Hello, I want to add some Invensens Digital microphones via I2S interface and saw the kernel driver code* ics43432.c [1] *which could work, since no hw-parameters need to be set, only bitclock an LR-Clock needed.
I did not find any overlay to or device tree files to add or activate. So may questions: - has anybody done this and how, maybe an written an devicetree overlay ? - If not, I guess I have to write an overlay myself. Is there something other to do, since there is no ics43432 kernel modul * ?* - How to start writing a new overlay for the mcasp and codec and maybe add an codec kernel source myself for an array ? Is it wise to start from ctag-face-2-4 like like am335x-boneblack-ctag-face.dts (not an overlay) or any other overlay only using I2S input. Any hints are appreciated. Thanks !
