Why no IRIS_HW_AHB_CLK in power on sequence?

So if you rewrite the code that you have list of clocks for hw power on
(IRIS_HW_CLK + IRIS_HW_AHB_CLK for all variants, +IRIS_BSE_HW_CLK on
this variant) you could have just one function for all of them and
devices will be fully compatible.

No?

The original patch was to add the IRIS_BSE_HW_CLK operation into the
common API, but Dmitry requested to separate Purwa's implementation out
independently.

So you don't know why you are doing things? I don't understand what sort
of argument is that.

You are duplicating code, while all this is simply the same logic -
three clocks which need to be enabled.

Best regards,
Krzysztof

Hi Dmitry,

I think this can be moved into the common code, so that any future VPU3-related changes will also be applied to purwa. What do you think? If that works, I’ll update it in the next version.
