[PATCH 0/2] ARM: OMAP1/OMAP2+: Add dma_slave_map to board files

From: Peter Ujfalusi <hidden>
Date: 2016-02-02 14:28:41 

Hi,

The following series adds the dma_slave map to the sDMA (omap-dma) driver. The
dma_slave_map is needed later when we convert drivers to use the new dmaengine
API for requesting slave channels.

Regards,
Peter

[PATCH 1/2] ARM: OMAP1: DMA: Provide dma_slave_map to omap-dma

From: Peter Ujfalusi <hidden>
Date: 2016-02-02 14:27:54 

OMAP1 can not boot in DT mode and to be able to clean up the driver
regarding to the dmaengine API use (switching to the new API) the
device/slave -> filter mapping needs to be provided to the omap-dma driver.

Thanks Aaro,

I believe the map covers all drivers using DMA, but in case I missed any we -
you ;) will notice it as they will fail to get the DMA channels. This only
going to be visible after I send the driver changes for 4.7. In such a case we
will need to add the given device to the list.

Yeah makes sense. Applying both into omap-for-v4.6/soc thanks.

[PATCH 2/2] ARM: OMAP2+: DMA: Provide dma_slave_map to omap-dma for legacy boot

From: Peter Ujfalusi <hidden>
Date: 2016-02-02 14:27:56 

We still have some boards booting in legacy mode and they will need to have
the device/slave -> filter_fn mapping so we can convert the OMAP drivers
to use the new dmaengine API for requesting channels.
Only some OMAP24xx and OMAP3xxx boards can boot in legacy mode which means
we only need to provide the map for these SoCs.
