2020-07-24hwmon: (corsair-cpro) add reading pwm valuesMarius Zachmann1-4/+3
This adds the possibility for reading pwm values. These can not be read if the device is controlled via fan_target or a fan curve and will return an error in this case. Since an error is expected, this adds some rudimentary error handling. Changes: - add CTL_GET_FAN_PWM and use it via get_data - pwm returns -ENODATA if the device returns error 0x12 - fan_target now returns -ENODATA when the driver is started or a pwm value is set. - add ccp_get_errno to determine errno from device error. - get_data now has a parameter to determine whether to read one or two bytes of data. - update documentation - fix missing surname in MAINTAINERS Signed-off-by: Marius Zachmann <mail@mariuszachmann.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2020-07-24hwmon: add Corsair Commander Pro driverMarius Zachmann2-0/+43
This is v7 of a driver for the Corsair Commander Pro. It provides sysfs attributes for: - Reading fan speed - Reading temp sensors - Reading voltage values - Writing pwm and reading last written pwm - Reading fan and temp connection status It is an usb driver, so it needs to be ignored by usbhid. The Corsair Commander Pro is a fan controller and provides no means for user interaction. The two device numbers are there, because there is a slightly different version of the same device. (Only difference seem to be in some presets.) Squashed: hwmon: (corsair-cpro) add fan_target This adds fan_target entries to the corsair-cpro driver. Reading the attribute from the device does not seem possible, so it returns the last set value (same as pwm). send_usb_cmd now has one more argument, which is needed for the fan_target command. hwmon: corsair-cpro: Change to HID driver This changes corsair-cpro to a hid driver using hid reports.

2020-05-28hwmon: Add Baikal-T1 PVT sensor driverSerge Semin2-0/+118
Baikal-T1 SoC provides an embedded process, voltage and temperature sensor to monitor an internal SoC environment (chip temperature, supply voltage and process monitor) and on time detect critical situations, which may cause the system instability and even damages. The IP-block is based on the Analog Bits PVT sensor, but is equipped with a dedicated control wrapper, which provides a MMIO registers-based access to the sensor core functionality (APB3-bus based) and exposes an additional functions like thresholds/data ready interrupts, its status and masks, measurements timeout. All of these is used to create a hwmon driver being added to the kernel by this commit. The driver implements support for the hardware monitoring capabilities of Baikal-T1 process, voltage and temperature sensors. PVT IP-core consists of one temperature and four voltage sensors, each of which is implemented as a dedicated hwmon channel config. The driver can optionally provide the hwmon alarms for each sensor the PVT controller supports. The alarms functionality is made compile-time configurable due to the hardware interface implementation peculiarity, which is connected with an ability to convert data from only one sensor at a time. Additional limitation is that the controller performs the thresholds checking synchronously with the data conversion procedure. Due to these limitations in order to have the hwmon alarms automatically detected the driver code must switch from one sensor to another, read converted data and manually check the threshold status bits. Depending on the measurements timeout settings this design may cause additional burden on the system performance. By default if the alarms kernel config is disabled the data conversion is performed by the driver on demand when read operation is requested via corresponding _input-file.

2020-03-08hwmon: (pmbus) Implement multi-phase supportGuenter Roeck1-2/+6
Some PMBus chips support multiple phases, and report telemetry such as input current, output current, or temperature for each phase. Add support for such chips to the PMBus core. Start with a maximum of 8 phases per page, and assume that supported sensors per phase are similar for all pages. Only support per-phase telemetry attributes, no limits or alarms. As part of this patch, set the initial page variable to 0xff to ensure that the page is updated when the first page command is issued. Also only issue page commands if the chip supports more than one page. Cc: Vadim Pasternak <vadimp@mellanox.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2020-01-23hwmon: Driver for disk and solid state drives with temperature sensorsGuenter Roeck2-0/+53
Reading the temperature of ATA drives has been supported for years by userspace tools such as smarttools or hddtemp. The downside of such tools is that they need to run with super-user privilege, that the temperatures are not reported by standard tools such as 'sensors' or 'libsensors', and that drive temperatures are not available for use in the kernel's thermal subsystem. This driver solves this problem by adding support for reading the temperature of ATA drives from the kernel using the hwmon API and by adding a temperature zone for each drive. With this driver, the hard disk temperature can be read using the unprivileged 'sensors' application: $ sensors drivetemp-scsi-1-0 drivetemp-scsi-1-0 Adapter: SCSI adapter temp1: +23.0°C or directly from sysfs: $ grep . /sys/class/hwmon/hwmon9/{name,temp1_input} /sys/class/hwmon/hwmon9/name:drivetemp /sys/class/hwmon/hwmon9/temp1_input:23000 If the drive supports SCT transport and reports temperature limits, those are reported as well. drivetemp-scsi-0-0 Adapter: SCSI adapter temp1: +27.0°C (low = +0.0°C, high = +60.0°C) (crit low = -41.0°C, crit = +85.0°C) (lowest = +23.0°C, highest = +34.0°C) The driver attempts to use SCT Command Transport to read the drive temperature. If the SCT Command Transport feature set is not available, or if it does not report the drive temperature, drive temperatures may be readable through SMART attributes. Since SMART attributes are not well defined, this method is only used as fallback mechanism. Cc: Chris Healy <cphealy@gmail.com> Cc: Linus Walleij <linus.walleij@linaro.org> Cc: Martin K.

Now we just need to get maintainers to fill in the profiles... - A reworking of the parallel build setup to work better with a variety of systems (and to not take over huge systems entirely in particular). - The MAINTAINERS file is now converted to RST during the build. Hopefully nobody ever tries to print this thing, or they will need to load a lot of paper. - A script and documentation making it easy for maintainers to add Link: tags at commit time.
