The iMX-TLV320AIC23 driver isn't from Freescale, but from a company named Eukrea Electromatique, originally for their own boards. From the code I get the impression it is a bit older, its DT options use a differing naming scheme. Patch it up a bit:
- Remove Eukrea naming, i.MX is from Freescale, TLV320AIC23 is from TI, driver was written by Eukrea, but it's DT capable, so it's not exclusive: - Kconfig option title - 'model' option - driver 'compatible' string - Other options just have changed over time, this driver remaining (one of) the last with the old semantics: - 'audio-codec' option (also moved from ssi node) - 'mux-int/ext-port' options - All options stay backwards compatible, the DT binding documents new and old names.
CONFIG variable and files have not been renamed, though, so no need to change old defconfigs.
