This patch adds minimal SoC support by including next Device Tree nodes: 1. Octa cores (Cortex-A55), supporting PSCI v1.0 2. ARM architecture timer (armv8-timer) 3. Interrupt controller (GIC-400) 4. Pinctrl nodes for GPIO 5. Serial node Signed-off-by: Sam Protsenko --- Changes in v3: - Used generic fixed clock for serial Changes in v2: * Commit message: - Documented added dts features instead of CPU features * exynos850-usi.dtsi: - Removed, moved everything to exynos850.dtsi * exynos850.dtsi: - Root node: - Added comment about engineering name (Exynos3830) - Renamed pinctrl nodes, adding domain names - Used hard coded IRQ numbers instead of named constants everywhere - Added soc node, moved next nodes there: gic, clock, pinctrls and serial - Used address-cells=1 for soc node and removed unneeded 0x0 from reg properties - Moved exynos850-pinctrl.dtsi include line to the end of exynos850.dtsi - Coding style fixes - cpus: - Used address-cells=1 for cpus node - Renamed cpu@0001 to cpu@1, and so on - Left only "arm,cortex-a55" for cpus compatible - Renamed reg = <0x0001> to <0x1> for cpus - armv8 timer: - Add comment about missing HV timer IRQ to armv8 timer node - Removed not existing properties from armv8 timer node - Fixed cpu number in CPU_MASK() - Removed obsolete clock-frequency property - GIC: - Fixed GIC type to be GIC-400 - Fixed size of GIC's 2nd region to be 0x2000 - serial node: - Hard coded clock number for serial_0 for now; will replace with named const once proper clock driver is implemented - Removed gate_uart_clk0 clock from serial_0, as that clock is not supported in serial driver anyway (yet) - clock node: - Fixed clock controller node name (@0x12.. -> @12..) * exynos850-pinctrl.dtsi: - Referenced pinctrl nodes instead of defining those again in root node - Fixed interrupt-cells (3 -> 2) - Fixed USI related comments for pin config nodes - Removed decon_f_te_* and fm_lna_en nodes (won't be used) - Reordered pin config nodes by pin numbers - Improved all comments - Used existing named constants for pin-function and pin-pud - Fixed node names (used hyphens instead of underscore) - Fixed warnings found in W=1 build .../boot/dts/exynos/exynos850-pinctrl.dtsi | 748 ++++++++++++++++++ arch/arm64/boot/dts/exynos/exynos850.dtsi | 261 ++++++ 2 files changed, 1009 insertions(+) create mode 100644 arch/arm64/boot/dts/exynos/exynos850-pinctrl.dtsi create mode 100644 arch/arm64/boot/dts/exynos/exynos850.dtsi -- 2.30.2 diff --git a/arch/arm64/boot/dts/exynos/exynos850-pinctrl.dtsi b/arch/arm64/boot/dts/exynos/exynos850-pinctrl.dtsi new file mode 100644 index 000000000000..ba5d5f33e2f6 --- /dev/null +++ b/arch/arm64/boot/dts/exynos/exynos850-pinctrl.dtsi @@ -0,0 +1,748 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * Samsung's Exynos850 SoC pin-mux and pin-config device tree source + * + * Copyright (C) 2017 Samsung Electronics Co., Ltd. + * Copyright (C) 2021 Linaro Ltd. + * + * Samsung's Exynos850 SoC pin-mux and pin-config options are listed as device + * tree nodes in this file. + */ + +#include +#include + +&pinctrl_alive { + gpa0: gpa0 { + gpio-controller;
