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 simplify the code in general. Changelog: 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 (8): 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 set_trips drivers/thermal/samsung/exynos_tmu.c | 538 ++++++++++++++------------- 1 file changed, 283 insertions(+), 255 deletions(-)
