Re: [PATCH v2 2/4] ARM: OMAP2+: hwmod: add omap_hwmod_get_main_clk() API

Hi Tarun,

Thanks for this series, it will help us cleaning a little bit more the legacy stuff we have inside our data files.

Add an API to get main clock name associated with a given @oh.
This will avoid the need to construct fclk names during early
