[PATCH] mfd: add tps65910 32-kHz-crystal-input init

From: Johan Hovold
Date: Wed Jul 11 2012 - 09:44:46 EST


Replace tps65910_misc_init with a dedicated init function for the
32-kHz-crystal input.

Hi Samuel,

How about something like this? My thought with misc_init was that it could be
extended should more simple initialisation like for the ck32k_xtal need to be
done, but perhaps it's cleaner to stick with dedicated init functions
through-out. At least for now.

Thanks,
Johan
