Re: [PATCH] msm: Remove arch-specific gpiomux tables

From: Rohit Vaswani

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

I don't like this solution of putting the magicly named array into the
board file. What if I want multiple boards to be built into the same
kernel? What if I want multiple tables in case I have different
revisions of the board?

The more correct way would be to add a function to gpiomux.c to be
able to apply a list of gpiomux configs, something like:

int msm_gpiomux_config_table(struct msm_gpiomux_cfg *table, int num);

The gpiomux configs are board-specific and thus should be
a part of the board file.
