Subject: Re: [PATCH] msm: Remove arch-specific gpiomux tables
Hi Dima,
Thanks for your feedback. What you mention is absolutely right, and
accommodating that requires an architectural change which we have ready
and I will be pushing that out anytime.
This patch addresses your comments for removing the separate gpiomux
config file. My next patch series should provide you a complete picture.
Thanks,
Rohit
