title: RaspberryPi RP1 clock generator

maintainers:
  - A. della Porta <andrea.porta@suse.com>

description: |
  The RP1 contains a clock generator designed as three PLLs (CORE, AUDIO,
  VIDEO), and each PLL output can be programmed through dividers to generate
  the clocks to drive the sub-peripherals embedded inside the chipset.
