In the -current sources.
If you want to use test code, recompile kernel with ITE8181_LCD_CONTROL_ENABLE.
Or change ite8181_lcd_control_disable variable to 0 by gdb.
More infomation,  see arch/hpcmips/dev/ite8181.c.

I don't know why bad cases are exist....
Someone should rewrite these codes and fix this problem.
I have no time to fix this problem in these days.
