This document describes how to test the DMA support for R-Car Gen-3 SoCs in the SDHI driver.

Kernel Version and Configuration
DMA support R-Car Gen3 SoCs for the SDHI driver is currently available in a topic branch:

git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas.git topic/sdhi-gen3-dma

For the tests described here the kernel was compiled with the arm64 defconfig. MMC_SDHI was also enabled.

It is critical that MMC_SDHI is enabled for this testing.
