The wm8960 driver supports an automatic clocking mode which will use the MCLK directly where possible and fall back to the PLL if there is no suitable configuration directly using the MCLK. Clock 0 will be used by the generic cards when configuring things, currently this is a MCLK only mode but using AUTO mode would be more functional. Since the driver still prefers to use MCLK directly where possible there should be no negative impact on systems which are able to use MCLK directly. As far as I can see nothing is using the system clock as part of the ABI, the only reference I can see to a mode in a machine driver is the Freescale i.MX card which uses the automatic mode with an explicit in kernel call using the constant so will be unaffected.
