If we write registers very fast we can endup in a situation where some of the writes will be dropped without any notice.
So wait for the fifo space to be available before reading/writing the soundwire registers.
Out of curiosity, do you actually need to do a check in the read case as well?
Yes, This is just to make sure the read command is finished and fifo is ready with data.
If not we will be reading quickly an empty fifo!
The commit message talks about writes getting dropped, is the opposite also a problem?
Its highly likely, for safety I have added support for both write and read waits in this patch.
