[PATCH v15 03/15] accel/rocket: wait for a running IRQ handler before resetting a core

[Jiaxing Hu]

Hi Heiko,

On 3/15 you're right. With synchronize_irq() added, the original comment
already describes what happens, so v16 no longer changes it.

In 4/15 the code no longer uses pm_runtime_put_noidle(), so only the last
part of that comment changes to match.

I've shortened the commit messages of 3/15 and 1/15 in v16. 1/15 is
Igor's patch, so the change is marked in its tag block; Igor, say if you'd
rather keep your text.

On the power domains in 14/15: I tested each core with only its own power
domain. With both cores running the results are correct, so v16 uses one
power domain per core and drops the driver code that handled more than
one.

On the IOMMU clocks in 8/15: I tested different combinations. With only
aclk and iface the IOMMU reset fails, and without either one of the CBUF
clocks it does not work either. With all four clocks it works, and the
npu clock is not needed, so v16 lists four.

Thanks,
Jiaxing
