[PATCH 0/2] ASoC: xilinx: xlnx_i2s: Discover parameters from registers

[Sean Anderson]

Xilinx helpfully included a read-only "config" register that contains
configuration parameters. Discover our parameters from this register
instead of reading them from the device tree.

[PATCH 1/2] dt-bindings: sound: xlnx,i2s: Make discoverable parameters optional

[Sean Anderson]

These parameters can be discovered from a config register. As they will
not be used any more, mark them deprecated, make them optional, and
remove them from the example.
