From: Andrew Jackson <redacted> Some I2S clocks may require some time to get the clock ready for operation and so need to be prepared before they are enabled. So, prepare the clock as well as enabling it, but combine the two through clk_prepare_enable.
More turkey-focussed issues: this should have a clk_disable_unprepare too. Sigh Andrew
