Subject: Re: [PATCH RESEND 1/5] mfd: arizona: Add registers for ADC microphone
detection
Hi Lee, Charles,
I make the temporary branch[1] and then apply patch1-patch4 without patch5
because of patch5 may need the ack message by DT maintainer. If Lee want to
make the immutable branch and send the pull request, I'll make the immutable
branch based on Linux-4.3-rcX and send it to MFD maintainer (Lee Jones).
[1] branch name : extcon-next-v4.4-for-arizona
- git.kernel.org/cgit/linux/kernel/git/chanwoo/extcon.git/log/?h=extcon-next-v4.4-for-arizona
I need the your opinion.
Thanks,
Chanwoo Choi
