[PATCH] ARM: dts: ixp4xx: Add Omicron device trees
From: Linus Walleij <hidden>
Date: 2021-07-19 12:25:46
This coverts all the Omicron devices found in the Omicron boardfile to device tree. The Omicron devices board file was added in 2011. Cc: Richard Cochran <richardcochran@gmail.com> Signed-off-by: Linus Walleij <redacted> --- Richard: it would be great if you can test this or at least sanity check my DTS files so we can migrate the board files. --- arch/arm/boot/dts/Makefile | 5 +- .../boot/dts/intel-ixp42x-omicron-devixp.dts | 19 +++ .../boot/dts/intel-ixp42x-omicron-mic256.dts | 31 +++++ .../boot/dts/intel-ixp42x-omicron-miccpt.dts | 62 ++++++++++ arch/arm/boot/dts/intel-ixp42x-omicron.dtsi | 114 ++++++++++++++++++ 5 files changed, 230 insertions(+), 1 deletion(-) create mode 100644 arch/arm/boot/dts/intel-ixp42x-omicron-devixp.dts create mode 100644 arch/arm/boot/dts/intel-ixp42x-omicron-mic256.dts create mode 100644 arch/arm/boot/dts/intel-ixp42x-omicron-miccpt.dts create mode 100644 arch/arm/boot/dts/intel-ixp42x-omicron.dtsi
