I'm not seeing anything here which prevents userspace coming in and change the configuration while we're in this function, that would obviously have serious issues. I'm also wondering if this might be more elegantly implemented by going into cache bypass mode, doing the test and then using a cache resync to restore the initial configuration.

In a system scenario the likelihood of that happening is small as you cannot use the mic or headphones until they've been inserted. The system is only likely to act after the jack insertion events have occurred. However, it would be better to prevent any chance of concurrent access. The problem is how best to lock the Kcontrols whilst the test procedure in progress. At the moment the only way I can see is to add explicit control set() functions which would use a lock that can also be controlled by the HP test code. Does this make sense to you or do you know of a simpler method? Obviously dapm has function to lock as required. For the cache resync idea, in terms of code, it will look cleaner, but you are talking about 4 to 5 times the number of I2C accesses to the device, to restore configuration. Does that not seem like a bit too much overhead? > > + if (statusa & DA7219_JACK_TYPE_STS_MASK) { > > + report |= SND_JACK_HEADSET; > > + mask |= SND_JACK_HEADSET | > SND_JACK_LINEOUT; > > + schedule_work(&da7219_aad->btn_det_work); > > + } else { > > + schedule_work(&da7219_aad->hptest_work); > > + } > > Why are we scheduling work - we're already in thread context? hptest will take some time to complete (over 100ms), and in that time it's plausible that a user could remove the jack. If we deal with this in the IRQ thread, we won't be aware of jack removal during the process, and will send a report regardless, which will almost definitely be incorrect, and unnecessary. By spawning off work, it allows the removal to be dealt with if the hptest work procedure is currently in process, and then we can avoid sending incorrect jack reports at the end. For button detection, for certain mics it's required to pulse the micbias to a higher voltage, for a defined period of time, to enable the mic. Again this period is likely to take maybe 100ms, depending on the mic, so it made far more sense to me to do this outside of the IRQ thread. However, if you have a better proposal for this then am happy to take it on board. > > + /* Un-drive headphones/lineout */ > > + snd_soc_update_bits(codec, DA7219_HP_R_CTRL, > > + DA7219_HP_R_AMP_OE_MASK, 0); > > + snd_soc_update_bits(codec, DA7219_HP_L_CTRL, > > + DA7219_HP_L_AMP_OE_MASK, 0); > > This looks like DAPM? The control of driving the headphones or making them high impedance is handled in the AAD code because we cannot have the headphones driven before a jack is inserted as it will affect the pole detection. Adding it to DAPM seemed like it would cause more problems in terms of controlling when it would and wouldn't be enabled. > > +static enum da7219_aad_jack_ins_deb da7219_aad_of_jack_ins_deb(u32 val) > > +{ > > + switch (val) { > > + case 5: > > + return DA7219_AAD_JACK_INS_DEB_5MS; > > + case 10: > > + return DA7219_AAD_JACK_INS_DEB_10MS; > > + case 20: > > + return DA7219_AAD_JACK_INS_DEB_20MS; > > + case 50: > > + return DA7219_AAD_JACK_INS_DEB_50MS; > > + case 100: > > + return DA7219_AAD_JACK_INS_DEB_100MS; > > + case 200: > > + return DA7219_AAD_JACK_INS_DEB_200MS; > > + case 500: > > + return DA7219_AAD_JACK_INS_DEB_500MS; > > + case 1000: > > + return DA7219_AAD_JACK_INS_DEB_1S; > > + default: > > + return DA7219_AAD_JACK_INS_DEB_20MS; > > This isn't an error?

The register defined for the Kcontrol is the first in the sequence of two registers (first lower byte, second upper byte).

