> The IT8613E is not recognized by the in-tree it87 driver. Full
> support was proposed previously but withdrawn after problems were found
> in the temperature and PWM paths.
>
> Add conservative support limited to fan input monitoring. Detect device
> ID 0x8613, check the fan pin muxes, use the existing 16-bit tachometer
> layout, and expose enabled fan inputs read-only. Do not expose voltage,
> temperature, PWM, limit, beep, or alarm interfaces.
>
> The device ID and fan pin-mux checks follow the earlier v4 proposal by
> Benoit Masson.
>
> Tested on a system with an IT8613E at 0xa30, revision 12. Only
> fan2_input was exposed, with stable readings between 1268 and 1320 RPM.
> In a back-to-back comparison, the in-tree driver with force_id=0x8622
> reported 1483 RPM and the out-of-tree driver reported 1442 RPM.
