Cover letter [PATCH 0/3] cpufreq: dt: Allow platforms to provide suspend/resume hooks
Hi Viresh,

Hi Miquel,
This is in response to the patch[1] you sent.
Thank you very much for taking the time to look into it.

I have updated the cpufreq-dt driver to allow platform specific suspend/resume hooks and done some minor cleanup in the driver. I have updated your patch and applied that on top of all this. I haven't tested any of this and would need your help to get that done.
I tested on an EspressoBin (Armada 3720), it works.
However, I first had a panic due to the clock being 'put' twice. I suggest you to merge this [1] into the second patch. With this (or something similar):
And the path error was reached because I did not select the cpufreq-dt driver in menuconfig, which I think should be selected by default when enabling the armada37xx-cpufreq driver. I wrote a small patch for that too, see [2]. Tell me if you want me to send it of if you want to include it in the next version ?
