I applied this patch: and omap-aes driver was successfully loaded. now it is in /proc/crypto I copied dma names and numbers from file arch/arm/mach-omap2/omap_hwmod_3xxx_data.c diff --git a/arch/arm/boot/dts/omap3.dtsi b/arch/arm/boot/dts/omap3.dtsi index 01b7111..473d460 100644 --- a/arch/arm/boot/dts/omap3.dtsi +++ b/arch/arm/boot/dts/omap3.dtsi @@ -92,6 +92,8 @@ ti,hwmods = "aes"; reg = <0x480c5000 0x50>; interrupts = <0>; + dmas = <&sdma 65 &sdma 66>; + dma-names = "tx", "rx"; }; prm: prm@48306000 { @@ -550,6 +552,8 @@ ti,hwmods = "sham"; reg = <0x480c3000 0x64>; interrupts = <49>; + dmas = <&sdma 96>; + dma-names = "rx"; }; smartreflex_core: smartreflex@480cb000 {
