LKFT test reported regression on TI BeagleBoard-X15 arm32 bit platform as
The device was not able to detect SATA drive.

dmesg short log:

ata1: SATA link down (SStatus 0 SControl 300)

    ARM: OMAP2+: Drop legacy platform data for dra7 sata

    We can now probe devices with ti-sysc interconnect driver and dts data.
    Let's drop the related platform data and custom ti,hwmods dts property.

    As we're just dropping data, and the early platform data init is based on
    the custom ti,hwmods property, we want to drop both the platform data and
    ti,hwmods property in a single patch.

Thanks for the report, looks like we are now missing the sata related
quirk flags compared to the patch above.

Below is a quick patch to add the missing quirk flags that might help
if you can give it a try.

Regards,

Tony

Great to see that this is about to be fixed. And Naresh, many thx for
giving the #regzb tag a try, even if regzbot (shameless plug for the
unaware: https://linux-regtracking.leemhuis.info/post/regzbot-approach/
) is not up and running already, much appreciated!

But FWIW, you don't need to add the tag to the subject; in fact, better
use it for it's intended purpose. Instead add the tag to the mail's
body, like this:

#regzb introduced: 98feab31ac49 ("ARM: OMAP2+: Drop legacy platform data
for dra7 sata")

Just ensure there is a blank line after that, as regzbot will have to
deal with line breaks (as can be seen above) and somehow needs to decide
where to stop. ;-)

Ohh, and Tony, if you want to do me a favour please include

Link:
https://lore.kernel.org/regressions/CA+G9fYtTN6ug3eBAW3wMcDeESUo+ebj7L5HBe5_fj4uqDExFQg@mail.gmail.com/

in the commit message of the fix, then I have some real data already at
hand to test regzbot in practice. :-D

Ciao, Thorsten

OK sent with a fixes and link tag. As a test, I sent it to the lists I
usually send patches to for this driver. The subject line is different,
and I left out all the extra Cc including you and regzb mailing list as
those are easy to forget to add to the mail. Let's see if regzb finds
the fix based on the Link or Fixes tag :)

Tony

The code is still very early WIP, so not yet published, but I'll publish
the first few bits in a week or two, even if they are not yet useful to
anyone besides myself. ;-)
