Re: [PATCH] phy: rockchip: naneng-combphy: Always configure SSC spread direction

Hi Alexey,

Thanks for pointing this out. You're right: my change duplicated the helper
logic, while your patch addresses the root cause. I tested your common fix on
a Linux 7.2-rc1-based kernel, in place of my RK3576-specific five-line change,
on an LCKFB Taishan Pi 3M with a HIKSEMI MD202 (0bda:9210, RTL9210-based)
connected to the USB3 Type-A port.

With your patch alone, the MD202 enumerated at 5 Gbit/s and completed a
64 MiB random write, sync, cache drop and SHA-256 readback. A 1 GiB raw
direct read also completed. Enumeration still worked after an ordinary
reboot and after hot unplug/replug, with no SuperSpeed reset, setup timeout,
error -71 or block I/O error during these tests.

The separate destructive 1 GiB filesystem write/hash stress that previously
exposed later RTL9210 enclosure instability was not repeated, so this result
does not claim that sustained-write issue is fixed.

Your patch fixes the reported use case and supersedes my RK3576-specific
patch.
