Hi All,
This series performs a number of cleanups and refactoring changes to the
Samsung Exynos TMU driver.
The series starts with clock lifecycle and interrupt handling cleanups,
followed by improvements to triminfo clock handling and correction of
the Exynos5420 efuse trimming range.
The later patches simplify the TMU register mapping and refactor the
SoC-specific configuration into static variant data selected through
the device tree match table. Thermal zone operations are also moved
into the variant data, allowing the thermal zone registration to use
the SoC-specific configuration directly.
v8: Refactor SoC-specific configuration to new exynos_tmu_soc_config
structure which help clean up the callbacks.
dropped the IRQ clean up patches, with new approach
it will be much eaasy for new SoC to be integrated
and the code will be much better way managed in the future.
v7: Integrated my RFC patch which improves the IRQ framework
for all the SoC link below.
v6: Add new patch to use devm_clk_get_enabled
and Fix few typo in subject as suggested by Daniel.
v5: Drop the guard mutex patch
v4: Tried to address Lukasz review comments.
I dont have any Arm64 device the test and verify
Tested on 32 bit Arch Odroid U3 amd XU4 SoC boards.
Please share the feedback on this.
