The STM32 I2S drivers use Common Clock Framework thus they cannot be
built on platforms without it (e.g. compile test on MIPS with RALINK and
SOC_RT305X):

    /usr/bin/mips-linux-gnu-ld: sound/soc/stm/stm32_i2s.o: in function `stm32_i2s_hw_params':
    stm32_i2s.c:(.text+0x1870): undefined reference to `clk_set_parent'
