now I'm working on ESAI driver for uboot on imx6solox, I want to use sdma for the audio data transfer.

I found some example in the platform SDK 1.1 and port sdma part to uboot. but when I call sdma_init() I always got fail because of buffer descriptor flags SDMA_FLAGS_BUSY always set in function sdma_load_init_script(),

is there anything need to be done before I call sdma_init() such as clock setting?
