Summary

As part of the Icecube PVT bring-up process, new SMB (System Main Board) units have been manufactured with version combination 3.1.10 (Production State: 3, Version: 1, Sub-version: 10).

This PR adds the necessary sensor configuration block in sensor_service.json to support these new units. Without this change, the sensor_service would fail to correctly associate and monitor the voltage rails for this specific hardware revision.

The update specifically includes VOUT monitoring for the four SMB TRVDD rails (Phase 0-3), mapped to in4_input on their respective voltage monitor chips:

• SMB_XP0R72V_PB_TRVDD_0_VOUT -> SMB_ASIC_VOLTAGE_0
• SMB_XP0R72V_PB_TRVDD_1_VOUT -> SMB_ASIC_VOLTAGE_6
• SMB_XP0R72V_PB_TRVDD_2_VOUT -> SMB_ASIC_VOLTAGE_3
• SMB_XP0R72V_PB_TRVDD_3_VOUT -> SMB_ASIC_VOLTAGE_7

Test Plan

1. Syntax Validation: Validated JSON syntax.

2. Formatting: Pretty-printed configurations using the jq command for readability.

3. Build & Config Tests: Compilation and configuration validation tests passed successfully.

4. Service Verification: Confirmed that the following services start and run without errors:

   • platform_manager
   • sensor_service/sensor_service_client/sensor_service_sw_test/sensor_service_hw_test

5. Hardware Identification: Verified the SMB version (3.1.10) is correctly identified via FRU/EEPROM utility during initial bring-up.

6. Voltage Audit: Confirmed TRVDD voltage readings are within the nominal 0.72V range (verified via sensor_service_client).
