CAN Device Tree Bindings

------------------------
|

Flexcan CAN contoller on Freescale's ARM and PowerPC system-on-a-chip (SOC).
|
||||
|
||||
fsl,flexcan-v1.0 nodes
|
||||
-----------------------
|
||||
In addition to the required compatible-, reg- and interrupt-properties, you can
|
||||
also specify which clock source shall be used for the controller.
|
||||
Required properties:
|
||||
|
||||
CPI Clock- Can Protocol Interface Clock
|
||||
This CLK_SRC bit of CTRL(control register) selects the clock source to
|
||||
the CAN Protocol Interface(CPI) to be either the peripheral clock
|
||||
(driven by the PLL) or the crystal oscillator clock. The selected clock
|
||||
is the one fed to the prescaler to generate the Serial Clock (Sclock).
|
||||
The PRESDIV field of CTRL(control register) controls a prescaler that
|
||||
generates the Serial Clock (Sclock), whose period defines the
|
||||
time quantum used to compose the CAN waveform.
|
||||
- compatible : Should be "fsl,<processor>-flexcan"
|
||||
|
||||
Can Engine Clock Source
|
||||
There are two sources for CAN clock
|
||||
- Platform Clock It represents the bus clock
|
||||
- Oscillator Clock
|
||||
An implementation should also claim any of the following compatibles
|
||||
that it is fully backwards compatible with:
|
||||
|
||||
Peripheral Clock (PLL)

||||

- fsl,flexcan-clock-source : CAN Engine Clock Source.This property selects
|
||||
the peripheral clock. PLL clock is fed to the
|
||||
prescaler to generate the Serial Clock (Sclock).
|
||||
Valid values are "oscillator" and "platform"
|
||||
"oscillator": CAN engine clock source is oscillator clock.
|
||||
"platform" The CAN engine clock source is the bus clock
|
||||
(platform clock).
|
||||
- reg : Offset and length of the register set for this device
|
||||
- interrupts : Interrupt tuple for this device
|
||||
- clock-frequency : The oscillator frequency driving the flexcan device
|
||||
|
||||
- fsl,flexcan-clock-divider : for the reference and system clock, an additional
|
||||
clock divider can be specified.
|
||||
- clock-frequency: frequency required to calculate the bitrate for FlexCAN.
|
||||
Example:
|
||||
|
||||
Note:
|
||||
- v1.0 of flexcan-v1.0 represent the IP block version for P1010 SOC.
|
||||
- P1010 does not have oscillator as the Clock Source.So the default
|
||||
Clock Source is platform clock.
