- reg: Base address and size of SAI common register set.
- clocks: Must contain phandle and clock specifier pairs for each entry
in clock-names.
- clock-names: Must contain "x8k" and "x11k"
- clock-names: Must contain "pclk" "x8k" and "x11k"
"pclk": Clock which feeds the peripheral bus interface.
Mandatory for "st,stm32h7-sai" compatible.
Not used for "st,stm32f4-sai" compatible.
"x8k": SAI parent clock for sampling rates multiple of 8kHz.
"x11k": SAI parent clock for sampling rates multiple of 11.025kHz.
- interrupts: cpu DAI interrupt line shared by SAI sub-blocks
Optional properties:
- resets: Reference to a reset controller asserting the SAI
- st,sync: specify synchronization mode.
By default SAI sub-block is in asynchronous mode.
This property sets SAI sub-block as slave of another SAI sub-block.
Must contain the phandle and index of the sai sub-block providing
the synchronization.
SAI subnodes:
Two subnodes corresponding to SAI sub-block instances A et B can be defined.
