Did it occure to anybody to look at these two patches for a second
before writing long essays about that's right and not? Because Patch
"one" is incomplete and the second patch is clearly doing a "FIXUP"
for the first. That's why they should be squashed. I do think, you'll
be just ignored if you try to post these as-is with your signed-off
on the linux-msm-arm. But then, why not give it a shot, this would
make for some good laughs if it went through as-is.
But from what I noticed, nobody did any of the requested perf
testing. These are absolutely necessary because the switch
from kpss-v1 to kpss-v2 clearly did have an big impact on the
performance. So let's not break anything because of a possible
incomplete patch (that might or might not require "ROM" support
that might or might not be present on all devices).

The other aspect of this is that you can also "offload" some of the blame
with retaining the original authorship if the patch goes sour. Because as
you have seen even the benight 32KHz (32000Hz vs 32768Hz) non-issue
(since it gets "rounded down" by the qcom-clk to 32000 see kernel debug)
can be a hot topic with conflicting "facts". Simply because we don't know
how the clock count is attained. If it's an external osc then it's probably
the "round" 32768 Hz, but if this sleep clock is generated from the 48 MHz
Osc reference (which we know is there, because these osc are big enough to
be spotted by looking at the PCB) then a "odd" 32000Hz is possible.
(That said, the highres timer fix seems to be definitely a winner.
I'm glad that you spotted it).
