I2S in samsung audio subsytem has a small internal dma(idma). IDMA can be used in low power audio mode and I2S0 secondary fifo data tranfer. In this patchsets, idma driver is added. Original code is made by jassi brar on SMDKV210 After idma driver merge, I will submit low power audio support with idma driver and samsung dsp driver.
Changes since v1: 1. Change idma_new by new pcm_new api 2. Add handling different idma address 3. As jassi comments, Modify the idma driver
This patchset contains followings
