From 38fd90a3e1ac7e948081cf168cf10f0a20febc21 Mon Sep 17 00:00:00 2001 From: Manorit Chawdhry Date: Mon, 2 Sep 2024 17:56:52 +0530 Subject: [PATCH] arm64: dts: ti: Introduce J742S2 SoC family This device is a subset of J784S4 and shares the same memory map and thus the nodes are being reused from J784S4 to avoid duplication. Here are some of the salient features of the J742S2 automotive grade application processor: The J742S2 SoC belongs to the K3 Multicore SoC architecture platform, providing advanced system integration in automotive, ADAS and industrial applications requiring AI at the network edge. This SoC extends the K3 Jacinto 7 family of SoCs with focus on raising performance and integration while providing interfaces, memory architecture and compute performance for multi-sensor, high concurrency applications. Some changes that this devices has from J784S4 are: * 4x Cortex-A72 vs 8x Cortex-A72 * 3x C7x DSP vs 4x C7x DSP * 4 port ethernet switch vs 8 port ethernet switch ( Refer Table 2-1 for Device comparison with J7AHP ) Link: https://www.ti.com/lit/pdf/spruje3 (TRM) Reviewed-by: Beleswar Padhi Signed-off-by: Manorit Chawdhry Link: https://lore.kernel.org/r/20240902-b4-upstream-j742s2-v6-4-6a7aa2736797@ti.com Signed-off-by: Vignesh Raghavendra --- arch/arm64/boot/dts/ti/k3-j742s2-main.dtsi | 45 ++++++++++ arch/arm64/boot/dts/ti/k3-j742s2.dtsi | 98 ++++++++++++++++++++++ 2 files changed, 143 insertions(+) create mode 100644 arch/arm64/boot/dts/ti/k3-j742s2-main.dtsi create mode 100644 arch/arm64/boot/dts/ti/k3-j742s2.dtsi diff --git a/arch/arm64/boot/dts/ti/k3-j742s2-main.dtsi b/arch/arm64/boot/dts/ti/k3-j742s2-main.dtsi new file mode 100644 index 000000000000..b320c27f7afe --- /dev/null +++ b/arch/arm64/boot/dts/ti/k3-j742s2-main.dtsi @@ -0,0 +1,45 @@ +// SPDX-License-Identifier: GPL-2.0-only OR MIT +/* + * Device Tree Source for J742S2 SoC Family + * + * TRM: https://www.ti.com/lit/pdf/spruje3 + * + * Copyright (C) 2024 Texas Instruments Incorporated - https://www.ti.com/ + * + */ + +&c71_0 { + firmware-name = "j742s2-c71_0-fw"; +}; + +&c71_1 { + firmware-name = "j742s2-c71_1-fw"; +}; + +&c71_2 { + firmware-name = "j742s2-c71_2-fw"; +}; + +&main_r5fss0_core0 { + firmware-name = "j742s2-main-r5f0_0-fw"; +}; + +&main_r5fss0_core1 { + firmware-name = "j742s2-main-r5f0_1-fw"; +}; + +&main_r5fss1_core0 { + firmware-name = "j742s2-main-r5f1_0-fw"; +}; + +&main_r5fss1_core1 { + firmware-name = "j742s2-main-r5f1_1-fw"; +}; + +&main_r5fss2_core0 { + firmware-name = "j742s2-main-r5f2_0-fw"; +}; + +&main_r5fss2_core1 { + firmware-name = "j742s2-main-r5f2_1-fw"; +}; diff --git a/arch/arm64/boot/dts/ti/k3-j742s2.dtsi b/arch/arm64/boot/dts/ti/k3-j742s2.dtsi new file mode 100644 index 000000000000..7a72f82f56d6 --- /dev/null +++ b/arch/arm64/boot/dts/ti/k3-j742s2.dtsi @@ -0,0 +1,98 @@ +// SPDX-License-Identifier: GPL-2.0-only OR MIT +/* + * Device Tree Source for J742S2 SoC Family + * + * TRM: https://www.ti.com/lit/pdf/spruje3 + * + * Copyright (C) 2024 Texas Instruments Incorporated - https://www.ti.com/ + * + */ +#include "k3-j784s4-j742s2-common.dtsi" + +/ { + model = "Texas Instruments K3 J742S2 SoC"; + compatible = "ti,j742s2"; + + cpus { + #address-cells = <1>; + #size-cells = <0>; + + cpu-map { + cluster0: cluster0 { + core0 { + cpu = <&cpu0>; + }; + + core1 { + cpu = <&cpu1>; + }; + + core2 { + cpu = <&cpu2>; + }; + + core3 { + cpu = <&cpu3>; + }; + }; + }; + + cpu0: cpu@0 { + compatible = "arm,cortex-a72"; + reg = <0x000>; + device_type = "cpu"; + enable-method = "psci"; + i-cache-size = <0xc000>; + i-cache-line-size = <64>; + i-cache-sets = <256>; + d-cache-size = <0x8000>; + d-cache-line-size = <64>; + d-cache-sets = <256>; + next-level-cache = <&L2_0>; + }; + + cpu1: cpu@1 { + compatible = "arm,cortex-a72"; + reg = <0x001>; + device_type = "cpu"; + enable-method = "psci"; + i-cache-size = <0xc000>; + i-cache-line-size = <64>; + i-cache-sets = <256>; + d-cache-size = <0x8000>; + d-cache-line-size = <64>; + d-cache-sets = <256>; + next-level-cache = <&L2_0>; + }; + + cpu2: cpu@2 { + compatible = "arm,cortex-a72"; + reg = <0x002>; + device_type = "cpu"; + enable-method = "psci"; + i-cache-size = <0xc000>; + i-cache-line-size = <64>; + i-cache-sets = <256>; + d-cache-size = <0x8000>; + d-cache-line-size = <64>; + d-cache-sets = <256>; + next-level-cache = <&L2_0>; + }; + + cpu3: cpu@3 { + compatible = "arm,cortex-a72"; + reg = <0x003>; + device_type = "cpu"; + enable-method = "psci"; + i-cache-size = <0xc000>; + i-cache-line-size = <64>; + i-cache-sets = <256>; + d-cache-size = <0x8000>; + d-cache-line-size = <64>; + d-cache-sets = <256>; + next-level-cache = <&L2_0>; + }; + }; +}; + +#include "k3-j742s2-main.dtsi" -- 2.50.1
