Subject[BISECTED, REGRESSION] OMAP3 onenand/DMA broken
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
[ 8.395751] omap2-onenand 1000000.onenand: timeout waiting for DMA
[ 8.425750] omap2-onenand 1000000.onenand: timeout waiting for DMA

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