usb: typec: Use sysfs_emit_at when concatenating the string

2023-07-25T15:45:29+00:00

The buffer address used in sysfs_emit should be aligned to PAGE_SIZE.
Use sysfs_emit_at instead to offset the buffer.

usb: typec: Iterate pds array when showing the pd list

2023-07-25T15:45:29+00:00

The pointers of each usb_power_delivery handles are stored in "pds"
array returned from the pd_get ops but not in the adjacent memory
calculated from "pd". Get the handles from "pds" array directly instead
of deriving them from "pd".

usb: typec: Set port->pd before adding device for typec_port

2023-07-25T15:45:29+00:00

When calling device_add in the registration of typec_port, it will do
the NULL check on usb_power_delivery handle in typec_port for the
visibility of the device attributes. It is always NULL because port->pd
is set in typec_port_set_usb_power_delivery which is later than the
device_add call.

Set port->pd before device_add and only link the device after that.

usb: typec: ucsi: move typec_set_mode(TYPEC_STATE_SAFE) to ucsi_unregister_partner()

2023-07-25T15:39:26+00:00

It's better to set TYPEC_STATE_SAFE mode from ucsi_unregister_partner()
instead of ucsi_partner_change(), ucsi_unregister_partner() is always
when the partner disconnects.

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)

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.

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
