[1/1] ASoC: simple-card-utils: Unify clock direction by clk_direction commit: 5725bce709db1c001140d79398581e067e28c031 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

Original sample-card assumes SND_SOC_CLOCK_IN is used for snd_soc_dai_set_sysclk(), but someday, Codec uses SND_SOC_CLOCK_IN and CPU uses SND_SOC_CLOCK_OUT at hw_params(), and dai->clk_direction is used at simple_init_dai(). There is no uniformity today. Let's use dai->clk_direction for all cases. Fortunately, almost all DAI doesn't care about "dir" (= SND_SOC_CLOCK_IN/OUT) in .set_sysclk callback function (which is called in snd_soc_dai_set_sysclk()), so this patch has no effect in such DAIs. But this patch might breaks some existing Sound Card. Use "system-clock-direction-out" property if it needs to use SND_SOC_CLOCK_OUT Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> --- sound/soc/generic/simple-card-utils.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-)
