This patch serises are to add timer driver for the StarFive JH7110
RISC-V SoC. The first patch adds documentation to describe device
tree bindings. The subsequent patch adds timer driver and support
JH7110 SoC. The last patch adds device node about timer to JH7110
dts.

This timer has four free-running 32 bit counters in StarFive JH7110
SoC. And each channel(counter) triggers an interrupt when timeout.
They support one-shot mode and continuous-run mode.

The last patch should be applied after the patchset [1]:

Changes since v1:
- Added description about timer and modified properties' description
  in dt-bindings.
- Dropped the 'interrupt-names' and 'clock-frequency' in dt-bindings.
- Renamed the functions and added 'starfive_'
- Modified that the driver probe by platform bus.
