Public bug reported: [Impact] the following two upstream patches break mediatek downstream regulator device tree setup: d3cf8a17498d regulator: mt6360: De-capitalize devicetree regulator subnodes 1e0fb1136461 power: supply: mt6360_charger: Fix of_match for usb-otg-vbus regulator
[Fix] in order to maintain the device tree compatibility, the kernel has to support both upstream and downstream device tree compatible strings. [Test] check if the downstream device tree nodes are still able to be probed. [Where problems could occur] the default behavior is to use upstream device tree compatibility strings, so the issue might arise if the downstream device tree nodes are not probed correctly. however, this is unlikely unless the user mixes the upper and lower case of nodes.
