thermal: intel: int340x: Add DLVR support for RFIM control

2023-04-18T13:24:40+00:00

Add support for DLVR (Digital Linear Voltage Regulator) attributes, which can be used to control RFIM. Here instead of "fivr" another directory "dlvr" is created with DLVR attributes: /sys/bus/pci/devices/0000:00:04.0/dlvr ├── dlvr_freq_mhz ├── dlvr_freq_select ├── dlvr_hardware_rev ├── dlvr_pll_busy ├── dlvr_rfim_enable └── dlvr_spread_spectrum_pct └── dlvr_control_mode └── dlvr_control_lock Attributes dlvr_freq_mhz (RO): Current DLVR PLL frequency in MHz. dlvr_freq_select (RW): Sets DLVR PLL clock frequency. dlvr_hardware_rev (RO): DLVR hardware revision. dlvr_pll_busy (RO): PLL can't accept frequency change when set. dlvr_rfim_enable (RW): 0: Disable RF frequency hopping, 1: Enable RF frequency hopping. dlvr_control_mode (RW): Specifies how frequencies are spread. 0: Down spread, 1: Spread in Center. dlvr_control_lock (RW): 1: future writes are ignored. dlvr_spread_spectrum_pct (RW) A write to this register updates the DLVR spread spectrum percent value.

thermal/core: Remove thermal_bind_params structure

2023-04-07T09:18:22+00:00

Remove struct thermal_bind_params because no one is using it for thermal binding now. Signed-off-by: Zhang Rui Signed-off-by: Daniel Lezcano Link: https://lore.kernel.org/r/20230330104526.3196-1-rui.zhang@intel.com

thermal: intel: int340x: Add production mode attribute

2023-01-26T13:47:16+00:00

It is possible that the system manufacturer locks down thermal tuning beyond what is usually done on the given platform. In that case user space calibration tools should not try to adjust the thermal configuration of the system. To allow user space to check if that is the case, add a new sysfs attribute "production_mode" that will be present when the ACPI DCFG method is present under the INT3400 device object in the ACPI Namespace.

docs: driver-api/thermal/intel_dptf: Use copyright symbol

2022-04-05T15:46:06+00:00

Using a substitution pattern of "|copy|" without including isonum.txt causes a doc build warning. Using the symbol "©" itself is a better choice for those who read .rst sources.

thermal: Move ABI documentation to Documentation/ABI

2021-10-07T17:25:47+00:00

The thermal ABI and the internal development details are described in: Documentation/driver-api/thermal/sysfs-api.rst Move the sysfs ABI description to Documentation/ABI, ensuring that scripts/get_abi.pl will properly parse it. While here, also update the thermal record in MAINTAINERS to point to the documentation.

thermal: Use generic HW-protection shutdown API

2021-06-21T12:08:37+00:00

The hardware shutdown function was exported from kernel/reboot for other subsystems to use. Logic is copied from the thermal_core. The protection mutex is replaced by an atomic_t to allow calls also from an IRQ context. Also the WARN() was replaced by pr_emerg() based on discussions here: https://lore.kernel.org/lkml/YJuPwAZroVZ%2Fw633@alley/ and here: https://lore.kernel.org/linux-iommu/20210331093104.383705-4-geert+renesas@glider.be/ Use the exported API instead of implementing own just for the thermal_core.
