looks like i've found it:
when reverting these 2 (latter alone was not enough and seems not fixing the timeout as shown in my trace)
Revert "spi: mediatek: Enable irq when pdata is ready" (HEAD -> 6.2-rc)
Revert "spi: spi-mtk-nor: Add recovery mechanism for dma read timeout"
so this breaks spi on mt7986:
c6f7874687f7 2022-11-28 spi: mediatek: Enable irq when pdata is ready
have sent bug-report to mailinglist and author/reviewer/maintainer...
