Add register sets used for access by the DMA engine, and DMA properties to the MSIOF nodes.
Signed-off-by: Geert Uytterhoeven <[email protected]> --- The format of the DMA specifiers depends on the DT bindings for SHDMA, which are still under development. This patch has been sent before as part of the series "[PATCH/RFC 0/7] ARM: shmobile: r8a7791: Add preliminary DMA support". Changes: - Add register sets for DMA, - Reorder: TX first, RX second. arch/arm/boot/dts/r8a7791.dtsi | 15 ++++++++++++--- 1 file changed, 12 insertions(+), 3 deletions(-) diff --git a/arch/arm/boot/dts/r8a7791.dtsi b/arch/arm/boot/dts/r8a7791.dtsi index 98fdd88462e2..1f8a4605e1e3 100644 --- a/arch/arm/boot/dts/r8a7791.dtsi +++ b/arch/arm/boot/dts/r8a7791.dtsi @@ -1005,9 +1005,12 @@ msiof0: spi@e6e20000 { compatible = "renesas,msiof-r8a7791"; - reg = <0 0xe6e20000 0 0x0064>; + reg = <0 0xe6e20000 0 0x0064>, <0 0xe7e20000 0 0x0064>; interrupts = <0 156 IRQ_TYPE_LEVEL_HIGH>; clocks = <&mstp0_clks R8A7791_CLK_MSIOF0>; + dmas = <&dma0 R8A7791_DMA_MSIOF0_TX CHCR_TX_32BIT>, + <&dma0 R8A7791_DMA_MSIOF0_RX CHCR_RX_32BIT>; + dma-names = "tx", "rx"; #address-cells = <1>; #size-cells = <0>; status = "disabled"; @@ -1015,9 +1018,12 @@ msiof1: spi@e6e10000 { compatible = "renesas,msiof-r8a7791"; - reg = <0 0xe6e10000 0 0x0064>; + reg = <0 0xe6e10000 0 0x0064>, <0 0xe7e10000 0 0x0064>; interrupts = <0 157 IRQ_TYPE_LEVEL_HIGH>; clocks = <&mstp2_clks R8A7791_CLK_MSIOF1>; + dmas = <&dma0 R8A7791_DMA_MSIOF1_TX CHCR_TX_32BIT>, + <&dma0 R8A7791_DMA_MSIOF1_RX CHCR_RX_32BIT>; + dma-names = "tx", "rx"; #address-cells = <1>; #size-cells = <0>; status = "disabled"; @@ -1025,9 +1031,12 @@ msiof2: spi@e6e00000 { compatible = "renesas,msiof-r8a7791"; - reg = <0 0xe6e00000 0 0x0064>; + reg = <0 0xe6e00000 0 0x0064>, <0 0xe7e00000 0 0x0064>; interrupts = <0 158 IRQ_TYPE_LEVEL_HIGH>; clocks = <&mstp2_clks R8A7791_CLK_MSIOF2>; + dmas = <&dma0 R8A7791_DMA_MSIOF2_TX CHCR_TX_32BIT>, + <&dma0 R8A7791_DMA_MSIOF2_RX CHCR_RX_32BIT>; + dma-names = "tx", "rx"; #address-cells = <1>; #size-cells = <0>; status = "disabled"; -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
