Hi, This series adds support for SCPI based sensors for ARM development platform. In addition to supporting sensors, when a temperature sensor is discovered the driver registers the sensor with the thermal framework.
The sensor patches here have been split out from a longer series adding support for registering power model based cooling devices for the CPU via device tree. Earliers postings can be seen at [0], [1], [2]. Patches 1-3 create a hwmon sensor driver for sensors provided by SCPI firmware. Patch 4 adds support for the temperature sensors to register with the thermal framework. This allows setting up platform thermals using OF thermal bindings. The last patch adds support for the sensors in the Juno r0 device tree. The patches depend on SCPI and mailbox patches[3] from Sudeep. The SCPI protocol document with details of the sensor interface can be found at [4]. I'd like to aim for merging the patches with the SCPI changes if possible. The hwmon patches have been acked by Guenter. If there aren't any objections, I would like to request acks for the binding updates in Patch 1. Thanks, Punit Changes v3 -> v4 - clarified binding regarding use of sensor identifier Changes v2 -> v3 - split out the sensor patches (posted here) - rebase onto v4.3-rc1 Changes v1 -> v2 - added documentation for the scpi-hwmon driver - replaced static allocation of platform structure in scpi-hwmon.c with dynamic allocation - re-structured registering of thermal zones to better handle error conditions - reduced chattiness in scpi-hwmon.c - corrected sensor numbering to align with hwmon documentation - dynamic allocation of attributes and attribute groups [0] http://thread.gmane.org/gmane.linux.kernel/2002152 [1] http://thread.gmane.org/gmane.linux.kernel/2011466 [2] http://thread.gmane.org/gmane.linux.power-management.general/65475 [3] http://thread.gmane.org/gmane.linux.kernel/2009735 [4] http://infocenter.arm.com/help/topic/com.arm.doc.dui0922b/index.html Punit Agrawal (5): Documentation: add DT bindings for ARM SCPI sensors firmware: arm_scpi: Extend to support sensors hwmon: Support sensors exported via ARM SCP interface hwmon: Support thermal zones registration for SCP temperature sensors arm64: dts: Add sensor node to Juno dt Documentation/devicetree/bindings/arm/arm,scpi.txt | 38 +++ Documentation/hwmon/scpi-hwmon | 33 +++ arch/arm64/boot/dts/arm/juno-base.dtsi | 5 + drivers/firmware/arm_scpi.c | 60 +++++ drivers/hwmon/Kconfig | 8 + drivers/hwmon/Makefile | 1 + drivers/hwmon/scpi-hwmon.c | 288 +++++++++++++++++++++ include/linux/scpi_protocol.h | 17 ++ 8 files changed, 450 insertions(+) create mode 100644 Documentation/hwmon/scpi-hwmon create mode 100644 drivers/hwmon/scpi-hwmon.c -- 2.5.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
