+/**
+*
+* @file xv_letterbox_l2.h
+*
+* This header file contains layer 2 API's of the letter box sub-core driver.
+* The functions contained herein provides a high level implementation of
+* features provided by the IP, abstracting away the register level details from
+* the user
+*
+* <b>Letter Box IP Features </b>
+*
+* This Letterbox IP supports following features
+* 	- Apply black bars (horizontal or vertical) on input stream
+* 	- Programmable background colors
+* 	- up to 16bits color depth
+*	- 1, 2 or 4 pixel per clock processing
+*	- Input stream up to 4k2k 60Hz
+*
+* <b>Dependency</b>
+*
+* This driver makes use of the video enumerations and data types defined in the
+* Xilinx Video Common Driver (video_common_vX.x) and as such the common driver
+* must be included as dependency to compile this driver
+
+* <b>Initialization & Configuration</b>
+*
+* The device driver enables higher layer software (e.g., an application) to
+* communicate to the lbox core.
+*
+* Before using the layer-2 API's user must initialize the core by calling
+* Layer-1 API XV_letterbox_Initialize(). This function will look for a
+* configuration structure for the device and initialize it to defined HW
+* settings. After initialization Layer-2 API's can be used to configure
+* the core. It is recommended user always make use of Layer-2 API to
+* interact with this core.
+* Advanced users always have the capability to directly interact with the IP
+* core using Layer-1 API's that perform low level register peek/poke.
+*
+* <b> Interrupts </b>
+*
+* This driver does not have any interrupts
+*
+* <b> Virtual Memory </b>
+*
+* This driver supports Virtual Memory. The RTOS is responsible for calculating
+* the correct device base address in Virtual Memory space.
+*
+* <b> Threads </b>
+*
+* This driver is not thread safe. Any needs for threads or thread mutual
+* exclusion must be satisfied by the layer above this driver.
