According to the datasheet: R16528 (4090h) Clock Control1 BIT 0: CLKOUT output source select 0 = FLL output 1 = 32.768kHz oscillator Thus fix the entry order in wm831x_clkout_parents[] to make it has the same meaning as the datasheet and make the return value of wm831x_clkout_get_parent() consistent with the parent pass to wm831x_clkout_set_parent().
