Bryan O'Donoghue 8c81d4608d greybus: interface: Extract and store Interface feature byte ... The Interface description in the Greybus specification contains a 'features' field which is currently not implemented on the AP side. The Interface features field provides information on optional attributes of an Interface as a bitmask. Currently only GREYBUS_INTERFACE_FEATURE_TIMESYNC is implemented in the specification but, the expectation is that other feature flags will be added over time. This patch adds support to extract the feature byte communicated in the features field of the Interface Descriptor header and extends struct interface to contain a features field through which any user with a pointer to struct interface may interrogate the features of an Interface. This is a necessary pre-cursor for TimeSync to ensure only Interfaces which declare GREYBUS_INTERFACE_FEATURE_TIMESYNC will be included when we go through the process of FrameTime synchronization.
