Hi,

When booting v5.4 (or v5.5-rc4) on N900, the console gets flooded with:

[    8.335754] omap2-onenand 1000000.onenand: timeout waiting for DMA
[    8.365753] omap2-onenand 1000000.onenand: timeout waiting for DMA

[    8.485748] omap2-onenand 1000000.onenand: timeout waiting for DMA

[    8.575775] omap2-onenand 1000000.onenand: timeout waiting for DMA

making the system unusable.

    dmaengine: ti: omap-dma: Improved memcpy polling support

The commit does not revert cleanly anymore. Any ideas how to fix this?
