Subject: [Bug]: mtd: onenand: omap2plus: kernel panic with OneNAND on OMAP3 (DM3730) device GTA04A5
Hi,
we just started testing the v4.16 kernel and found the
device no longer bootable (works with v4.15). It turned
out that there was a harmful modification somewhere between
v4.15.0 and v4.16-rc1.
A git bisect points to this patch:
commit bdaca9345d41fd9420995469d27603ea62054691
Author: Ladislav Michl <ladis@...ux-mips.org>
Date: Fri Jan 12 14:16:57 2018 +0100
mtd: onenand: omap2: Decouple DMA enabling from INT pin availability
INT pin (gpio_irq) is not really needed for DMA but only for notification
when a command that needs wait has completed. DMA memcpy can be still used
even without gpio_irq available, so enable it unconditionally.

Kernel panic log is attached which indeed indicates a DMA problem.
Note that we have added compatible = "ti,omap2-onenand";
Any suggestions, fixes?
BR and thanks,
