Several Qualcomm Snapdragon SoCs have Thermal Mitigation Devices (TMDs) present on various remote subsystem(s) (for e.g. the Compute DSP, aka cDSP), which can be used for several mitigations for remote subsystem(s), including remote processor mitigation, rail voltage restriction etc. Here we introduce the Qualcomm Cooling Driver which is based on the kernel thermal driver framework and also employs the kernel QMI interface to send the message to remote subsystem(s). At the very top-level, the dts is supposed to describe a TMD node, which should further represent the remote subsystem(s) present on the SoC and further each child of a subsystem should represent the separate cooling devices available on the remote subsystem. Note that this patchset is targeted for the 'linux-pm' tree and the dts patchset/changes targeted for 'linux-arm-msm' tree will be sent as a separate patchset. This patchset is based on the CONFIG_QCOM_THERMAL related fix sent via [1]. Otherwise the latest changes from 'linux-next/master' are used to rebase the patchset.
