usb: typec: ucsi: add support for Cypress CCGx

2018-11-09T17:49:59Z

Latest NVIDIA GPU cards have a Cypress CCGx Type-C controller over I2C interface. This UCSI I2C driver uses I2C bus driver interface for communicating with Type-C controller. Signed-off-by: Ajay Gupta Acked-by: Heikki Krogerus Signed-off-by: Wolfram Sang

usb: typec: tcpm: Report back negotiated PPS voltage and current

2018-10-09T14:05:41Z

Currently when requesting a specific voltage or current through the psy interface, for PPS, when reading back from that interface the values will always be the same as previously given, if the request was successful. However PPS only allows for 20mV voltage steps and 50mA current steps, and the psy class expects microvolt and micro amp requests, so inbetween values can be provided through this interface. Really when reading back the true values negotiated should be given, and not the ones originally asked for. To report the actual values negotiated with the Source, the values stored are now rounded down to the relevant step units prior to building the PPS request, so that those values are later correctly reported through the psy interface. In addition this improves the adjustments made to meet the operating power requirements of the platform, which previously could have been slightly out due to not using valid PPS units of voltage and current.

usb: typec: tcpm: Fix APDO PPS order checking to be based on voltage

2018-10-02T19:05:30Z

Current code mistakenly checks against max current to determine order but this should be max voltage. This commit fixes the issue so order is correctly determined, thus avoiding failure based on a higher voltage PPS APDO having a lower maximum current output, which is actually valid.

usb: typec: fusb302: Resolve fixed power role contract setup

2018-09-28T13:08:09Z

When the controller is configured for a fixed power role (Source only or Sink only), attach does not proceed within the TCPM state machine as there is no CC event generated by this driver to update the CC line status. To rectify this, when CC is configured as Source or Sink we now make use of the hardware's automatic fixed Source or Sink toggling mechanism, which detects attaches in the same way as for DRP toggling. In this way the result of toggling is handled in the same way by the 'fusb302_handle_togdone()' function, and CC events are generated as expected for TCPM allowing a contract to be established.

usb: typec: fusb302: reorganizing the probe function a little

2018-09-20T11:37:29Z

The debugfs needs to be initialized as the last step in probe in this case. The struct dentry *rootdir can't be pointing to anything unless driver probe really finishes successfully. It is also not necessary to clear the i2c clientdata if the probe fails, so removing the extra label used for that.
