* [PATCH v2 00/15] Add basic support for Socionext Milbeaut M10V SoC @ 2019-02-08 12:24 Sugaya Taichi 2019-02-18 12:20 ` Arnd Bergmann 0 siblings, 1 reply; 4+ messages in thread From: Sugaya Taichi @ 2019-02-08 12:24 UTC (permalink / raw) To: devicetree, linux-kernel, linux-arm-kernel, linux-clk, linux-gpio, linux-serial Cc: Rob Herring, Mark Rutland, Michael Turquette, Stephen Boyd, Linus Walleij, Greg Kroah-Hartman, Daniel Lezcano, Thomas Gleixner, Russell King, Jiri Slaby, Takao Orito, Kazuhiro Kasai, Shinji Kanematsu, Jassi Brar, Masami Hiramatsu, Sugaya Taichi Hi, 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. Changes since v1: * Change file names. * Change #define names. * Refine cpu-enable-method and bindigs. * Add documentation for Milbeaut SoCs. * Add more infomation for timer driver. * Add sched_clock to timer driver. * Refine whole of clk driver. * Add earlycon instead of earlyprintk. * Refine Device Tree.

Support for the other peripherals will come eventually. I've looked over the platform once more. Overall, it looks very good, and I'd still like to merge this for linux-5.1, but we are running out of time there. If you send the patches to soc@kernel.org quickly, we can try to still merge them in, but if anything goes wrong, it will have to wait until we start merging patches for 5.2, directly after 5.1 is out. I did not look at the device driver patches (clk, clocksource, pinctrl, serial) in much detail. If you have an Ack from the maintainers, feel free to include them in the series, otherwise let's merge the rest now and then you can send the updated patches for inclusion through the subsystem trees in 5.2. I have sent a few comments. The only one that is really important here is the missing platform check in the suspend options. Please try to address most of the other commentsm, either by changing the code, or by explaining why your version is correct. Arnd ^ permalink raw reply [flat|nested] 4+ messages in thread
