Hello All,

 

Porting UART software from Linux 2.6 to Linux 3.2 kernel, which uses SDMA APIs(mentioned below) . I do see a lot of interfaces are changed in 3.2 kernel . I am looking some information how to  fulfill below interfaces.

 

Linux 2.6 interfaces

----------------------

mxc_dma_request         -- Not there in Linux 3.2 kernel

mxc_dma_config           -- Not there in Linux 3.2 kernel

mxc_dma_callback_set -- Not there in Linux 3.2 kernel

mxc_dma_enable         -- Not there in Linux 3.2 kernel

 

Can any one let me know where can i find patch for this interfaces ?  What types of interfaces i need to use to get similar functionality.
