I'm aware that there are 2 IPU units on imx6. How can I use 2nd IPU unit?
This is in general how I currently use IPU:
// open IPU
int fd_ipu = open("/dev/mxc_ipu", O_RDWR, 0);
// use IPU
ioctl(fd_ipu, ..., ...);
// close IPU
Can this code be extended to differentiate between accessing 1st or 2nd IPU unit?
