Clock Modes for CSI2 Tx

These macros are used to set/get the clock mode in CSI2 Tx.

CCM - continuous clock mode. NCCM - non-continuous clock mode.

#define XCSI2TXSS_CCM   0
 
#define XCSI2TXSS_NCCM   1
 

Interrupt Types for setting Callbacks

These handlers are used to determine the type of the interrupt handler being registered with the MIPI CSI2 Tx Subsystem.

Since the subsystem is tightly coupled with the CSI2 Tx Controller driver, the handlers from the sub core are promoted to the subsystem level so that the application can use them.
