Subject: [PATCH v8 4/9] thermal/drivers/exynos: Fixed the efuse min max value for exynos5422
Date: Sat, 14 Feb 2026 23:49:01 +0530	[thread overview]
Message-ID: <20260214181930.238981-5-linux.amoon@gmail.com> (raw)
In-Reply-To: <20260214181930.238981-1-linux.amoon@gmail.com>

As per Exynos5422 user manual e-Fuse range min~max range is 16~76.
if e-Fuse value is out of this range, then thermal sensor may not
sense thermal data properly. Additionally, refactors the efuse
initialization logic in exynos_map_dt_data() by replacing nested
if-else blocks with a switch statement for better readability
and maintainability. Ensures correct efuse setup based on SoC type.

Signed-off-by: Anand Moon <linux.amoon@gmail.com>

v8: None
v7: drop the Rb Llukasz, as we dropped the nested switch to set efuse.
v6: Add Rb Lukasz and fix typo in subject
v5: None
V4: None