In a system scenario the likelihood of that happening is small as you cannot use the mic or headphones until they've been inserted. The system is only likely to act after the jack insertion events have occurred. However, it would be better to prevent any chance of concurrent access. The problem is how best to lock the Kcontrols whilst the test procedure in progress. At the moment the only way I can see is to add explicit control set() functions which would use a lock that can also be controlled by the HP test code. Does this make sense to you or do you know of a simpler method? Obviously dapm has function to lock as required. For the cache resync idea, in terms of code, it will look cleaner, but you are talking about 4 to 5 times the number of I2C accesses to the device, to restore configuration. Does that not seem like a bit too much overhead? > > + if (statusa & DA7219_JACK_TYPE_STS_MASK) { > > + report |= SND_JACK_HEADSET; > > + mask |= SND_JACK_HEADSET | > SND_JACK_LINEOUT; > > + schedule_work(&da7219_aad->btn_det_work); > > + } else { > > + schedule_work(&da7219_aad->hptest_work); > > + } > > Why are we scheduling work - we're already in thread context? hptest will take some time to complete (over 100ms), and in that time it's plausible that a user could remove the jack. If we deal with this in the IRQ thread, we won't be aware of jack removal during the process, and will send a report regardless, which will almost definitely be incorrect, and unnecessary. By spawning off work, it allows the removal to be dealt with if the hptest work procedure is currently in process, and then we can avoid sending incorrect jack reports at the end. For button detection, for certain mics it's required to pulse the micbias to a higher voltage, for a defined period of time, to enable the mic. Again this period is likely to take maybe 100ms, depending on the mic, so it made far more sense to me to do this outside of the IRQ thread. However, if you have a better proposal for this then am happy to take it on board. > > + /* Un-drive headphones/lineout */ > > + snd_soc_update_bits(codec, DA7219_HP_R_CTRL, > > + DA7219_HP_R_AMP_OE_MASK, 0); > > + snd_soc_update_bits(codec, DA7219_HP_L_CTRL, > > + DA7219_HP_L_AMP_OE_MASK, 0); > > This looks like DAPM? The control of driving the headphones or making them high impedance is handled in the AAD code because we cannot have the headphones driven before a jack is inserted as it will affect the pole detection. Adding it to DAPM seemed like it would cause more problems in terms of controlling when it would and wouldn't be enabled. > > +static enum da7219_aad_jack_ins_deb da7219_aad_of_jack_ins_deb(u32 val) > > +{ > > + switch (val) { > > + case 5: > > + return DA7219_AAD_JACK_INS_DEB_5MS; > > + case 10: > > + return DA7219_AAD_JACK_INS_DEB_10MS; > > + case 20: > > + return DA7219_AAD_JACK_INS_DEB_20MS; > > + case 50: > > + return DA7219_AAD_JACK_INS_DEB_50MS; > > + case 100: > > + return DA7219_AAD_JACK_INS_DEB_100MS; > > + case 200: > > + return DA7219_AAD_JACK_INS_DEB_200MS; > > + case 500: > > + return DA7219_AAD_JACK_INS_DEB_500MS; > > + case 1000: > > + return DA7219_AAD_JACK_INS_DEB_1S; > > + default: > > + return DA7219_AAD_JACK_INS_DEB_20MS; > > This isn't an error?

Again some documentation would help, and also using raw reads rather than bulk reads (which imply that all endianness issues will be taken care of). If you're doing a bulk read and handling endianness that's worrying.

Is this now the common naming to be used for all future codecs? It's always been the naming in ControlNames.txt - we don't generally worry about it on devices with more flexible routing which mean that the associated meaning won't always be really true but for this device it seems that the options are sufficiently limited to allow userspace to use the standard name. > > > + /* Internal LDO */ > > > + if (da7219->use_int_ldo) > > > + snd_soc_update_bits(codec, DA7219_LDO_CTRL, > > > + DA7219_LDO_EN_MASK, > > > + DA7219_LDO_EN_MASK); > > If there is an option to use an external supply I would expect to see > > the regulator API used to discover the external LDO (and ideally also to > > configure the integrated LDO).

The point here isn't really the control of the LDO itself, it's making sure that the integration with external supplies works well - the key bit is that how we figure out that we don't have an external supply connected should be joined up with how we normally integrate external supplies. > > > + /* > > > + * There are multiple control bits for the input mixer. > > > + * The following can be enabled now as it's not power related. > > > + */ > > > + snd_soc_update_bits(codec, DA7219_MIXIN_L_CTRL, > > > + DA7219_MIXIN_L_MIX_EN_MASK, > > > + DA7219_MIXIN_L_MIX_EN_MASK); > > So the chip designers just put these in for randomness?

It seems likely to be more robust against someone realising that the register bits actually do something useful and need toggling and it raises less eyebrows code wise. If you're worried about the register writes you should also be able to arrange to map these in as mixer widgets which would mean that the the core will combine the writes with the main power controls.

Yes, there's a disable_pin() call for micbias. However that will not disable the pin indefinitely which is what I would require for this.

Given the way that the driver code was structured, and that the IRQ is only used for accessory detection, I added it to the child node. The other option would be to flatten out bindings, and remove the child node. Felt like keeping the accessory detect items separate though was a sensible approach.
