This series attempts to refactor the ACPI platform device creation code such that it may reused in the HiSilicon LPC driver. The topic was recently discussed at the following: https://lore.kernel.org/lkml/CAJZ5v0hkiOqhWyOcd2vjj-tcyHWB-cK=Dae-3sifhRfcbKWWGg@xxxxxxxxxxxxxx/ So first off I'll say that I am not advocating pursing the changes in this series, but just wanted to share to show others how it would look. Apart from requiring PNP driver changes, the API in acpi_create_platform_device_ops() ain't pretty. And also the PNP change means that the LPC uart changes from ttyS1 -> ttyS0, which would be a nuisance for anyone still using a board which uses the LPC UART. I have a separate change to show how the HiSilicon LPC driver would look by using platform_device_register_full() instead, and it is a lot neater: https://github.com/hisilicon/kernel-dev/commits/private-topic-lpc-6.0-platform-full Anyway, the commit messages should describe anything else needed to be known. Please share any comments, thanks.
