The CDCE913 and CDCEL913 devices are modular PLL-based, low cost, high performance , programmable clock synthesizers. They generate upto 3 output clocks from a single input frequency. Each output can be programmed for any clock-frequency. Adding support for the same. Reviewed-by: Tom Rini <trini@konsulko.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
