We are developing with IMX8mm.
In our custom board, We will use TDM audio codec(we replace WM8524 to custom FPGA).
so, I should replace audio driver. But I cannot find the source codes.
(I'm looking in the "4.14.78-r0 / git /" folder, but there are many source codes.)
What code do I need to modify to create and modify an audio driver for linux?
