| | | | | | | | | | | | Currently everytime we get the following message on boot: fsl-ssi-dai 202c000.ssi: could not get baud clock: -2 This is not really useful information to get on every boot, so make it a debug message instead.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch defines the appropriate register values for different oparation modes and IP versions. We have to handle DMA/FIQ, AC97, DEBUG-IRQs and offline/online configuration support. With this patch we cleanup some driver code that was not reference manual conform and try to cleanup the whole trigger function to seperate the actual register values from the enable/disable logic, which is now hidden in fsl_ssi_config helpers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a struct 'fsl_ssi_rxtx_reg_val' which holds register values necessary to enable rx/tx. Based on those preset register values, the added configuration functions will cleanly enable/disable different parts of the SSI IP while supporting online/offline configuration. Different operating modes can be setup directly as different register values in fsl_ssi_reg_val. These functions and structs will help to cleanup and simplify the trigger function to support many different IP versions (online/offline configuration) and different operating modes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a small but significant difference between imx21-ssi and imx51-ssi and above. imx21-ssi does not allow online reconfiguration of some registers. They have to be configured at the beginning. imx51-ssi has to reconfigure the SSI unit while it is running. Otherwise it would not be possible to have two streams in parallel. The new SDMA unit in imx51 and above has to be configured before the first DMA request arrives. Therefor we need to setup TDMAE/RDMAE just before starting the stream. This patch introduces distinct imx51-ssi as compatible and adds of_device_id matching in the probe function.

Instead of imx-pcm-audio, in this case imx-pcm-fiq-audio device is added and the SIER flags are set differently. We need imx-pcm-fiq for some boards that use an incompatible codec. imx-pcm-fiq handles those codecs differently and allows to operate with them. DMA is not possible because some data sent by the codecs, e.g. wm9712, is not in the datastream. Also some data is mixed up in the fifos, so that we need to sort them out manually.

The dma_params struct gets passed to the pcm driver from the dai driver. Instead of going this route of indirection embed the dma_data struct directly into the dma_params struct and let the dai driver fill it in.
