From 06c1258a0a19597ddec954e0c55a5be585c0d8a5 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Stefan=20Br=C3=BCns?= Date: Thu, 28 Sep 2017 03:49:27 +0200 Subject: [PATCH] arm64: allwinner: a64: add dma controller references to spi nodes MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The spi controller nodes omit the dma controller/channel references, add it. This does not yet enable DMA for SPI transfers, as the spi-sun6i driver lacks support for DMA, but always uses PIO to the FIFO.
