[PATCH] arm64: dts: rockchip: fix isp iommu clocks and power domain

[Helen Koike]

isp iommu requires wrapper variants of the clocks.
noc variants are always on and using the wrapper variants will activate
{A,H}CLK_ISP{0,1} due to the hierarchy.

Also add the respective power domain.

Refer:

Hello,

I tested this using the isp patch set (which is not upstream
yet). Without this patch, streaming from the isp stalls.

I'm also enabling the power domain and removing the disable status,
please let me know if this should be done in a separated patch.

Thanks
Helen

I think you might want to put the comments about enabling power domain
and removing disable status on the commit log. It's useful information :-)

Thanks,

Tested on Rock960 with ISP patches.

applied for 5.3 with the received Tested-tag and I also moved
parts of the comment into the commit message making it:

"isp iommu requires wrapper variants of the clocks.
noc variants are always on and using the wrapper variants will activate
{A,H}CLK_ISP{0,1} due to the hierarchy.

Tested using the pending isp patch set (which is not upstream
yet). Without this patch, streaming from the isp stalls.
    
Also add the respective power domain and remove the "disabled" status.
