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
