XCLKOUT mux register (0x10040a00) is not part of core clock SFR range, rather it is part of pmu-system-controller node.
One option would be to add a clock provider for XCLKOUT. That would require me to extend current clock driver to get the pmu-system-controller phandle which in turn is dependent on the patch to early initialize syscon driver.[1]
Will it be okay to configure XCLKOUT in snow sound-card driver by taking the phandle of pmu-system-controller from device tree? The implementation is provided below.
I can't think of any reason why we'd not want to have this visible as a clock? Ideally we don't want to have any ASoC specific clock APIs when we're done, the reason we do at the minute is that the clock API isn't available as standard.
