[PATCH 0/3] spi: davinci: move eventq parameter to platform data

[PATCH 0/3] spi: davinci: move eventq parameter to platform data

[Michael Williamson]

For DMA operation, the davinci spi driver needs an eventq number.
Currently, this number is passed as a IORESOURCE_DMA.  This is not
correct, as the eventq is not a DMA channel.  Pass the eventq
via the platform data structure instead as is done with davinci
devices such as the McASP.

Two platforms (dm355 and dm365) are using the davinci spi driver 
with DMA's enabled, move the eventq parameter out of the resources
and into the platform data.

I have tested this patch with an OMAP-L138 (patch submission for this
platform is in progress).  I do not have a dm355 or dm365, so these
platforms have not been tested.

    It makes sense to merge this patch with the patches 2 and 3 as otherwise 
the bisectability is prevented for DM3[56]5 -- their 'dma_event_q' field will 
be anonymously initialized to 0 after this patch but should be 1 and 3 instead 
correspondingly. Although, this doesn't seem to be a fatal defect, so the 
patches can be kept separate... Don't know what's better.

Barring any other comments, I will collapse the patches and resend.  
I will correct the typo you mentioned above as well.

>    It makes sense to merge this patch with the patches 2 and 3 as otherwise the bisectability is prevented for DM3[56]5 -- their 'dma_event_q' field will be anonymously initialized to 0 after this patch but should be 1 and 3 instead correspondingly. Although, this doesn't seem to be a fatal defect, so the patches can be kept separate... Don't know what's better.

Barring any other comments, I will collapse the patches and resend.  
I will correct the typo you mentioned above as well.

Thanks.
