11*ae5de77eSEmmanuel Vadotdescription:
12*ae5de77eSEmmanuel Vadot  This UART uses a subset of the PL011 registers and consequently lives in the
13*ae5de77eSEmmanuel Vadot  PL011 driver. It's baudrate and other communication parameters cannot be
14*ae5de77eSEmmanuel Vadot  adjusted at runtime, so it lacks a clock specifier here.
