Subject: [PATCH RFC 2/6] ASoC: dt-bindings: qcom,sm8250: Add clocks
properties for I2S
In order to describe the block and master clock of each I2S bus, add
the first 5 I2S busses clock entries.
The names (primary, secondary, tertiarty, quaternary, quinary) uses
the LPASS clock naming which were used for a long time on Qualcomm
LPASS firmware interfaces.
