This node is 3c40000 and the one above is 3da0000. 3c comes before 3d.

But, won't that reduce readability and make things prone to error? If
the other patch doesn't get picked up soon, we should try this option.
We like to get this patch merged in v5.15.

Yeah, I messed up the order at a couple of places. Will fix.

The numbers are not supposed to change so maybe it reduces readability
but I don't see how it is prone to error.

The clk binding is already picked up but Bjorn would need to merge it
into the qcom tree to use it. I don't know what the plan is there.

I cross check GPU's clock list whenever there is a system level issue
like NoC errors. So it is convenient to have the clock names here, at
least for me. But, I will budge if it is not easy to manage the dependency.
