Is there a maximum number?

That's a uint32-matrix, not an array:

minItmes: ??
maxItems: ??
items:
  items:
    - description: value for TTCFGR

No need to redefine common properties.

-Required properties:
-- compatible : Must include "fsl,qoriq-tmu" or "fsl,imx8mq-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:
-		Value           Device
-		----------      -----
-		0x01900102      T1040
-- 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.
-- clocks : the clock for clocking the TMU silicon.
