From 1b359d32f2b652032e056b79b20a7e1af7cf8ed2 Mon Sep 17 00:00:00 2001 From: Adam Ford Date: Wed, 9 Oct 2019 14:20:53 -0500 Subject: [PATCH] ARM: dts: logicpd-torpedo: Disable Bluetooth Serial DMA The default serial driver for omap2plus is the 8250_omap driver. Unfortunately, this driver does not yet appear to have fully functional DMA on OMAP3630/DM3730 which causes some timeouts and frame errors. This patch removes the DMA entry from the device tree which allow the UART to operate without Bluetooth frame errors. If/when DMA is working on OMAP3630, this should be reverted.
