Subject: Re: [PATCH 1/5] MFD,mmc: tmio_mmc: make HCLK configurable


Acked-by: Ian Molton <spyro@....com>

However I'd like to see the clk API  weaned of its CPU spcific 
dependencies so that it can be used for this purpose instead.

I consider ASIC3 support in this driver more important and this change 
is pretty noninvasive. Converting to the clk api in future shouldnt be 
any harder with this patch (actually slightly easier).
