Subject: [PATCH] ARM: dts: rockchip: Add DMA tx and rx channels in UART interfaces for RK3288 SoCs
Date: Tue, 16 Jun 2015 17:19:26 +0000	[thread overview]
Message-ID: <1434475166-30338-1-git-send-email-romain.perier@gmail.com> (raw)

This enable DMA capability for the corresponding UART interfaces, also it removes
warning "ttyS%d - Failed to request dma" from kernel logs.

Changes since v1 ("[PATCH] ARM: dts: rockchip: Add dmac_bus rx and tx for uart2"):
	- Add DMA tx and rx channels for all UART interfaces
	- Rename commit summary
