|
-Required properties:
|

-- compatible: 'amlogic,axg-toddr' or
|
|
- 'amlogic,axg-toddr' or
|
|
- 'amlogic,g12a-frddr' or

- 'amlogic,g12a-toddr' or

- 'amlogic,sm1-frddr' or

|
|
-- reg: physical base address of the controller and length of memory
|
|
- mapped region.
|
|
-- interrupts: interrupt specifier for the fifo.
|
|
-- clocks: phandle to the fifo peripheral clock provided by the audio
|
|
- clock controller.
|
|
-- resets: list of reset phandle, one for each entry reset-names.
|
|
-- reset-names: should contain the following:
|
|
- * "arb" : memory ARB line (required)
|
|
- * "rst" : dedicated device reset line (optional)
|
|
-- #sound-dai-cells: must be 0.
|
|
-- amlogic,fifo-depth: The size of the controller's fifo in bytes. This
|
|
- is useful for determining certain configuration such
|
|
- as the flush threshold of the fifo
|
|
-
|
