Add support for CompuLab CM-SOM-AM57X board. CL-SOM-AM57x is a miniature System-on-Module (SoM) based on TI Sitara AM57x ARM Cortex-A15 System-on-Chip family. https://www.compulab.co.il/products/computer-on-modules/cl-som-am57x-ti-am5728-am5718-system-on-module/ Add basic DT support for standalone module (without a carrier board): * Memory configuration * Heartbeat led * I2C1 and I2C4 * PMIC * SATA Signed-off-by: Dmitry Lifshitz <lifshitz@xxxxxxxxxxxxxx> Acked-by: Igor Grinberg <grinberg@xxxxxxxxxxxxxx> --- v3: * Move PMIC to I2C4 * Reformat subject v2: * Fixed voltages (for OPP_HIGH) for VDD_GPU, VDD_IVA, VDD_DSPEVE * Added comments for VDDA_1V8_PHYA/B * Add "regulator-always-on" property for ldousb_reg .../devicetree/bindings/arm/omap/omap.txt | 3 + arch/arm/boot/dts/Makefile | 3 +- arch/arm/boot/dts/am57xx-cl-som-am57x.dts | 274 +++++++++++++++++++++ 3 files changed, 279 insertions(+), 1 deletion(-) create mode 100644 arch/arm/boot/dts/am57xx-cl-som-am57x.dts diff --git a/Documentation/devicetree/bindings/arm/omap/omap.txt b/Documentation/devicetree/bindings/arm/omap/omap.txt index da84372..dd53c90 100644 --- a/Documentation/devicetree/bindings/arm/omap/omap.txt +++ b/Documentation/devicetree/bindings/arm/omap/omap.txt @@ -156,6 +156,9 @@ Boards: - AM437x SK EVM: AM437x StarterKit Evaluation Module compatible = "ti,am437x-sk-evm", "ti,am4372", "ti,am43" +- AM57XX CL-SOM-AM57x + compatible = "compulab,cl-som-am57x", "ti,am5728", "ti,dra742", "ti,dra74", "ti,dra7" + - DRA742 EVM: Software Development Board for DRA742 compatible = "ti,dra7-evm", "ti,dra742", "ti,dra74", "ti,dra7" diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 5492a24..803a020 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -477,8 +477,9 @@ dtb-$(CONFIG_SOC_OMAP5) += \ omap5-sbc-t54.dtb \ omap5-uevm.dtb dtb-$(CONFIG_SOC_DRA7XX) += \ - dra7-evm.dtb \ am57xx-beagle-x15.dtb \ + am57xx-cl-som-am57x.dtb \ + dra7-evm.dtb \ dra72-evm.dtb dtb-$(CONFIG_ARCH_ORION5X) += \ orion5x-lacie-d2-network.dtb \ diff --git a/arch/arm/boot/dts/am57xx-cl-som-am57x.dts b/arch/arm/boot/dts/am57xx-cl-som-am57x.dts new file mode 100644 index 0000000..087d62e --- /dev/null +++ b/arch/arm/boot/dts/am57xx-cl-som-am57x.dts @@ -0,0 +1,274 @@ +/* + * Support for CompuLab CL-SOM-AM57x System-on-Module + * + * Copyright (C) 2015 CompuLab Ltd. - http://www.compulab.co.il/ + * Author: Dmitry Lifshitz <lifshitz@xxxxxxxxxxxxxx> + * + * This program is free software;
