ST Microelectronics Nomadik SRC System Reset and Control
This binding uses the common clock binding:
Documentation/devicetree/bindings/clock/clock-bindings.txt
The Nomadik SRC controller is responsible of controlling chrystals,
PLLs and clock gates.
Required properties for the SRC node:
- compatible: must be "stericsson,nomadik-src"
- reg: must contain the SRC register base and size
Optional properties for the SRC node:
- disable-sxtalo: if present this will disable the SXTALO
i.e. the driver output for the slow 32kHz chrystal, if the
board has its own circuitry for providing this oscillator
- disable-mxtal: if present this will disable the MXTALO,
i.e. the driver output for the main (~19.2 MHz) chrystal,
if the board has its own circuitry for providing this
oscillator
PLL nodes: these nodes represent the two PLLs on the system,
which should both have the main chrystal, represented as a
fixed frequency clock, as parent.
Required properties for the two PLL nodes:
- compatible: must be "st,nomadik-pll-clock"
- clock-cells: must be 0
- clock-id: must be 1 or 2 for PLL1 and PLL2 respectively
- clocks: this clock will have main chrystal as parent
HCLK nodes: these represent the clock gates on individual
lines from the HCLK clock tree and the gate for individual
lines from the PCLK clock tree.
Requires properties for the HCLK nodes:
- compatible: must be "st,nomadik-hclk-clock"
- clock-cells: must be 0
- clock-id: must be the clock ID from 0 to 63 according to
