Thanks. Has the Fix patch been merged ? Commit Id ?
Not yet. I'm planning to send it next week (after v5.13-rc1 is out) as a fix.
For your convenience the whole story is available in my publick branch:

https://gitlab.com/andy-shev/next/-/tree/topic/spi/reload

and yes, I have tested it on real hardware.
Oh what a nightmare you got into there.

Curious that ACPI has SPI CS as always active high,
but that just underscore that we *really* need to
abstract this out to avoid really complex specialcasing.

Interesting that the PXA2xx XScale lives in Merrifield,
I didn't know. Reminds med of how the Samsung
hardware is alive and well in the recent Apple M1 laptops.

Yours,
Linus Walleij
