I am not clear on what you mean. Please be more specific here.

I am not a big fan of this when you have the "device" around. You should just do
iommu_pclk = clk_get(&pdev->dev, NULL);
...error logic...
iommu_clk = clk_get(&pdev->dev, "iommu_clk");
...error logic...
The pclk is a "special" bus clock and does not have a specific device
instance associated with it, so passing a device would not be
appropriate in this case. I pass the device for other clocks that are
indeed associated with devices, but this is not one of them. I suppose
we could create 11 or 12 aliases for the pclk and associate it with all
the IOMMU devices, but I would prefer to avoid doing that as I believe
the current approach is cleaner.

Ok
