Since you are using single FIFO configuration, which SDMA script are you using? This should reflects in the Device Tree. As far as I learned, FSL 3.14 is using number 22 for SSIs which is the one for Dual FIFO Mode.
No! Currently is 1. Here the Freescale's v3.14.28 GA imx6sx.dtsi entry
ssi1: ssi@02028000 { compatible = "fsl,imx6sx-ssi", "fsl,imx21-ssi"; reg = <0x02028000 0x4000>; interrupts = <GIC_SPI 46 IRQ_TYPE_LEVEL_HIGH>; clocks = <&clks IMX6SX_CLK_SSI1_IPG>, <&clks IMX6SX_CLK_SSI1>; clock-names = "ipg", "baud"; dmas = <&sdma 37 1 0>, <&sdma 38 1 0>; dma-names = "rx", "tx"; status = "disabled"; };
Take a look at imx_3.14.38_6ul_ga branch; It does use 22 in the dmas nodes: http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/arch/arm/bo...
However, this list is only about mainline kernel, so please run all your tests with mainline instead of FSL 3.14.
Ok! I'm doing that right now.
