[PATCH v3] thermal: amlogic: add missing dependency on MESON_SM

[sashiko-bot at kernel.org]

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [High] The commit introduces a spurious `depends on MESON_SM` dependency for `CONFIG_AMLOGIC_THERMAL` based on the false premise that the driver calls `meson_sm_get()` and `meson_sm_get_thermal_calib()`. An analysis of `drivers/thermal/amlogic_thermal.c` confirms it relies on a syscon regmap (`amlogic,ao-secure`) for its calibration data and makes no calls to the secure monitor driver. Crucially, `MESON_SM` strictly depends on `ARM64_4K_PAGES`. Thus, this patch inadvertently disables thermal management on all Amlogic systems using 16K or 64K page sizes, or those intentionally omitting `MESON_SM`.

thermal: amlogic: add missing dependency on MESON_SM

This commit adds a dependency on MESON_SM to the Amlogic thermal driver
configuration to address reported undefined references.

[Severity: High]
The commit message states that the amlogic thermal driver calls
meson_sm_get() and meson_sm_get_thermal_calib(). Is this description
accurate?

Looking at drivers/thermal/amlogic_thermal.c, the driver appears to rely on a
syscon regmap (amlogic,ao-secure) for its calibration data, rather than making
direct calls to the secure monitor.

Since MESON_SM has a strict dependency on ARM64_4K_PAGES, wouldn't adding
this dependency inadvertently disable thermal management on all Amlogic
systems using 16K or 64K page sizes, or those intentionally omitting MESON_SM?

Without thermal management, these systems might suffer from a lack of
active cooling or thermal throttling.
