ARM64: dts: apalis-imx8: disable dma for lpuart 2 again
lpuart2 is the only UART where DMA request works and linux tries to use a DMA. However this DMA does not work and output hangs, disbling the DMA works for now. This change was originally introduced in commit 1a8badaa585de ARM64: dts: apalis-imx8: disable dma for lpuart2 but lost when doing the devicetree-split. Fixes: 2715972aadc8f arm64: dts: apalis-imx8: separate common module pa Related-to: ELB-3178 Signed-off-by: Philippe Schenker <>
