to more unified 's64'. Since v3 - change the node name to be generic 'adc' in binding example. - Refine pm_runtime API calling order in 'read_channel' API. - Fix vshunt wrong scale for divider. - Refine the comment text. - Use 'devm_add_action_or_reset' to decrease the code usage in probe function. - Use RUNTIME_PM_OPS to replace SET_RUNTIME_PM_OPS. - minor fix for the comma. - Use pm_ptr to replace the direct assigned pm_ops. 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.
