From: kongxinwei <kong.kongxinwei@xxxxxxxxxxxxx> The Linaro connect introduce 96boards series in Hong Kong,The HiKey board is the first board to be certified 96Boards Consumer Edition compatible. This board is based on the HiSilicon SoC. you can get more information from https://www.96boards.org. The hisilicon SoC contains thermal module, this thermal module has 4 sensors, - sensor 0: local sensor; - sensor 1: remote sensor for ACPU cluster 1; - sensor 2: remote sensor for ACPU cluster 2; - sensor 3: remote sensor for GPU; It can obtain this device temperature by operating this hardware. The new sensor driver satisfies thermal framework and to realize the ACPU ,GPU and so on to cool function. Changes v4->v5; * Rebase to kernel 4.1-rc1 * Add the DTS file according to the maintainer advice * Clean up "include" header file and fix detail format * Deal with negative temperature and add mutex lock to protect binding irq variable * Remove this "const struct themal_trip" from "struct hisi_thermal_sensor", making it as local variable * Make sensor_temp part of "struct hisi_thremal_sensors" Changes v3->v4; * using "usleep_range" function instead of "msleep" function * delete code detail error Changes v2->v3; * delete sensor id property in binding document * fix sensor driver to satisfy sensor register after deleting sensor id property Changes v1->v2; * change patch's position between binding document and driver file * clean up some regiser for enabling thermal sensor * use mutex lock to replace the spin lock Changes v0->v1; * Delete this hi6220 dtsi. * Fix documentation and error checks. * Modify this driver which makes use of kernel to decide how to dynamically bind the interrupt to hottest sensor. * Delete "sensor-thres-temp" property and read thermal_zone trips points replace of it. * Delete "sensor-reset-temp" property and define the fixed value replace of it. kongxinwei (3): dt-bindings: Document the hi6220 thermal sensor bindings thermal: hisilicon: add new hisilicon thermal sensor driver dts: hi6220: enable thermal sensor for hisilicon SoC .../bindings/thermal/hisilicon-thermal.txt | 23 ++ arch/arm64/boot/dts/hisilicon/hi6220.dtsi | 127 +++++++ drivers/thermal/Kconfig | 8 + drivers/thermal/Makefile | 1 + drivers/thermal/hisi_thermal.c | 418 +++++++++++++++++++++ 5 files changed, 577 insertions(+) create mode 100644 Documentation/devicetree/bindings/thermal/hisilicon-thermal.txt create mode 100644 arch/arm64/boot/dts/hisilicon/hi6220.dtsi create mode 100644 drivers/thermal/hisi_thermal.c -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
