|
*
|
* This enum defines signal polarities and clock edge information for signals on
|
* a bus as bitmask flags.
|
*
|
* The clock edge information is conveyed by two sets of symbols,
|
* DRM_BUS_FLAGS_*_DRIVE_\* and DRM_BUS_FLAGS_*_SAMPLE_\*. When this enum is
|
* used to describe a bus from the point of view of the transmitter, the
|
* \*_DRIVE_\* flags should be used. When used from the point of view of the
|
* receiver, the \*_SAMPLE_\* flags should be used. The \*_DRIVE_\* and
|
* \*_SAMPLE_\* flags alias each other, with the \*_SAMPLE_POSEDGE and
|
* \*_SAMPLE_NEGEDGE flags being equal to \*_DRIVE_NEGEDGE and \*_DRIVE_POSEDGE
|
* respectively. This simplifies code as signals are usually sampled on the
|
* opposite edge of the driving edge. Transmitters and receivers may however
|
* need to take other signal timings into account to convert between driving
|
* and sample edges.
