This series adds the ability to create a hierarchy of thermal zones. Thermal zones created via platform code or device tree can be set up to calculate their temperature as the maximum or weighted average of all its underlying thermal zones. This came up from discussions during LPC.
The first patch adds the basic support to thermal core. Patch 2 extends the devicetree bindings to cope with a hierarchy of thermal zones. Patch 3 adds device tree support. The last patch exports the hierarchy to sysfs, adding knobs to change the aggregation function and adjust the weights of thermal zones.
Changes since v2: - The aggregation function can be maximum or weighted average - Separated the update of the devicetree binding and the of-thermal into two separate patches
Javi Merino (4): thermal: Add support for hierarchical thermal zones devicetree: bindings: let thermal-sensor point to other thermal zones thermal: of: parse stacked thermal zones from device tree thermal: show the sub thermal zones in sysfs
