Original submission was done by Andrey Gusakov, but he is too busy on other projects, so the honors of submitting this were delegated to me. NOTE: RAVE SP ("zii,rave-sp-esb") node is technically supported by upstream, but it needs some fixes from [rave-sp-fixes] to work correctly. If you want me to drop that node until [rave-sp-fixes] is merged, let me know. NOTE: This patch is currently generated to be on top of [mezz], but that can be easily change should it be accepted first Changes since [v0]: - Patch converted to be a standalone file not dependent on any ZII-specific .dtsi - Added RAVE SP node with all the children that are currently supported by upstream - Droppped ecspi2 node. That node didn't have any child devices in [v0] because none of the chips connected to that bus are supported upstream. This node can be added later once anything attached to it has upstream drivers. - Dropped i2c_gpio. That bus was originally added for RAVE SP related prototyping and is unused in actual product. - Various newline fixes pointed out in [v0] - Most of then nodes should be sorted alphabetically (I might have missed some) - Collected Reviewed-by from Fabio (Fabio, I assumed you won't mind, but let me know if you want me to drop it) [mezz] lkml.kernel.org/r/20180707024902.439-1-andrew.smirnov@gmail.com [v0] lkml.kernel.org/r/1529603100-31958-3-git-send-email-andrey.gusakov@cogentembedded.com [rave-sp-fixes] lkml.kernel.org/r/20180707024108.32373-1-andrew.smirnov@gmail.com arch/arm/boot/dts/Makefile | 3 +- arch/arm/boot/dts/imx51-zii-scu3-esb.dts | 459 +++++++++++++++++++++++ 2 files changed, 461 insertions(+), 1 deletion(-) create mode 100644 arch/arm/boot/dts/imx51-zii-scu3-esb.dts diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 1d6acbab7062..bea41b129493 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -359,7 +359,8 @@ dtb-$(CONFIG_SOC_IMX51) += \ imx51-eukrea-mbimxsd51-baseboard.dtb \ imx51-ts4800.dtb \ imx51-zii-rdu1.dtb \ - imx51-zii-scu2-mezz.dtb + imx51-zii-scu2-mezz.dtb \ + imx51-zii-scu3-esb.dtb dtb-$(CONFIG_SOC_IMX53) += \ imx53-ard.dtb \ imx53-cx9020.dtb \ diff --git a/arch/arm/boot/dts/imx51-zii-scu3-esb.dts b/arch/arm/boot/dts/imx51-zii-scu3-esb.dts new file mode 100644 index 000000000000..2941a92d40f1 --- /dev/null +++ b/arch/arm/boot/dts/imx51-zii-scu3-esb.dts @@ -0,0 +1,459 @@ +// SPDX-License-Identifier: (GPL-2.0 OR MIT) + +/* + * Copyright (C) 2018 Zodiac Inflight Innovations + */ + +/dts-v1/;
