at first look it seems it is needed...as i get this trace with 6.2:

[    2.145931] pc : mtk_spi_can_dma+0x0/0x34
[    2.155212] lr : mtk_spi_interrupt+0x74/0x360

[    2.091801] mtk-spi 1100a000.spi: spi-mem transfer timeout
[    2.097310] spi-nor: probe of spi0.0 failed with error -110
[    2.102930] Unable to handle kernel read from unreadable memory at virtual address 0000000000000010

but i get the same trace when reverting the cs-gpios change....seems something is broken in 6.2-rc1

6.1 works without the bogus cs-gpios (and the mt7531 interrupt-change)...

have tried reverting this commit, but it does not fix the issue:

8330e9e8269b 2022-12-07 spi: spi-mtk-nor: Add recovery mechanism for dma read timeout

any idea without doing a bisect?
