usb: typec: nb7vpq904m: Add an error handling path in nb7vpq904m_probe()

2023-08-04T12:56:07+00:00

In case of error in the nb7vpq904m_probe() probe function, some resources
need to be freed, as already done in the remove function.

Add the missing error handling path and adjust code accordingly.

usb: typec: intel_pmc_mux: Configure Active and Retimer Cable type

2023-07-25T16:20:42+00:00

Cable type such as active and retimer received as a part of Thunderbolt3
or Thunderbolt4 cable discover mode VDO needs to be configured in the
thunderbolt alternate mode.

Configuring the register bits for this cable type is changed with Intel
Meteor Lake platform. BIT2 for Retimer/Redriver cable and BIT22 for
Active/Passive cable.

usb: typec: intel_pmc_mux: Add new ACPI ID for Lunar Lake IOM device

2023-07-25T16:13:48+00:00

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.

Added IOM_PORT_STATUS_REGS macro for using platform specific IOM port
status offset and size.

struct i2c_driver::probe_new is about to go away. Switch the driver to

usb: typec: nb7vpq904m: fix CONFIG_DRM dependency

2023-06-23T07:54:45+00:00

With the following config set:
CONFIG_DRM=m
CONFIG_DRM_PANEL=y
CONFIG_DRM_BRIDGE=y
CONFIG_DRM_PANEL_BRIDGE=y
CONFIG_TYPEC_MUX_NB7VPQ904M=y

vmlinux fails on the following symbols:
  ld.lld: error: undefined symbol: devm_drm_bridge_add
  ld.lld: error: undefined symbol: devm_drm_of_get_bridge

Add dependendy on DRM || DRM=no since CONFIG_DRM dependency is optional
and guarded by:
IS_ENABLED(CONFIG_OF) && IS_ENABLED(CONFIG_DRM_PANEL_BRIDGE)
in the drive.

Also add "select DRM_PANEL_BRIDGE if DRM" to clarify DRM_PANEL_BRIDGE
is required if CONFIG_DRM is enabled.

usb: typec: fsa4480: add support for Audio Accessory Mode

2023-06-21T16:07:55+00:00

The FSA4480 Type-C switch supports switching the Audio R/L,
AGND and MIC signals to the USB-C DP/DM and SBU1/2 to support
the Audio Accessory Mode.

The FSA4480 has an integrated Audio jack detection mechanism
to automatically mux the AGND, MIX and Sense to the correct
SBU lines to support 3 pole and both 4 pole TRRS pinouts.

usb: typec: fsa4480: rework mux & switch setup to handle more states

2023-06-21T16:07:55+00:00

In order to handle the Audio Accessory mode, refactor the mux
and switch setup in a single function.

The refactor will help add new states and make the process
simpler to understand.

usb: typec: add support for the nb7vpq904m Type-C Linear Redriver

2023-06-15T10:41:18+00:00

Add support for the ON Semiconductor NB7VPQ904M Type-C USB SuperSpeed
and DisplayPort ALT Mode Linear Redriver chip found on some devices
with a Type-C port.

The redriver compensates ultra High-Speeed DisplayPort and USB
Super Speed signal integrity losses mainly due to PCB & transmission
cables.

The redriver doesn't support SuperSpeed lines swapping, but
can support Type-C SBU lines swapping.
