Everyone:

This series contains patches adding support for HWMON integration, bug
fixes and general improvements (hopefully) for TMU driver I made while
working on it on i.MX8MQ.

Feedback is welcome!

Thanks,
Andrey Smirnov

Changes since [v4]

    - Collected Tested-by from Lucas
    
    - Collected Reviewed-by from Daniel

    - Converted "thermal: qoriq: Enable all sensors before registering
      them" to use if instead of switch statement for error checking

Changes since [v3]

    - Series reabse on top of [rfc]
    
    - Fixed incorrect goto label in "thermal: qoriq: Pass data to
      qoriq_tmu_calibration()"
      
    - Added REGS_TRITSR() register description to "thermal: qoriq: Do
      not report invalid temperature reading"
      
    - Reworded commit message of "thermal: qoriq: Remove unnecessary
      DT node is NULL check"

Changes since [v2]

    - Patches rebased on v5.1-rc1

Changes since [v1]

    - Rebased on "linus" branch of
      git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal.git
      that included latest chagnes adding multi-sensors support

    - Dropped

	thermal: qoriq: Add support for multiple thremal sites
	thermal: qoriq: Be more strict when parsing
	thermal: qoriq: Simplify error handling in qoriq_tmu_get_sensor_id()

      since they are no longer relevant

    - Added

	thermal: qoriq: Don't store struct thermal_zone_device reference
	thermal: qoriq: Add local struct qoriq_sensor pointer
	thermal: qoriq: Embed per-sensor data into struct qoriq_tmu_data
	thermal: qoriq: Pass data to qoriq_tmu_register_tmu_zone() directly

      to simplify latest codebase

    - Changed "thermal: qoriq: Do not report invalid temperature
      reading" to use regmap_read_poll_timeout() to make sure that
      tmu_get_temp() waits for fist sample to be ready before
      reporting it. This case is triggered on my setup if
      qoriq_thermal is compiled as a module
