Hi, v1: https://lore.kernel.org/linux-usb/20210918120934.28252-1-sven@xxxxxxxxxxxxx/ Thanks again to everyone for your review of the initial version! This series adds initial support for the Apple CD3217/3218 chip which is also known as Apple ACE1/2. These chips are used on Apple M1 machines. They are based on the TI TPS6598x chips with a few differences: - The interrupt numbers have been changed - The secondary i2c bus and its interrupt controller are connected to the system management controller and must not be disturbed - The chip comes up in a low power state and must be booted using the "SPSS" (System Power State Switch maybe) command which is not documented in the TI manual - The interrupt mask must be set up explicitly As suggested bei Heikki, this is now done by creating a separate interrupt handler for the Apple chips and adding specific setup code to the probe function. There should be no functional changes for existing TPS chips which is which I've removed the RFT.
