Hmm, that's probably what comment in omap3-n900.dts is saying: "sys_ndmareq1 could be used by the driver, not as gpio65 though" However board-rx51 (is that n900?) is using it as gpio pin. Also omap2420-n8x0-common.dtsi comment says: "gpio-irq for dma: 26" and it matches board-n8x0.c platform data configuration. But I still missing pinmux configuration as we need to add it into DT as well. I guess this was originally done in bootloader. Any hint where can I get this info from?
