Thermal zones created via platform code or device tree can be set up to calculate their temperature as the maximum 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 adds device tree support and patch 3 exports the hierarchy to sysfs. Changes since v1: - Fix the prototype of thermal_zone_{add,del}_subtz() for !CONFIG_THERMAL as reported by the kbuild test robot Javi Merino (3): thermal: Add support for hierarchical thermal zones thermal: of: parse stacked thermal zones from device tree thermal: show the sub thermal zones in sysfs .../devicetree/bindings/thermal/thermal.txt | 154 +++++++++++++++++- Documentation/thermal/sysfs-api.txt | 40 +++++ drivers/thermal/of-thermal.c | 99 ++++++++++++ drivers/thermal/thermal_core.c | 173 ++++++++++++++++++++- include/linux/thermal.h | 17 ++ 5 files changed, 475 insertions(+), 8 deletions(-) -- 1.9.1
