Kconfig	ASoC: stm: depend on COMMON_CLK to fix compile tests 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' Reported-by: kernel test robot <lkp@intel.com> Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Link: https://lore.kernel.org/r/20201116175133.402553-3-krzk@kernel.org Signed-off-by: Mark Brown <broonie@kernel.org>	5 年前

stm32_sai.c	ASoC: stm32: sai: fix OF node leak on probe commit 23261f0de09427367e99f39f588e31e2856a690e upstream. The reference taken to the sync provider OF node when probing the platform device is currently only dropped if the set_sync() callback fails during DAI probe. Make sure to drop the reference on platform probe failures (e.g. probe deferral) and on driver unbind. This also avoids a potential use-after-free in case the DAI is ever reprobed without first rebinding the platform driver.

stm32_sai_sub.c	ASoC: stm32_sai: fix incorrect BCLK polarity for DSP_A/B, LEFT_J [ Upstream commit 0669631dbccd41cf3ca7aa70213fcd8bb41c4b38 ] The STM32 SAI driver do not set the clock strobing bit (CKSTR) for DSP_A, DSP_B and LEFT_J formats, causing data to be sampled on the wrong BCLK edge when SND_SOC_DAIFMT_NB_NF is used. Per ALSA convention, NB_NF requires sampling on the rising BCLK edge. The STM32MP25 SAI reference manual states that CKSTR=1 is required for signals received by the SAI to be sampled on the SCK rising edge. Without setting CKSTR=1, the SAI samples on the falling edge, violating the NB_NF convention. For comparison, the NXP FSL SAI driver correctly sets FSL_SAI_CR2_BCP for DSP_A, DSP_B and LEFT_J, consistent with its I2S handling. This patch adds SAI_XCR1_CKSTR for DSP_A, DSP_B and LEFT_J in stm32_sai_set_dai_fmt which was verified empirically with a cs47l35 codec. RIGHT_J (LSB) is not investigated and addressed by this patch. Note: the STM32 I2S driver (stm32_i2s_set_dai_fmt) may have the same issue for DSP_A mode, as I2S_CGFR_CKPOL is not set. This has not been verified and is left for a separate investigation.
