non-krait ones have clock source selections inside apcs, on krait ones its not there
<aka_[m]>
you need to check which driver 8226 uses for cpu-clk
<aka_[m]>
but i believe its same like 8916
<aka_[m]>
mal: if i were you i would try either adding new compatible(or preferable) switch to already existing one.
<aka_[m]>
I can risk saying you can use 8916 compatible
<aka_[m]>
then add A53 pll same way like its on 8916
<aka_[m]>
and you should have freq scalling working
<aka_[m]>
definitions for a7pll on such old platform are inside gcc and looks to use sr2 ops

konradybcio: thanks.
<aka_[m]>
konradybcio: can intf clock be optional somehow?
<aka_[m]>
on 8940 which is 8937+IPA we would need to handle IPA RPM clock
<konradybcio>
generally there is no thing as an optional clock
<aka_[m]>
otherwise every node is same
<konradybcio>
it's either enabled (may be by somebody else that you aren't aware of) or not (which will result in an access fault and your board will die)
<aka_[m]>
probe is inside icc-smd/rpm so i guess i cannot override it
<aka_[m]>
or make matchtable in it
<aka_[m]>
hmm
<aka_[m]>
what if i make like third od_device_id
<aka_[m]>
and have like "qcom,msm8940-XXXXX"
<aka_[m]>
wouldn't it be weird to have snoc,snoc-mm,bimc using 8937 compatible and pcnoc alone with 8940 in dts?
<konradybcio>
i think the ipa clock shouldn't be reachable on platforms without it
<aka_[m]>
thats not exactly what will be but some kind of idea
<aka_[m]>
konradybcio: so request would fall
<konradybcio>
either fail or reboot the device
<aka_[m]>
and fail to load bus
<aka_[m]>
but on 8940 there is ipa
<aka_[m]>
so it needs it
<konradybcio>
you can basically tell by adding it in clk-smd-rpm and seeing if the device still boots
<aka_[m]>
I guess additional compatible in of_device_id would work
<aka_[m]>
But need someone to rest
<aka_[m]>

mal: without looking at the current binding, you could make sure that there's both 8974-kpss and 8226-non-kpss compatibles in there...
<bamse>
mal: but i'd also accept a patch just ignoring the difference...

I haven't really check yet, is there cpr on cpufreq-hw socs? Or is there it but it's being handled fully by firmware?
<lumag>
aka_[m], even if there is one, it is handled by the firmware
