I saw that you've created a new version of the patch and it was added to
different staging/testing [1] trees.

But I find it rather odd that Codeaurora uses different settings [3]. Here for 
easier comparison:

setting     | QSDK 1.1.3     | proposed patch
---------------------------------------------
clk-latency |         100000 |    256000
opp0        |     48000(000) |  48000000
opp1        |    200000(000) | 200000000
opp2        |    500000(000) | 500000000
opp3        |    710000(000) | 666000000

It looks to me like clk-latency and the opp3 (maximum frequency) are 
different. Is the reason for this difference known?

I've just noticed it because I got an DTB from an ODM which had even
716000(000) set for opp3.

Kind regards,
	Sven
