2022-11-12	i2c: /pasemi: PASemi I2C controller IRQ enablement	Arminder Singh
	This patch adds IRQ support to the PASemi I2C controller driver to increase the performace of I2C transactions on platforms with PASemi I2C controllers. While primarily intended for Apple silicon platforms, this patch should also help in enabling IRQ support for older PASemi hardware as well should the need arise. This version of the patch has been tested on an M1 Ultra Mac Studio, as well as an M1 MacBook Pro, and userspace launches successfully while using the IRQ path for I2C transactions.

2021-10-11	i2c: pasemi: Add Apple platform driver	Sven Peter
	With all the previous preparations we can now finally add the platform driver to support the PASemi-based controllers in Apple SoCs. This does not work on the M1 yet but should work on the early iPhones already.
