It is almost completely undocumented, so it was missed when doing the initial SoC bringup. This series adds the clock/reset, pin configuration, and device tree node needed to use the RSB controller. Since RSB is faster, simpler, and generally more reliable than the I2C controller IP in the SoC, switch to using it where possible. This was tested on an Orange Pi 3 and a Pine H64 model B. This series does not switch the Pine H64 to use RSB, as doing so would prevent accessing the external RTC that shares the I2C bus.
