"rx" for "st,sti-uni-reader" compatibility
- st,version: IP version integrated in SOC.
- dai-name: DAI name that describes the IP.
- st,mode: IP working mode depending on associated codec.
"HDMI" connected to HDMI codec and support IEC HDMI formats (player only).
"SPDIF" connected to SPDIF codec and support SPDIF formats (player only).
"PCM" PCM standard mode for I2S or TDM bus.
"TDM" TDM mode for TDM bus.
Required properties ("st,sti-uni-player" compatibility only):
- clocks: CPU_DAI IP clock source, listed in the same order than the
CPU_DAI properties.
- st,uniperiph-id: internal SOC IP instance ID.
Optional properties:
- pinctrl-0: defined for CPU_DAI@1 and CPU_DAI@4 to describe I2S PIOs for
external codecs connection.
- pinctrl-names: should contain only one value - "default".
- st,tdm-mode: to declare to set TDM mode for unireader and uniplayer IPs.
Only compartible with IPs in charge of the external I2S/TDM bus.
Should be declared depending on associated codec.
