After probe, the power may be disabled, so move mark_dirtry to runtime_resume, then regcache can re-write all the registers. best regards wang shengjiu > > > > + regcache_sync(asrc->regmap); > > + > > + regmap_update_bits(asrc->regmap, REG_ASRCFG, > > + ASRCFG_NDPRi_ALL_MASK | ASRCFG_POSTMODi_ALL_MASK | > > + ASRCFG_PREMODi_ALL_MASK, asrc_priv->regcache_cfg); > > + > > + /* Restart enabled pairs */ > > + regmap_update_bits(asrc->regmap, REG_ASRCTR, > > + ASRCTR_ASRCEi_ALL_MASK, asrctr); > > + > > return 0; > > > > disable_asrck_clk: > > @@ -1155,6 +1175,11 @@ static int fsl_asrc_runtime_suspend(struct device *dev) > > struct fsl_asrc_priv *asrc_priv = asrc->private; > > int i; > > > > + regmap_read(asrc->regmap, REG_ASRCFG, > > + &asrc_priv->regcache_cfg); > > + > > + regcache_cache_only(asrc->regmap, true); > > + > > for (i = 0; i < ASRC_CLK_MAX_NUM; i++) > > clk_disable_unprepare(asrc_priv->asrck_clk[i]); > > if (!IS_ERR(asrc->spba_clk)) > > @@ -1166,51 +1191,10 @@ static int fsl_asrc_runtime_suspend(struct device *dev) > > } > > #endif /* CONFIG_PM */ > > > > -#ifdef CONFIG_PM_SLEEP > > -static int fsl_asrc_suspend(struct device *dev) > > -{ > > - struct fsl_asrc *asrc = dev_get_drvdata(dev); > > - struct fsl_asrc_priv *asrc_priv = asrc->private; > > - > > - regmap_read(asrc->regmap, REG_ASRCFG, > > - &asrc_priv->regcache_cfg); > > - > > - regcache_cache_only(asrc->regmap, true); > > - regcache_mark_dirty(asrc->regmap); > > - > > - return 0; > > -} > > - > > -static int fsl_asrc_resume(struct device *dev) > > -{ > > - struct fsl_asrc *asrc = dev_get_drvdata(dev); > > - struct fsl_asrc_priv *asrc_priv = asrc->private; > > - u32 asrctr; > > - > > - /* Stop all pairs provisionally */ > > - regmap_read(asrc->regmap, REG_ASRCTR, &asrctr); > > - regmap_update_bits(asrc->regmap, REG_ASRCTR, > > - ASRCTR_ASRCEi_ALL_MASK, 0); > > - > > - /* Restore all registers */ > > - regcache_cache_only(asrc->regmap, false); > > - regcache_sync(asrc->regmap); > > - > > - regmap_update_bits(asrc->regmap, REG_ASRCFG, > > - ASRCFG_NDPRi_ALL_MASK | ASRCFG_POSTMODi_ALL_MASK | > > - ASRCFG_PREMODi_ALL_MASK, asrc_priv->regcache_cfg); > > - > > - /* Restart enabled pairs */ > > - regmap_update_bits(asrc->regmap, REG_ASRCTR, > > - ASRCTR_ASRCEi_ALL_MASK, asrctr); > > - > > - return 0; > > -} > > -#endif /* CONFIG_PM_SLEEP */ > > - > > static const struct dev_pm_ops fsl_asrc_pm = { > > SET_RUNTIME_PM_OPS(fsl_asrc_runtime_suspend, fsl_asrc_runtime_resume, NULL) > > - SET_SYSTEM_SLEEP_PM_OPS(fsl_asrc_suspend, fsl_asrc_resume) > > + SET_SYSTEM_SLEEP_PM_OPS(pm_runtime_force_suspend, > > + pm_runtime_force_resume) > > }; > > > > static const struct fsl_asrc_soc_data fsl_asrc_imx35_data = { > > -- > > 2.21.0 > >

I see. Just noticed that you add a regcache_cache_only in probe(). Acked already. Thanks.

Applied to https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next Thanks! [1/1] ASoC: fsl_asrc: Merge suspend/resume function to runtime_suspend/resume commit: 393dc21d0f25e8fcde8baca78b8a38afe61db2a7 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

With dedicated power domain for asrc, power can be disabled after probe and pm runtime suspend, then the value of all registers need to be restored in pm runtime resume. So we can merge suspend/resume function to runtime_suspend/resume function and enable regcache only in end of probe.
