thermal/drivers/qcom: Drop false build dependency of all QCOM drivers on QCOM_TSENS

2022-10-04T09:21:11+00:00

The SPMI QCOM drivers have no dependency in Kconfig, but the Makefile will not be included without QCOM_TSENS. This unnecessarily reduces build coverage.

thermal: k3_j72xx_bandgap: Add the bandgap driver support

2022-05-19T10:11:53+00:00

Add VTM thermal support. In the Voltage Thermal Management Module(VTM), K3 J72XX supplies a voltage reference and a temperature sensor feature that are gathered in the band gap voltage and temperature sensor (VBGAPTS) module. The band gap provides current and voltage reference for its internal circuits and other analog IP blocks. The analog-to-digital converter (ADC) produces an output value that is proportional to the silicon temperature. Currently reading temperatures only is supported. There are no active/passive cooling agent supported. J721e SoCs have errata i2128: https://www.ti.com/lit/pdf/sprz455 The VTM Temperature Monitors (TEMPSENSORs) are trimmed during production, with the resulting values stored in software-readable registers. Software should use these register values when translating the Temperature Monitor output codes to temperature values. It has an involved workaround. Software needs to read the error codes for -40C, 30C, 125C from the efuse for each device & derive a new look up table for adc to temperature conversion. Involved calculating slopes & constants using 3 different straight line equations with adc refernce codes as the y-axis & error codes in the x-axis. -40C to 30C 30C to 125C 125C to 150C With the above 2 line equations we derive the full look-up table to workaround the errata i2128 for j721e SoC. Tested temperature reading on J721e SoC & J7200 SoC.

thermal/drivers: Add TSU driver for RZ/G2L

2021-11-30T16:27:56+00:00

The RZ/G2L SoC incorporates a thermal sensor unit (TSU) that measures the temperature inside the LSI. The thermal sensor in this unit measures temperatures in the range from −40 degree Celsius to 125 degree Celsius with an accuracy of ±3°C. The TSU repeats measurement at 20 microseconds intervals and automatically updates the results of measurement. The TSU has no interrupts as well as no external pins. This patch adds Thermal Sensor Unit(TSU) driver for RZ/G2L SoC.

thermal: netlink: Fix compilation error when CONFIG_NET=n

2020-07-21T08:39:17+00:00

When the network is not configured, the netlink is disabled on all the system. The thermal framework assumed the netlink is always opt-in. Fix this by adding a Kconfig option for the netlink notification, defaulting to yes and depending on CONFIG_NET. As the change implies multiple stubs and in order to not pollute the internal thermal header, the thermal_nelink.h has been added and included in the thermal_core.h, so this one regain some kind of clarity.

thermal: core: genetlink support for events/cmd/sampling

2020-07-07T13:55:21+00:00

Initially the thermal framework had a very simple notification mechanism to send generic netlink messages to the userspace. The notification function was never called from anywhere and the corresponding dead code was removed. It was probably a first attempt to introduce the netlink notification. At LPC2018, the presentation "Linux thermal: User kernel interface", proposed to create the notifications to the userspace via a kfifo. The advantage of the kfifo is the performance. It is usually used from a 1:1 communication channel where a driver captures data and sends it as fast as possible to a userspace process. The drawback is that only one process uses the notification channel exclusively, thus no other process is allowed to use the channel to get temperature or notifications. This patch defines a generic netlink API to discover the current thermal setup and adds event notifications as well as temperature sampling. As any genetlink protocol, it can evolve and the versioning allows to keep the backward compatibility. In order to prevent the user from getting flooded with data on a single channel, there are two multicast channels, one for the temperature sampling when the thermal zone is updated and another one for the events, so the user can get the events only without the thermal zone temperature sampling. Also, a list of commands to discover the thermal setup is added and can be extended when needed.
