This series of patch adds the possibility to set these limits from sysfs. Also, the AXP223 PMIC shares most of its behaviour with the AXP221 but the former can set the VBUS power supply max current to 100mA, unlike the latter. The AXP223 VBUS power supply driver used to probe on the AXP221 compatible. This series of patch introduces a new compatible for the AXP223 to be able to set the current max limit to 100mA. With that new compatible, boards having the AXP223 see their DT updated to use the VBUS power supply driver with the correct compatible. This series of patch also migrates from of_device_is_compatible function to the data field of of_device_id to identify the compatible used to probe. This improves the code readability.
