ARM: dts: keystone: Use dma-ranges property
The dma-ranges property has to be specified per bus and has format: < DMA addr > - Base DMA address for Bus (Bus format 32-bits) < CPU addr > - Corresponding base CPU address (CPU format 64-bits) < DMA range size > - Size of supported DMA range Cc: Russell King <linux@arm.linux.org.uk> Cc: Arnd Bergmann <arnd@arndb.de> Cc: Olof Johansson <olof@lixom.net> Cc: Grant Likely <grant.likely@linaro.org> Cc: Rob Herring <robh+dt@kernel.org> Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com> Signed-off-by: Santosh Shilimkar <santosh.shilimkar@ti.com>
