All new code paths have been tested on a exynosautov920 board and verified to correctly read temperatures and emulate behavior. Changes in v4: - Kept 'addtionalProperties: false'. - Removed the 'samsung,hw-sensor-indices' property in the binding. - Added the 'samsung,sensors' property in the binding. - Dropped code-like formatting and rewrote the description in plain, hardware-focused language in the commit message. - Removed the bitmap and replaced the tz_count to sensor_count. Changes in v3: - Removed redundant commit message. - Rephrased the sentences to describe the hardware clearly. - Restricted sensor indices to V920. - Set #thermal-sensor-cells per variant. - Replaced 'additionalProperties' with 'unevaluatedProperties'. - Removed the duplicate #define and use the original. - Used lowercase hex in #define. - Simplified 'temp_to_code' and 'code_to_temp' to one computation path by normalizing calib_temp. Changes in v2: - Replace the generic property with a vendor-specific one. - Added an indices property instead of ranges. - Shortened thermal node name and made them more generic. - Updated the indices logic accordingly after removing the ranges property.
