Does latest soc-core.c provide debugfs interface for peeking individual register? If not, I plan to add this interface.
codec_reg. This is the sort of question that can easily be answered by looking at the code, or a running system.
I checked soc-core.c on Linux next and I do not believe there is such debugfs interface. Here is the interface proposal.
By default, cat codec_reg prints entire register dump If someone echo "<register_addr>" > codec_reg before running cat codec_reg, only register address and value of given register would be printed. Afterward, state gets reset. Entire register dump gets printed if user cat codec_reg again
Please let me know if the proposal is not appropriate. Otherwise, I will start implementation going by proposed interface.
Thanks Patrick
