Hi,

the following commit breaks SPIM-NOR on mt7986:

c6f7874687f7 2022-11-28 spi: mediatek: Enable irq when pdata is ready

> [    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

after reverting the commit, no trace happens and nor is recognized on my board
