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 [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

[v1] lore.kernel.org/lkml/[e-mail]

  thermal_hwmon: Add devres wrapper for thermal_add_hwmon_sysfs()
