2023-07-02T17:22:38+00:00

Pull i2c updates from Wolfram Sang:

 - I2C has now a co-maintainer taking care of the host drivers. Welcome
   Andi Shyti and have fun!

 - platform remove callback converted to return void in drivers

 - simplify drivers by using devm_clk_get_enabled()

 - introduce i2c_get_match_data() to avoid more boilerplate code
   (especially since the core stopped delivering an i2c_device_id)

 - and the usual bunch of driver updates

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: ucsi: call typec_set_mode on non-altmode partner change

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

Add support for calling typec_set_mode() for the DEBUG, AUDIO
accessory modes.

Let's also call typec_set_mode() for USB as default and SAFE
when partner is disconnected.

The USB state is only called when ALT mode is specifically
not specified by the partner status flags in order
to leave the altmode handlers setup the proper mode to
switches, muxes and retimers.

usb: typec: tcpm: fix cc role at port reset

2023-06-19T13:34:28+00:00

In the current implementation, the tcpm set CC1/CC2 role to open when
it do port reset would cause the VBUS removed by the Type-C partner.

This sets CC1/CC2 according to the default state of port to fix it.

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.

usb: typec: ucsi: Mark dGPUs as DEVICE scope

2023-06-14T08:47:11+00:00

power_supply_is_system_supplied() checks whether any power
supplies are present that aren't batteries to decide whether
the system is running on DC or AC.  Downstream drivers use
this to make performance decisions.

Navi dGPUs include an UCSI function that has been exported
since commit 17631e8ca2d3 ("i2c: designware: Add driver
support for AMD NAVI GPU").

This UCSI function registers a power supply since commit
992a60ed0d5e ("usb: typec: ucsi: register with power_supply class")
but this is not a system power supply.

As the power supply for a dGPU is only for powering devices connected
to dGPU, create a device property to indicate that the UCSI endpoint
is only for the scope of `POWER_SUPPLY_SCOPE_DEVICE`.
