-Subject: [PATCH] ARM: bcm283x: Enable DMA support for SPI controller
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Without this, the driver for the BCM2835 SPI controller uses interrupt
-mode instead of DMA mode, incurring a significant performance penalty.
-The Foundation's device tree has had these attributes for years, but for
-some reason they were never upstreamed.
-
-They were originally contributed by Noralf Trønnes and Martin Sperl:
-https://github.com/raspberrypi/linux/commit/25f3e064afc8
-https://github.com/raspberrypi/linux/commit/e0edb52b47e6
-
-The DREQ numbers 6 and 7 are documented in section 4.2.1.3 of:
-https://www.raspberrypi.org/app/uploads/2012/02/BCM2835-ARM-Peripherals.pdf
