+
+description:
+ This binding describes the camera subsystem hardware found on Kaanapali
+ Qualcomm SoCs. It includes submodules such as CSIPHY (CSI Physical layer)
+ and CSID (CSI Decoder), which comply with the MIPI CSI2 protocol.
+
+ The subsystem also integrates a set of real-time image processing engines
+ and their associated configuration modules, as well as non-real-time engines.
+
+ Additionally, it encompasses a test pattern generator (TPG) submodule.

Pointed out by Krzysztof in the 8750 patches but the name of this clock
is gcc_axi_hf.

Please resolve the other inconsitencies pointed out by Krzysztof in that
thread here also.
I will have to skip application of this series in the meantime.

Hi Dmitry, this is MMNOC side of the AXI bus clock for the HF clients. If it's ok, we can change it to be consistent with previous generations for KNP and we can take it up in detail when we refactor the bindings for Hawi? Please let me know if you have a strong opinion on this at this point and we can discuss accordingly. Hi Bryan, we are addressing the things that makes sense for KNP as well in the next revision. Btw, couple things like a separate CSIPHY DT node and ordering of the resources (that were to be added at the end as you advised), I believe are not relevant for KNP. As for the GDSC names, we preferred the module name and it's GDSC name to be consistent so changed the latter as well to VFE. Hope that's ok. Please let us know if you would suggest any further changes to KNP v9 bindings and we can move forward accordingly. Thank you both. >> Please resolve the other inconsitencies pointed out by Krzysztof in that >> thread here also. >> >> I will have to skip application of this series in the meantime. >> >> --- >> bod

I think its reasonable to omit the CSIPHY split but the other things - clock names, namespace consistency with previous version should be maintained. --- bod

Well, why do you think that for Hawi the requirement will be different? It's the same: describe the _use_ of the clock rather than the source. You got that feedback internally already during our telcos and then later when you've sent your proposal, but for some reason you didn't get it. BTW, if it's an MMNOC end of the bus, should it instead be voted by the NoC driver? > Hi Bryan, we are addressing the things that makes sense for KNP as well in > the next revision.
