This work improves Exynos thermal driver in various ways. This is
related to the discussion in
https://lore.kernel.org/all/[e-mail]/

The primary issue being fixed is a lockdep warning, which is fixed by
the thermal: exynos: use set_trips patch. We also simplify the code in
general.

Changelog:
 v5:
   - Used BIT wherever possible
   - Simplified Exynos 7 code and used the correct register offsets for
     Exynos 7
   - Refactored some common register-setting code
 v4:
   - Resolved merge conflict when applying thermal: exynos: split
     initialization of TMU and the thermal zone
   - Reordered calls done when leaving exynos_tmu_initialize for
     symmetry
 v3:
   - Fixed regulator initialization
   - Fixed formatting of some comments
 v2:
   - Added missing field descriptions
   - Removed an unnecessary field description
   - Removed the commits that made clock management more fine-grained
     (need more discussion), and adapted the new code to manage clocks
   - Removed the devicetree changes (will be uploaded separately),
     changing the recipient list accordingly
   - Improved formatting of the devm_request_threaded_irq call

Mateusz Majewski (9):
  thermal: exynos: remove an unnecessary field description
  thermal: exynos: drop id field
  thermal: exynos: switch from workqueue-driven interrupt handling to
    threaded interrupts
  thermal: exynos: handle devm_regulator_get_optional return value
    correctly
  thermal: exynos: simplify regulator (de)initialization
  thermal: exynos: stop using the threshold mechanism on Exynos 4210
  thermal: exynos: split initialization of TMU and the thermal zone
  thermal: exynos: use BIT wherever possible
  thermal: exynos: use set_trips
