clocksource/drivers/clps711x: Remove board support

2019-03-24T10:30:11+00:00

Since board support for the CLPS711X platform was removed,
remove the board support from the clps711x-timer driver.

clocksource/drivers/riscv: Fix clocksource mask

2019-03-23T11:25:34+00:00

For all riscv architectures (RV32, RV64 and RV128), the clocksource
is a 64 bit incrementing counter.

Fix the clock source mask accordingly.

Tested on both 64bit and 32 bit virt machine in QEMU.

Pull ARM new SoC family support from Arnd Bergmann:
 "Two new SoC families are added this time.

  Sugaya Taichi submitted support for the Milbeaut SoC family from
  Socionext and explains:

    "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"

  Interestingly, this one has a history dating back to older chips made
  by Socionext and previously Matsushita/Panasonic based on their own
  mn10300 CPU architecture that was removed from the kernel last year.

  Manivannan Sadhasivam adds support for another SoC family, this is the
  Bitmain BM1880 chip used in the Sophon Edge TPU developer board.

  The chip is intended for Deep Learning applications, and comes with
  dual-core Arm Cortex-A53 to run Linux as well as a RISC-V
  microcontroller core to control the tensor unit. For the moment, the
  TPU is not accessible in mainline Linux, so we treat it as a generic
  Arm SoC.

clocksource/drivers/timer-milbeaut: Introduce timer for Milbeaut SoCs

2019-03-01T14:18:27+00:00

Add timer driver for Milbeaut SoCs series.

The timer has two 32-bit width down counters, one of which is configured
as a clockevent device and the other is configured as a clock source.
