This takes some of the work done to auto-configure quirks/routing for ESS83xx codecs by getting the info from ACPI from: https://github.com/thesofproject/linux/pull/4112
And then builds on top of this to add auto-configuration to the bytcht_es8316 board driver.
Sounds good, thanks for doing this Hans! I only have two minor questions, see below.
Note compared to the pull-request, which deals with the ES8336, this series deals with the ES8316 (for which I have several devices to test on) and this moves all handling from the codec driver to the board driver where this IMHO belongs.
The ACPI stuff is in theory not Intel-specific, so not sure why it would belong in sound/soc/intel/boards? I initially put the code in sound/soc/codecs since the _DSM method is in the scope of the codec device HID.
After this series audio now works properly on a CHT Chuwi Hi12 tablet without needing to add an extra quirk for that model.
This has also been tested on the following devices, where things are unchanged from before (the ACPI autoconfiguration gives the same results as the old defaults) :
Onda V80 plus (CHT) GP-electronic T701 (BYT)
I also tested this on a Nanote UMPC-01, here the _DSM result for PLATFORM_SPK_TYPE_ARG wrongly returns 1 (mono) while the device actually has 2 speakers, so this model needs to keep its DMI quirk.
What about the two others?
/* Irbis NB41 */ /* Teclast X98 Plus II */
Are they part of your set of devices and could the quirks be removed?
