But I find it rather odd that Codeaurora uses different settings [3]. Here = for=20 easier comparison: setting | QSDK 1.1.3 | proposed patch =2D-------------------------------------------- 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=20 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.
