* Thermal Monitoring Unit (TMU) on Freescale QorIQ SoCs
|
|
|
|
|
|
|
|
Required properties:
|
|
|
|
- compatible : Must include "fsl,qoriq-tmu". The version of the device is
|
|
|
|
determined by the TMU IP Block Revision Register (IPBRR0) at
|
|
|
|
offset 0x0BF8.
|
|
|
|
Table of correspondences between IPBRR0 values and example chips:

|
|
|
|
- reg : Address range of TMU registers.
|
|
|
|
- interrupts : Contains the interrupt for TMU.
|
|
|
|
- fsl,tmu-range : The values to be programmed into TTRnCR, as specified by
|
|
|
|
the SoC reference manual. The first cell is TTR0CR, the second is
|
|
|
|
TTR1CR, etc.
|
|
|
|
- fsl,tmu-calibration : A list of cell pairs containing temperature
|
|
|
|
calibration data, as specified by the SoC reference manual.
|
|
|
|
The first cell of each pair is the value to be written to TTCFGR,
|
|
|
|
and the second is the value to be written to TSCFGR.

|
|
|
- #thermal-sensor-cells : Must be 1. The sensor specifier is the monitoring
|
|
|
|
site ID, and represents the "n" in TRITSRn and TRATSRn.
|
|
|
|
|
|
|
|
Optional property:
|
|
|
|
- little-endian : If present, the TMU registers are little endian. If absent,
|
|
|
|
the default is big endian.
