But I'm afraid I don't understand the purpose of this. Alternatively if you had made below additions depends on QCOM_THERMAL this would have "cleaned up" the menuconfig slightly. But IMHO there isn't a lot of benefit to this (and we'd end up with people running without thermal drivers, as they forget to set CONFIG_QCOM_THERMAL). > + tristate "Thermal drivers on Qualcomm Snapdragon series of SoCs" > + help > + Support for thermal drivers on Qualcomm Snapdragon series of SoCs. > + There are several thermal sensors available on the Qualcomm Socs > + which can be used for thermal mitigation purposes.

Introduce CONFIG_QCOM_THERMAL to allow better control over selection of various Qualcomm Thermal drivers available inside qcom/ directory. This is a preparatory change to allow new drivers to be added inside qcom/ directory in a more structured fashion later-on.
