18 * vpss - video processing subsystem module header file.
20 * Include this header file if a driver needs to configure vpss system
21 * module. It exports a set of library functions for video drivers to
22 * configure vpss system module functions such as clock enable/disable,
23 * vpss interrupt mux to arm, and other common vpss system module
24 * functions.
