ENGR00108640 IPUv3:support DP DC switch
1)Support dynamic switch between DP and DC.
2)Simplify some operation related with MXC v4l2 output.
Note:
For IPUv3, the switch is recommended to be done with
both LCD and TVout disabled.
Please flow these steps to switch DP from LCD to TVout.
1)echo U:720x480i-60 > /sys/class/graphics/fb1/mode
2)echo 1 > /sys/class/graphics/fb0/blank
3)echo 1 > /sys/class/graphics/fb1/blank
4)echo 1 > /sys/class/graphics/fb2/blank
5)echo 1-layer-fb >
/sys/class/graphics/fb0/fsl_disp_property
6)echo 0 > /sys/class/graphics/fb0/blank
7)echo 0 > /sys/class/graphics/fb1/blank
Please flow these steps to do the switching DP from
TVout to LCD.
1)echo U:720x480i-60 > /sys/class/graphics/fb1/mode
2)echo 1 > /sys/class/graphics/fb0/blank
3)echo 1 > /sys/class/graphics/fb1/blank
4)echo 1 > /sys/class/graphics/fb2/blank
5)echo 1-layer-fb >
/sys/class/graphics/fb1/fsl_disp_property
6)echo 0 > /sys/class/graphics/fb0/blank
7)echo 0 > /sys/class/graphics/fb1/blank
There are issues remain in these cases:
a.For IPUv3D
1)If both LCD and TVout are enabled and TVout uses DP,
disable/enable TVout will cause TVout display crash.
2)Not stable to run v4l output on DP-BG while DP is
used by TVout and LCD is on.
3)If either TVout or LCD is on, switching will cause
display issue on TVout and LCD.
b.For IPUv3EX
1)Not stable to run v4l output on DP-BG while DP is
used by TVout and LCD is on.
2)If both TVout and LCD are enabled, switching DP from
LCD to TVout will cause flick issue on TVout.
3)If TVout is enabled and LCD is disabled, switching
will cause flick issue on TVout.
