2021-12-23drivers/intel/pmc_mux/conn: Change usb{23}_port_number fields to device pointersReka Norman
Currently, the pmc_mux/conn driver uses integer fields to store the USB-2 and USB-3 port numbers from the SoC's point of view. Specifying these as integers in the devicetree is error-prone, and this information can instead be represented using pointers to the USB-2 and USB-3 devices. The port numbers can then be obtained from the paths of the linked devices, i.e. dev->path.usb.port_id. Modify the driver to store device pointers instead of integer port numbers, and update all devicetrees using the driver. These are the mainboards affected (all are Intel TGL or ADL based): google/brya google/volteer intel/adlrvp intel/shadowmountain intel/tglrvp system76/darp7 system76/galp5 system76/lemp10 Command used to update the devicetrees: git grep -l "usb._port_number" src/mainboard/ | \ xargs sed -i \ -e 's/register "usb2_port_number" = "\(.*\)"/use usb2_port\1 as usb2_port/g' \ -e 's/register "usb3_port_number" = "\(.*\)"/use tcss_usb3_port\1 as usb3_port/g' BUG=b:208502191 TEST=Build test all affected boards. On brya0, boot device and check that the ACPI tables generated with and without the change are the same.

2020-05-28soc/intel/tigerlake: Implement soc_get_pmc_mux_device()Tim Wawrzynczak
The ChromeOS EC is adding new entries to its USBC.CONx devices (see later patch), and it needs to get access to the PMC.MUX device so that its ACPI path can be retrieved. This provides a weak function to return NULL for all Intel SoCs except for Tiger Lake, which locates the device if it is found in the devicetree.

2020-05-26drivers/intel/pmc_mux/con: Add new PMC MUX & CON chip driversTim Wawrzynczak
The Tiger Lake PMC device has a MUX device which is expected to be exposed in ACPI tables. The MUX device simply has a _HID and _DDN. The CON devices link the USB-2 and USB-3 port numbers (from SoC point of view) to the physical connector. They also have orientation options for the sideband (SBU) and USB High Speed signals (HSL), meaning that they can be fixed (i.e, another device besides the SoC controls the orientation, and effectively the SoC is following only CC1 or CC2 orientation), or they can follow the CC lines.
