This is the first generation Amazon Echo from 2016. Audio support is not yet implemented. Signed-off-by: André Hentschel <nerv@xxxxxxxxxxx> --- v2: Don't disable sgx, as the previous patch changes dtsi files accordingly I have local patches for the microphone array, but cleaning that up will take some time. Audio output seems to be even harder work... You can find a tutorial on how to boot the Echo here: https://labs.f-secure.com/archive/alexa-are-you-listening/ arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/omap3-echo.dts | 462 +++++++++++++++++++++++++++++++ 2 files changed, 463 insertions(+) create mode 100644 arch/arm/boot/dts/omap3-echo.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index b21b3a64641a..923dabc09203 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -685,6 +685,7 @@ dtb-$(CONFIG_ARCH_OMAP3) += \ omap3-devkit8000.dtb \ omap3-devkit8000-lcd43.dtb \ omap3-devkit8000-lcd70.dtb \ + omap3-echo.dtb \ omap3-evm.dtb \ omap3-evm-37xx.dtb \ omap3-gta04a3.dtb \ diff --git a/arch/arm/boot/dts/omap3-echo.dts b/arch/arm/boot/dts/omap3-echo.dts new file mode 100644 index 000000000000..6884278db220 --- /dev/null +++ b/arch/arm/boot/dts/omap3-echo.dts @@ -0,0 +1,462 @@ +// SPDX-License-Identifier: GPL-2.0-only +/* + * Copyright (C) 2019 André Hentschel <nerv@xxxxxxxxxxx> + */ +/dts-v1/;
