Subject: Re: [PATCH] ARM: mmp/brownstone: add regulator init data for max8925
Haojian,
For the ldos may supply for multiple devices on brownstone board,
so it can not simply match the dev_name and devices.
Pls ignore this patch, we can later add the driver and at that time
we can add the max8925's regulator init data case by case.
Thx,
Leo Yan
