The bcm2835 SOC contains an auxiliary uart, which is very close to the ns16550 with some differences. The big difference is that the uart HW is not using an internal divider of 16 but 8, which results in an effictive baud-rate being twice the requested baud-rate. This driver handles this device correctly and handles the difference in the HW divider by scaling up the clock by a factor of 2. The approach to write a separate (wrapper) driver instead of using a multiplying clock and "ns16550" as compatibility in the device-tree has been recommended by Stephen Warren.
