The 200 ms delay before debouncing the PHY in `sata_link_resume()` is
not needed for the Marvell 88SE9235.
$ lspci -nn -s 0021:0e:00.0

So, remove it. Tested on IBM S822LC with current Linux 5.17-rc1:

Looks good. But for the commit message, instead of the dmesg copy-paste,
could you simply write the gains in terms of shortened scan time ? That
would make it easier to understand the benefits of the patch. Also,
there is no need for the lspci output.

I can do:

I would still like to keep the Linux logs, as then it’s clear what I
tested with (drives), and what ports were populated.
> Also, there is no need for the lspci output.
In my opinion, it prooves I used the correct PCI vendor and device
codes, and also shows the revision number of the device I tested with.
Kind regards,

OK. Keep the dmesg log if you want, but add the summary. Something like:
Without this patch (with 200 ms delay): device probe takes X ms
<dmesg>
With patch (no delay): device probe takes Y ms
<dmesg>

* [PATCH] ata: ahci: Skip 200 ms debounce delay for Marvell 88SE9235

To: Damien Le Moal; +Cc: Paul Menzel, linux-ide, linux-kernel
The 200 ms delay before debouncing the PHY in `sata_link_resume()` is
not needed for the Marvell 88SE9235.
$ lspci -nn -s 0021:0e:00.0
0021:0e:00.0 SATA controller [0106]: Marvell Technology Group Ltd. 88SE9235 PCIe 2.0 x2 4-port SATA 6 Gb/s Controller [1b4b:9235] (rev 11)
So, remove it. Tested on IBM S822LC with current Linux 5.17-rc1:
Currently, without this patch (with 200 ms delay), device probe for ata1
takes 485 ms:
[ 3.358158] ata1: SATA max UDMA/133 abar m2048@0x3fe881000000 port 0x3fe881000100 irq 39

With this patch (no delay) device probe for ata1 takes 273 ms:
