| From | Lee Jones <> | Subject | [PATCH 03/63] ARM: ux500: Supply UART's DMA configuration via Device Tree | Date | Fri, 3 May 2013 15:31:49 +0100 |
| |
When requesting a channel, a DMA client needs to pass some pieces of information such as; request channel, device type, channel type and direction etc. Normally we do this in the form of platform data, but when DT is enabled we need to pass it using the driver's bindings instead.
