[PATCH v8 6/9] thermal/drivers/exynos: Refactor SoC-specific configuration to new exynos_tmu_soc_config structure
From: Anand Moon
Date: Sat Feb 14 2026 - 13:21:32 EST
Move SoC-specific parameters and function pointers from exynos_tmu_data
to a new exynos_tmu_soc_config structure.
Instead of manually assigning values in exynos_map_dt_data() using a
switch-case block, define static configuration structures for each
supported SoC and retrieve them via of_device_get_match_data().
This refactoring:
- Reduces the complexity of the mapping function.
- Makes the driver more extensible for future SoCs.
- Cleanly separates static hardware descriptions from runtime state.
Signed-off-by: Anand Moon <linux.amoon@xxxxxxxxx>

v8: New patch, With this refactoring of SoC callbacks it will simpilfy
for new SoC to be integrated.
