IMX6SL-EVK EINK Can't work

[bruce_chen]

Dear All:

          Now I am use IMX6SL-evk for eink display, but compile successed and use mfgtool download image to board, the eink can't display,  the bootargs not set  "video=mxcepdcfb:E060SCM,bpp=16"  because if i am set it, the system can't running. The log message has DMA error, I don't know why the DMA error, like below:

max17135 0-0048: PMIC MAX17135 for eInk display
i2c i2c-0: IMX I2C adapter registered
i2c i2c-0: can't use DMA
i2c i2c-1: IMX I2C adapter registered
i2c i2c-1: can't use DMA
i2c i2c-2: IMX I2C adapter registered
i2c i2c-2: can't use DMA
Linux video capture interface: v2.00

I think the DMA error, so the eink not working. this is only myself point,  very thanks.

 the console full  logout like below:
