Hmmm, Louis (which already was in the CC) posted a patch with a Fixes:
tag referencing that commit more than a month ago:

spi: omap2-mcspi: Ensure that CS is correctly asserted when switching
from MULTI mode to SINGLE mode
https://lore.kernel.org/all/20240506-fix-omap2-mcspi-v2-1-d9c77ba8b9c7@bootlin.com/

Unless I'm missing something, that patch did not make much progress
since then. But I wonder if that might help. Louis? FWIW, this thread
starts here with João problem description:
https://lore.kernel.org/all/20240612170030.3qatttsgrwjg2m5s@joaog-nb/

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)
