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
