  3This binding uses the common clock binding:
  4Documentation/devicetree/bindings/clock/clock-bindings.txt
  5
  6The Nomadik SRC controller is responsible of controlling chrystals,
  7PLLs and clock gates.

  9Required properties for the SRC node:
 10- compatible: must be "stericsson,nomadik-src"
 11- reg: must contain the SRC register base and size
 12
 13Optional properties for the SRC node:
 14- disable-sxtalo: if present this will disable the SXTALO
 15  i.e. the driver output for the slow 32kHz chrystal, if the
 16  board has its own circuitry for providing this oscillator
 17- disable-mxtal: if present this will disable the MXTALO,
 18  i.e. the driver output for the main (~19.2 MHz) chrystal,
 19  if the board has its own circuitry for providing this
 20  oscillator
 21
 22
 23PLL nodes: these nodes represent the two PLLs on the system,
 24which should both have the main chrystal, represented as a
 25fixed frequency clock, as parent.
 26
 27Required properties for the two PLL nodes:
 28- compatible: must be "st,nomadik-pll-clock"
 29- clock-cells: must be 0
 30- clock-id: must be 1 or 2 for PLL1 and PLL2 respectively
 31- clocks: this clock will have main chrystal as parent
 32
 33
 34HCLK nodes: these represent the clock gates on individual
 35lines from the HCLK clock tree and the gate for individual
 36lines from the PCLK clock tree.
 37
 38Requires properties for the HCLK nodes:
 39- compatible: must be "st,nomadik-hclk-clock"
 40- clock-cells: must be 0
 41- clock-id: must be the clock ID from 0 to 63 according to
