Thank you -- that coverage is worth a lot, but hold off a little, because the shape is changing again. Shawn Lin has asked for a DT property for the PERST# pulse rather than a decision taken in the driver, matching rockchip,perst-inactive-ms and rockchip,s2r-perst-inactive-ms in the vendor dwc driver, and I have agreed. So the version to test is that one, not the probe-only patch I was about to send. Whether the default changes or stays at PCIE_T_PVPERL_MS is still open, so I will put the DT snippet to set on a Helios64 in the cover letter instead of leaving it to guesswork.
