Subject: [PATCH v3 0/6] usb: typec: tipd: Add Apple M1 support
Date: Tue, 28 Sep 2021 17:54:56 +0200	[thread overview]
Message-ID: <20210928155502.71372-1-sven@svenpeter.dev> (raw)

Hi,

v1: https://lore.kernel.org/linux-usb/20210918120934.28252-1-sven@svenpeter.dev/
v2: https://lore.kernel.org/linux-usb/20210923181321.3044-1-sven@svenpeter.dev/ 
Thanks again to Heikki for your review of v2!

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

The only difference to v2 is that now of_device_is_compatible instead of
of_device_get_match_data is used to switch to the CD321x logic as suggested
by Heikki.

Best,

Sven
