CCS PLL calculator
==================
The CCS PLL calculator is used to compute the PLL configuration, given sensor's
capabilities as well as board configuration and user specified configuration. As
the configuration space that encompasses all these configurations is vast, the
PLL calculator isn't entirely trivial. Yet it is relatively simple to use for a
driver.
The PLL model implemented by the PLL calculator corresponds to MIPI CCS 1.1.
