One of the current rk3308 'i2s' nodes has a different dma layout with only 1 item. Table 9-2 DMAC1 Request Mapping Table shows that there 2 dma sources available, so fix the dmas and dma-names for the rk3308 'i2s' node. 10 I2S/PCM_2CH_1 tx High level 11 I2S/PCM_2CH_1 rx High level
...however table 1-5 in the same manual (at least that I could find) says request 10 is reserved. Does that mean it was intended to be wired up for this, but ended up broken for some reason?
Do you have hardware to confirm whether this works reliably or not? Robin.
