Core Clk Tree shows incorrect Clk rates at OPP50, as
in commit e07f469d284ca3d1f5dcf5438c22982be98bc071
calling of 'recalc' in API clk_set_rate is unintentionally
removed, because of which clock's tree rates get goofed
up when DVFS happens. This Patch adds recalc API back.
Tested on OMAP3630 SDP Board.

I see that the patch is not adding API back.
It is adding a call to the API.

That's intentional. struct clk.set_rate functions need to set the struct
clk.rate before returning. If they don't do that, it's a bug in the
struct clk's .set_rate function.

Clearly this isn't on the mainline kernel...

Yes, but in current code clk_set_rate of dpll3_m2 -
'omap3_core_dpll_m2_set_rate'
doesn't update clk.rate, I will submit patch fixing that bug and will
make sure that
set_rate of all clocks should update clk.rate

If you check for OPP50, the core clocks would show wrong rates.

Yes, that's the right thing to do, please send that. Such a patch was
originally part of the series for the last merge window; it seems I
inadvertently dropped it.

Ping. Do you plan to post this soon? This should be a trivial patch.

Hi Shweta ,
To avoid delay, yesterday posted a patch for the same with your signed
off by :
http://www.spinics.net/lists/linux-omap/msg50776.html
Please verify the patch and if anything is missing, please submit a new
patch.

Thanks Avinash for posting the Patch on time.
I have checked all clk's set_rate, other than 'omap3_dpll3_m2_set_rate'
all set_rate APIs update clk rate, so the patch is complete.
Acked.
