I tried testing this patch on my OMAP-L138 EVM, but SPI fails to 
initialize after applying the patch.

root@arago:~# dmesg | grep -i spi                                               
spi_davinci spi_davinci.1: request RX DMA channel failed                        

without these 3 patches, SPI flash is detected fine (same kernel 
configuration):

root@arago:~# dmesg | grep spi                                                  
spi_davinci spi_davinci.1: DMA: supported                                       
spi_davinci spi_davinci.1: DMA: RX channel: 18, TX channel: 19, event queue: 0  
spi_davinci spi_davinci.1: master is unqueued, this is deprecated               
m25p80 spi1.0: m25p64 (8192 Kbytes)                                             
spi_davinci spi_davinci.1: Controller at 0xfef0e000                             

Any idea what could be wrong? This is v3.6-rc3 kernel. I can provide 
full bootlogs or any other debug information if that helps.

Thanks,
Sekhar
