Hi Daniel
The simple-card driver currently hard-codes the clk_id parameter in snd_soc_dai_set_sysclk() to 0. Make this configrable for both CPU and codec dai sub-nodes.
This still has the limitation that only one clk_id can be configured, but it should help some more platforms to use simple-card in favor to a more specific machine driver.

- system-clock-direction-out : specifies clock direction as 'out' on initialization. It is useful for some aCPUs with fixed clocks.
+- system-clock-index : index of the system clock to use when
the mclk frequency is on the CPU/CODECDAI. Defaults to 0.
I'm not a DT guy, but I think DT doesn't want to have index directly ? I don't know detail, but I guess DT want to have like
system-mclock = <&xxxx 3>
