sof-hda-dsp: don't fail if Auto-Mute control is not present
by GitHub pull_request - opened 10 Jun '20

10 Jun '20

alsa-project/alsa-ucm-conf pull request #33 was opened from kv2019i: The "Auto-Mute Mode" control is not present in all HDA codecs. The generic SOF HDA UCM file should be robust enough to handle these cases as well.

So removing reference to slimbus_bus is necessary in this case. On the other hand, SLIMBus is going to be used sm8250 for BT audio, so this would not be unnecessary. Also mostly these are build as modules, so not sure why kernel size will increase here! Am not 100% sure if SLIMBus will be kept on all SoCs, but keeping depends or imply in place would enforce or spell out some level of dependency on this. > >>> help >>> SoundWire Qualcomm Master driver. >>> diff --git a/drivers/soundwire/qcom.c b/drivers/soundwire/qcom.c >>> index 14334442615f..ac81c64768ea 100644 >>> --- a/drivers/soundwire/qcom.c >>> +++ b/drivers/soundwire/qcom.c >>> @@ -769,13 +769,18 @@ static int qcom_swrm_probe(struct >>> platform_device *pdev) >>> if (!ctrl) >>> return -ENOMEM; >>> +#ifdef CONFIG_SLIMBUS >>> if (dev->parent->bus == &slimbus_bus) { >>> +#else >>> + if (false) { >>> +#endif >> >> May be you can do bit more cleanup here, which could endup like: >> >> >> ctrl->regmap = dev_get_regmap(dev->parent, NULL); >> if (!ctrl->regmap) { >> res = platform_get_resource(pdev, IORESOURCE_MEM, 0); >> if (res) { >> ctrl->mmio = devm_ioremap_resource(dev, res); >> if (IS_ERR(ctrl->mmio)) { >> dev_err(dev, "No valid mem resource found\n"); >> return PTR_ERR(ctrl->mmio); >> } >> >> ctrl->reg_read = qcom_swrm_cpu_reg_read; >> ctrl->reg_write = qcom_swrm_cpu_reg_write; >> } else { >> dev_err(dev, "No valid slim resource found\n"); >> return -EINVAL; >> } >> } else { >> ctrl->reg_read = qcom_swrm_ahb_reg_read; >> ctrl->reg_write = qcom_swrm_ahb_reg_write; >> } >> >> >> >> thanks, >> srini > > I don't think this is better, it feels more obfuscated, and I think its > possible we may end up with the mmio sdw having a parent with a regmap. > (it is not how I did things up in my upstream stack, but in downstream > the sdw nodes are inside the "macro" codec nodes) > > I understand the '#ifdef CONFIG_SLIMBUS'/'dev->parent->bus == > &slimbus_bus' is ugly, but at least its clear what's going on.

Things like alsactl definitely do, and obviously anything that starts after the firmware loads will be fine too.
