Merge branch 'milbeaut/newsoc' into arm/newsoc (c889e2a0) · Commits · 戴 / test

Sugaya Taichi <sugaya.taichi@socionext.com> explains: Here is the series of patches the initial support for SC2000(M10V) of Milbeaut SoCs. "M10V" is the internal name of SC2000, so commonly used in source code. SC2000 is a SoC of the Milbeaut series. equipped with a DSP optimized for computer vision. It also features advanced functionalities such as 360-degree, real-time spherical stitching with multi cameras, image stabilization for without mechanical gimbals, and rolling shutter correction. More detail is below: https://www.socionext.com/en/products/assp/milbeaut/SC2000.html Specifications for developers are below: - Quad-core 32bit Cortex-A7 on ARMv7-A architecture - NEON support - DSP - GPU - MAX 3GB DDR3 - Cortex-M0 for power control - NAND Flash Interface - SD UHS-I - SD UHS-II - SDIO - USB2.0 HOST / Device - USB3.0 HOST / Device - PCI express Gen2 - Ethernet Engine - I2C - UART - SPI - PWM Support is quite minimal for now, since it only includes timer, clock, pictrl and serial controller drivers, so we can only boot to userspace through initramfs. Support for the other peripherals will come eventually. * milbeaut/newsoc: ARM: multi_v7_defconfig: add ARCH_MILBEAUT and ARCH_MILBEAUT_M10V ARM: configs: Add Milbeaut M10V defconfig ARM: dts: milbeaut: Add device tree set for the Milbeaut M10V board clocksource/drivers/timer-milbeaut: Introduce timer for Milbeaut SoCs dt-bindings: timer: Add Milbeaut M10V timer description ARM: milbeaut: Add basic support for Milbeaut m10v SoC dt-bindings: Add documentation for Milbeaut SoCs dt-bindings: arm: Add SMP enable-method for Milbeaut dt-bindings: sram: milbeaut: Add binding for Milbeaut smp-sram Link: https://lore.kernel.org/linux-arm-kernel/1551243056-10521-1-git-send-email-sugaya.taichi@socionext.com/ Signed-off-by:

		Milbeaut SRAM for smp bringup

		Milbeaut SoCs use a part of the sram for the bringup of the secondary cores.
		Once they get powered up in the bootloader, they stay at the specific part
		of the sram.
		Therefore the part needs to be added as the sub-node of mmio-sram.

		Required sub-node properties:
		- compatible : should be "socionext,milbeaut-smp-sram"

		Example:

		sram: sram@0 {
		compatible = "mmio-sram";
		reg = <0x0 0x10000>;
		#address-cells = <1>;
		#size-cells = <1>;
		ranges = <0 0x0 0x10000>;

		smp-sram@f100 {
		compatible = "socionext,milbeaut-smp-sram";
		reg = <0xf100 0x20>;
		};
		};

		Milbeaut SoCs Timer Controller

		Required properties:

		- compatible : should be "socionext,milbeaut-timer".
		- reg : Specifies base physical address and size of the registers.
		- interrupts : The interrupt of the first timer.
		- clocks: phandle to the input clk.

		Example:

		timer {
		compatible = "socionext,milbeaut-timer";
		reg = <0x1e000050 0x20>
		interrupts = <0 91 4>;
		clocks = <&clk 4>;
