[PATCH 1/3] ARM: dts: imx6sx: Fix SAI DMA index

[PATCH 1/3] ARM: dts: imx6sx: Fix SAI DMA index

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@nxp.com>

According to sdma_peripheral_type in include/linux/platform_data/dma-imx.h
IMX_DMATYPE_SAI corresponds to index 24, so fix it accordingly.

[PATCH 2/3] ARM: dts: imx6sx: Remove unused property

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@nxp.com>

Property 'dma-source' is not used anywhere, not it is documented, so
let's just get rid of it.
