This work improves Exynos thermal driver in various ways. This is
related to the discussion in
https://lore.kernel.org/all/97201878-3bb8-eac5-7fac-a690322ac43a@linaro.org/

The primary issue being fixed is a lockdep warning, which is fixed by
the thermal: exynos: use set_trips patch. We also handle Exynos 4210 not
supporting falling temperature thresholds by enabling polling for this
SoC, and simplify the code in general.

Mateusz Majewski (11):
  ARM: dts: exynos: enable polling in Exynos 4210
  thermal: exynos: drop id field
  thermal: exynos: switch from workqueue-driven interrupt handling to
    threaded interrupts
  thermal: exynos: remove fine-grained clk management
  thermal: exynos: simplify sclk (de)initialization
  thermal: exynos: simplify regulator (de)initialization
  thermal: exynos: simplify clk_sec (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 set_trips
  ARM: dts: exynos: disable polling in Odroid XU3-related devices
