On smdk boards(atleast on smdk5250 and smdk5420) there is no XCLKOUT
funda. Codec MCLK can get clock from oscillator clock in codec master
mode or i2scdclk in codec slave mode. XCLKOUT is there in some other
variants of 5250 and 5420 where it is using other codecs than wm8994.
But the mux and divider of XCLKOUT is out of CMU. As Sylwester told it
is there in PMU registers.
Thanks
Padma
