| Message-ID | <rXtex-4cZ-9@gated-at.bofh.it> |
This patch set adds hardware temperature and power reading support for APM X-Gene SoC using the mailbox communication interface. For device tree, it is the standard DT mailbox. For ACPI, it is the PCC mailbox. For ACPI, this patch is built on top and depends on patch[1]: [1] http://www.spinics.net/lists/linux-acpi/msg66041.html - [PATCH v3] mailbox: pcc: Support HW-Reduced Communication Subspace type 2 v3 - Order include files alphabetically - Use sign_extend32() to decode temperature - Use DEVICE_ATTR_RO() for temperature and power attributes - Temperature and power attributes start with index 1 - Use !!amsg->param2 - Fix checkpatch WARNING with --strict flag - Use hwmon_device_register_with_groups() - Check invalid sensor data v2 - Increase power reading accurateness by using 2 registers (a register for Watt, another for milli-Watt) - Remove power reading for SoC - Fix review comments from Guenter v1 - Initial Hoan Tran (3): Documentation: dtb: xgene: Add hwmon dts binding documentation hwmon: xgene: Add hwmon driver arm64: dts: apm: Add X-Gene SoC hwmon to device tree .../devicetree/bindings/hwmon/apm-xgene-hwmon.txt | 14 + Documentation/hwmon/xgene-hwmon | 30 + arch/arm64/boot/dts/apm/apm-shadowcat.dtsi | 5 + arch/arm64/boot/dts/apm/apm-storm.dtsi | 5 + drivers/hwmon/Kconfig | 7 + drivers/hwmon/Makefile | 1 + drivers/hwmon/xgene-hwmon.c | 755 +++++++++++++++++++++ 7 files changed, 817 insertions(+) create mode 100644 Documentation/devicetree/bindings/hwmon/apm-xgene-hwmon.txt create mode 100644 Documentation/hwmon/xgene-hwmon create mode 100644 drivers/hwmon/xgene-hwmon.c -- 1.9.1

+APM X-Gene hwmon driver
+
+APM X-Gene SOC sensors are accessed over the "SLIMpro" mailbox.
+
+Required properties :
+ - compatible : should be "apm,xgene-slimpro-hwmon"
+ - mboxes : use the label reference for the mailbox as the first parameter.
+ The second parameter is the channel number.
+
+Example :
+ hwmonslimpro {
+ compatible = "apm,xgene-slimpro-hwmon";
+ mboxes = <&mailbox 7>;
+ };
