a36b777a40 dp: tx: When downshifting during link training, always issue training pattern 0. 
For compliance purposes, training pattern 0 needs to be sent between
downshifting of lane count and link rates.

83f6fe1f77 dp: rx: example: Set up handlers after core configuration has complete. 
Since the RX handler initialization functions assert that the core is of type
RX, the configuration initialization function must be called prior to the
handlers being set.

80eb9a43cd dp: Added TX/RX assertions on all API functions. 
Functions now assert the core context upon which they operate.

XDp_Tx* functions are meant to be used with the DisplayPort core in the TX mode
of operation.
XDp_Rx* functions are meant to be used with the DisplayPort core in the RX mode
of operation.

7b382d036f dp: TX/RX core type should operate on the XDp structure pointer. 
Rather than on the configuration structure pointer.

This makes it cleaner and easier to use as this function is an API function.

64a4f5378a dp: XDptx->XDp and XDprx->XDp. 
XDp is used as an argument for all API functions. If a user application uses a
deprecated structure, it is automatically converted to the top-level XDp
structure which contains either a XDp_Tx or XDp_Rx structure which corresponds
to the previous XDptx and XDprx.
This is done for back-wards compatability with the dptx driver to minimize user
effort in migrating to the new dp driver.
