usb: typec: Add plug num_altmodes sysfs attr

2020-11-18T12:15:58+00:00

Add a field to the typec_plug struct to record the number of available
altmodes as well as the corresponding sysfs attribute to expose this to
userspace.

This allows userspace to determine whether there are any
remaining alternate modes left to be registered by the kernel driver. It
can begin executing any policy state machine after all available
alternate modes have been registered with the connector class framework.

This value is set to "-1" initially, signifying that a valid number of
alternate modes haven't been set for the plug. The sysfs file remains
hidden as long as the attribute value is -1.

We re-use the partner attribute for number_of_alternate_modes since the
usage and name is similar, and update the corresponding *_show() command
to support both partner and plugs.

usb: typec: Add number of altmodes partner attr

2020-11-18T11:55:46+00:00

Add a user-visible attribute for the number of alternate modes available
in a partner. This allows userspace to determine whether there are any
remaining alternate modes left to be registered by the kernel driver. It
can begin executing any policy state machine after all available
alternate modes have been registered with the connector class framework.

This value is set to "-1" initially, signifying that a valid number of
alternate modes haven't been set for the partner.

Also add a sysfs file which exposes this attribute. The file remains
hidden as long as the attribute value is -1.

usb: typec: add typec_find_pwr_opmode

2020-10-02T13:30:31+00:00

This patch adds a function that converts power operation mode string into
power operation mode value.

It is useful to configure power operation mode through device tree
property, as power capabilities may be linked to hardware design.

usb: typec: Add data structure for Enter_USB message

2020-07-01T12:06:25+00:00

This data structure can be delivered to the mux drivers when
Enter_USB Message is used exactly the same way as the
Alternate Mode specific data structures are delivered to the
mux drivers when Enter Mode Messages are used.

The Enter_USB data structure shall have all details related
to the Enter_USB Message, most importantly the Enter_USB
Date Object that was used.
