1ST Microelectronics Nomadik SRC System Reset and Control
2
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
