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.

usb: typec: fusb302: Populate tcpc fwnode for TCPM property handling

2018-09-20T10:56:02Z

This update populates the tcpc handle's fwnode pointer with the child usb-connector node, if it exists, so that TCPM can perform generic property handling to define the ports capabilities.

USB: typec: fsusb302: remove unused variables snk_pdo and toggling_mode_name

2018-09-10T18:01:04Z

Variables snk_pdo and toggling_mode_name are defined but are not used and hence can be removed. Cleans up clang warnings: warning: 'snk_pdo' defined but not used [-Wunused-const-variable=] warning: 'toggling_mode_name' defined but not used [-Wunused-const-variable=] Signed-off-by: Colin Ian King Reviewed-by: Guenter Roeck Reviewed-by: Heikki Krogerus Signed-off-by: Greg Kroah-Hartman

USB: typec: fsusb302: Drop empty set_current_limit implementation

2018-07-02T16:08:19Z

The set_current_limit tcpm_dev callback is optional and the tcpm core will already log the passed in values, so there is no need to have an empty implementation of this. Signed-off-by: Hans de Goede Reviewed-by: Guenter Roeck Signed-off-by: Greg Kroah-Hartman

USB: typec: fsusb302: no need to check return value of debugfs_create_dir()

2018-05-31T14:03:59Z

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Clean up the fsusb302 driver to not care if the root directory was created, as the code should work properly either way.

usb: typec: fusb302: Fix debugfs issue

2018-05-24T16:17:00Z

Removing the "fusb302" debugfs directory when unloading the driver. That allows the driver to be loaded more then one time. The directory will not get actually removed until it is empty, so only after the last instance has been removed. This fixes an issue where the driver can't be re-loaded if it has been unloaded as the "fusb302" debugfs directory already exists.

typec: tcpm: Represent source supply through power_supply

2018-04-25T12:20:20Z

This commit adds a power_supply class instance to represent a PD source's voltage and current properties. This provides an interface for reading these properties from user-space or other drivers. For PPS enabled Sources, this also provides write access to set the current and voltage and allows for swapping between standard PDO and PPS APDO. As this represents a superset of the information provided in the fusb302 driver, the power_supply instance in that code is removed as part of this change, so reverting the commit titled 'typec: tcpm: Represent source supply through power_supply class' Signed-off-by: Adam Thomson Reviewed-by: Guenter Roeck Reviewed-by: Heikki Krogerus Signed-off-by: Greg Kroah-Hartman

usb: typec: fusb302: remove max_snk_* for sink config

Since max_snk_* is to be deprecated, so remove max_snk_* by adding a variable PDO for sink config. Reviewed-by: Hans de Goede Signed-off-by: Li Jun Reviewed-by: Guenter Roeck Acked-by: Heikki Krogerus Signed-off-by: Greg Kroah-Hartman

Remove the unused (not implemented anywhere) tcpc_mux_dev abstraction and replace it with calling the new typec_set_orientation, usb_role_switch_set and typec_set_mode functions.
