Mgerge remote-tracking branch 'torvalds/master' into perf/core
To sync headers, for instance, in this case tools/perf was ahead of upstream till Linus merged tip/perf/core to get the PERF_RECORD_TEXT_POKE changes: Warning: Kernel ABI header at 'tools/include/uapi/linux/perf_event.h' differs from latest version at 'include/uapi/linux/perf_event.h' diff -u tools/include/uapi/linux/perf_event.h include/uapi/linux/perf_event.h Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

-* Thermal Monitoring Unit (TMU) on Freescale QorIQ SoCs
-
-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.

-Example:
