2016-12-09hwmon: Add Texas Instruments TMP108 temperature sensor driver.John Muir1-0/+36
Add support for the TI TMP108 temperature sensor with some device configuration parameters. Signed-off-by: John Muir <john@jmuir.com> [groeck: Initialize of_match_table] Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2016-12-09hwmon: (core) Rename groups parameter in API to extra_groupsGuenter Roeck1-11/+11
The 'groups' parameter of hwmon_device_register_with_info() and devm_hwmon_device_register_with_info() is only necessary if extra non-standard attributes need to be provided. Rename the parameter to extra_groups and clarify the documentation. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2016-12-09hwmon: (core) Deprecate hwmon_device_register()Guenter Roeck1-20/+14
Inform the user that hwmon_device_register() is deprecated, and suggest conversion to the newest API. Also remove hwmon_device_register() from the kernel API documentation. Note that hwmon_device_register() is not marked as __deprecated() since doing so might result in build errors. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2016-12-09hwmon: (core) Clarify use of chip attributesGuenter Roeck1-1/+1
Describing chip attributes as "attributes which apply to the entire chip" is confusing. Rephrase to "attributes which are not bound to a specific input or output". Also rename hwmon_chip_attr_templates[] to hwmon_chip_attrs[] to indicate that the respective strings strings are not templates but actual attribute names.

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC driver updates from Olof Johansson: "As we've enabled multiplatform kernels on ARM, and greatly done away with the contents under arch/arm/mach-*, there's still need for SoC-related drivers to go somewhere. Many of them go in through other driver trees, but we still have drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code that might be shared between ARM and ARM64 (or just in general makes sense to not have under the architecture directory). This branch contains mostly such code: - Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to communicate with power management blocks on these SoCs for use by clock, regulator and bus frequency drivers. - Allwinner Reduced Serial Bus driver, again used to communicate with PMICs. - Drivers for ARM's SCPI (System Control Processor). Not to be confused with PSCI (Power State Coordination Interface). SCPI is used to communicate with the assistant embedded cores doing power management, and we have yet to see how many of them will implement this for their hardware vs abstracting in other ways (or not at all like in the past). - To make confusion between SCPI and PSCI more likely, this release also includes an update of PSCI to interface version 1.0. - Rockchip support for power domains. - A driver to talk to the firmware on Raspberry Pi" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (57 commits) soc: qcom: smd-rpm: Correct size of outgoing message bus: sunxi-rsb: Add driver for Allwinner Reduced Serial Bus bus: sunxi-rsb: Add Allwinner Reduced Serial Bus (RSB) controller bindings ARM: bcm2835: add mutual inclusion protection drivers: psci: make PSCI 1.0 functions initialization version dependent dt-bindings: Correct paths in Rockchip power domains binding document soc: rockchip: power-domain: don't try to print the clock name in error case soc: qcom/smem: add HWSPINLOCK dependency clk: berlin: add cpuclk ARM: berlin: dts: add CLKID_CPU for BG2Q ARM: bcm2835: Add the Raspberry Pi firmware driver soc: qcom: smem: Move RPM message ram out of smem DT node soc: qcom: smd-rpm: Correct the active vs sleep state flagging soc: qcom: smd: delete unneeded of_node_put firmware: qcom-scm: build for correct architecture level soc: qcom: smd: Correct SMEM items for upper channels qcom-scm: add missing prototype for qcom_scm_is_available() qcom-scm: fix endianess issue in __qcom_scm_is_call_available soc: qcom: smd: Reject send of too big packets soc: qcom: smd: Handle big endian CPUs ...
