imx6q-sabresd board: No "/dev/ipu" device

[garyyin]

Environment: IMX6Q SabreSD demo board. Yocto, L3.14.28, official.

The .sdcard image is generated by "bitbake fsl-image-qt5". All the code are official, no any change made.

I want to use IPU in the user space.  But no "/dev/ipu" device found.

ls /dev/i*

/dev/i2c-0  /dev/i2c-1  /dev/i2c-2  /dev/initctl

/dev/input:

by-id    event0  event2  event4  event6  event8  mouse0  mouse2

by-path  event1  event3  event5  event7  mice    mouse1

Hi Gary

there are several ipu drivers, seems this one will be as ../dev/mxc_ipu

as described in attached Linux Manual sect.6.2.3 IPU Device Driver.

Best regards

igor
