usb: typec: fsa4480: Add support to swap SBU orientation

2023-10-27T10:54:29+00:00

On some hardware designs the AUX+/- lanes are connected reversed to
SBU1/2 compared to the expected design by FSA4480.

Made more complicated, the otherwise compatible Orient-Chip OCP96011
expects the lanes to be connected reversed compared to FSA4480.

* FSA4480 block diagram shows AUX+ connected to SBU2 and AUX- to SBU1.
* OCP96011 block diagram shows AUX+ connected to SBU1 and AUX- to SBU2.

So if OCP96011 is used as drop-in for FSA4480 then the orientation
handling in the driver needs to be reversed to match the expectation of
the OCP96011 hardware.

Support parsing the data-lanes parameter in the endpoint node to swap
this in the driver.

The parse_data_lanes_mapping function is mostly taken from nb7vpq904m.c.

usb: typec: intel_pmc_mux: enable sysfs usb role access

2023-10-02T11:54:42+00:00

The OS, such as ChromeOS, uses Android Runtime to run Android applications.
This necessitates supporting tools, for example, Android Debugger (ADB).
On host to host setup xHC.DbC shall support ADB with USB. This requires
user space to control USB roles.

Enable user space control to modify the USB Type-C role. At run time
it will create a role attribute in /sys/class/usb_role//.
Attribute can be modified based on the values suggested in the
Documentation/ABI/testing/sysfs-class-usb_role.

Intel Lunar Lake IOM has a different IOM port status offset and size
than Intel MTL.

Intel Lunar Lake is the first platform to extend IOM port status
from 32bit to 64bit by adding DDI port number into IOM port status.
