Dear all,

please correct me if I am wrong. Since the codec drivers have been converted to direct regmap API usage, it is not common to set the following snd_soc_codec_driver struct members:

.reg_cache_size .reg_word_size

However, the functions soc_codec_reg_show() and format_register_str() (responsible for formating and printing the codec register dumps to debugfs) depend on these members.

I'm writing a ASoC machine driver. The board has two wm8741 codecs. I would like to see the codec register dumps in debugfs.

eg: cat /sys/kernel/debug/asoc/<card_name>/codec:wm8741.1-001a/codec_reg cat /sys/kernel/debug/asoc/<card_name>/codec:wm8741.1-001b/codec_reg

Is it OK to set the above mentioned members in a codec driver to "enable" the register dump output? Or should we refactor the above mentioned functions to use the regmap API? Or am I missing something?

Thanks, Sergej
