Adds peripherals required to allow booting: Interrupt Controller, Clock, Generic ARMv7 Timers, Synopsys Timer, Flexcoms, GPIOs. Also adds other peripherals like crypto(AES/SHA), DMA, Watchdog Timer, TRNG and MCAN0. Signed-off-by: Kavyasree Kotagiri --- v5 -> v6: - Renamed dts file to lan966x-pcb8291.dts file. - Disabled optional watchdog in dtsi file and enabled it in dts file. v4 -> v5: - Modified AES, SHA, TRNG node names as per generic names recommended. v3 -> v4: - Removed character 'x' from compatible string. - Removed memory node as handled by bootloader. - Renamed flexcom3 usart0 to usart3 - Added /chosen and /aliases nodes in dts file. v2 -> v3: - Enabling trng in dtsi itself. - Removed "status=okay" dma0. - Add gpio pin settings for can0(missed adding this in previous version) v1 -> v2: - Moved flx3 usart0 node to dtsi file. - Removed status="okay" for dma0 to maintain consistency across nodes (which means enabling dma0 by default) arch/arm/boot/dts/Makefile | 2 + arch/arm/boot/dts/lan966x-pcb8291.dts | 64 +++++++ arch/arm/boot/dts/lan966x.dtsi | 238 ++++++++++++++++++++++++++ 3 files changed, 304 insertions(+) create mode 100644 arch/arm/boot/dts/lan966x-pcb8291.dts create mode 100644 arch/arm/boot/dts/lan966x.dtsi diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile index 235ad559acb2..c17a7308ff44 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -735,6 +735,8 @@ dtb-$(CONFIG_SOC_IMX7D) += \ dtb-$(CONFIG_SOC_IMX7ULP) += \ imx7ulp-com.dtb \ imx7ulp-evk.dtb +dtb-$(CONFIG_SOC_LAN966) += \ + lan966x-pcb8291.dtb dtb-$(CONFIG_SOC_LS1021A) += \ ls1021a-moxa-uc-8410a.dtb \ ls1021a-qds.dtb \ diff --git a/arch/arm/boot/dts/lan966x-pcb8291.dts b/arch/arm/boot/dts/lan966x-pcb8291.dts new file mode 100644 index 000000000000..3281af90ac6d --- /dev/null +++ b/arch/arm/boot/dts/lan966x-pcb8291.dts @@ -0,0 +1,64 @@ +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) +/* + * lan966x_pcb8291.dts - Device Tree file for PCB8291 + */ +/dts-v1/;
