The commit 5725bce709db ("ASoC: simple-card-utils: Unify clock direction by clk_direction") corrupts the audio on STM32MP15 DK sound cards. The parent clock is not correctly set, because set_sai_ck_rate() is not executed in stm32_sai_set_sysclk() callback. This occurs because set_sysclk() is called with the wrong direction, SND_SOC_CLOCK_IN instead of SND_SOC_CLOCK_OUT. Add system-clock-direction-out property in SAI2A endpoint node of STM32MP15XX-DKX device tree, to specify the MCLK clock direction.
