2019-04-10ASoC: stm32: sai: fix master clock managementOlivier Moysan1-17/+47
When master clock is used, master clock rate is set exclusively. Parent clocks of master clock cannot be changed after a call to clk_set_rate_exclusive(). So the parent clock of SAI kernel clock must be set before. Ensure also that exclusive rate operations are balanced in STM32 SAI driver.

The new stm32_adfsdm driver has incomplete dependencies as shown by Kconfig: warning: (SND_SOC_STM32_DFSDM && LMP91000) selects IIO_BUFFER_CB which has unmet direct dependencies (IIO && IIO_BUFFER) sound/soc/stm/stm32_adfsdm.o: In function `stm32_adfsdm_trigger': stm32_adfsdm.c:(.text+0x8c): undefined reference to `stm32_dfsdm_get_buff_cb' stm32_adfsdm.c:(.text+0x9c): undefined reference to `stm32_dfsdm_release_buff_cb' This makes the dependency on SND_SOC_STM32_DFSDM unconditional, so we can always resolve the stm32_dfsdm_get_buff_cb/stm32_dfsdm_release_buff_cb symbols and get the implied IIO_BUFFER dependency. compile-testing on other platforms is still possible as long as that IIO driver is there.
