I am not sure which one is better? Best regards wang shengjiu

[1/1] ASoC: imx-rpmsg: Support configure sysclk for codec dai commit: 088f115c6ff664c8afe003bd542e1e662a72aaed All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark

Some codecs need to configure the sysclk even with slave mode, otherwise it may not work properly with some case. wm8960 is the one that need sysclk be configured, so add late_probe() to call the snd_soc_dai_set_sysclk() of codec Signed-off-by: Shengjiu Wang <shengjiu.wang@nxp.com> --- sound/soc/fsl/imx-rpmsg.c | 29 +++++++++++++++++++++++++++++ 1 file changed, 29 insertions(+)
