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.

I'm not in copy of the clocksource patch but I acked it for the initial
post.

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 [email protected] 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.

Hi,
Thank you for your comments.

I see.
I do my best to make it.

OK, I'll add the patches with "Acked" or "Reviewed" tag.

Okay, try to address them.
I send the next version as soon as possible.
