thermal/drivers/imx91: Add support for i.MX91 thermal monitoring unit

2025-11-26T14:51:28Z

Introduce support for the i.MX91 thermal monitoring unit, which features a single sensor for the CPU. The register layout differs from other chips, necessitating the creation of a dedicated file for this. This sensor provides a resolution of 1/64°C (6-bit fraction). For actual accuracy, refer to the datasheet, as it varies depending on the chip grade. Provide an interrupt for end of measurement and threshold violation and Contain temperature threshold comparators, in normal and secure address space, with direction and threshold programmability.

powercap: intel_rapl: Prepare read_raw() interface for atomic-context callers

2025-11-21T20:47:08Z

The current read_raw() implementation of the TPMI, MMIO and MSR interfaces does not distinguish between atomic and non-atomic callers. rapl_msr_read_raw() uses rdmsrq_safe_on_cpu(), which can sleep and issue cross CPU calls. When MSR-based RAPL PMU support is enabled, PMU event handlers can invoke this function from atomic context where sleeping or rescheduling is not allowed. In atomic context, the caller is already executing on the target CPU, so a direct rdmsrq() is sufficient. To support such usage, introduce an atomic flag to the read_raw() interface to allow callers pass the context information. Modify the common RAPL code to propagate this flag, and set the flag to reflect the calling contexts. Utilize the atomic flag in rapl_msr_read_raw() to perform direct MSR read with rdmsrq() when running in atomic context, and a sanity check to ensure target CPU matches the current CPU for such use cases. The TPMI and MMIO implementations do not require special atomic handling, so the flag is ignored in those paths. This is a preparatory patch for adding MSR-based RAPL PMU support.

thermal/drivers/rcar_gen3: Convert to DEFINE_SIMPLE_DEV_PM_OPS()

2025-11-20T14:33:45Z

Convert the Renesas R-Car Gen3 thermal driver from SIMPLE_DEV_PM_OPS() to DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr(). This lets us drop the __maybe_unused annotation from its resume callback, and reduces kernel size in case CONFIG_PM or CONFIG_PM_SLEEP is disabled.

2025-11-12T20:14:21Z

Add support for DLVR (Digital Linear Voltage Regulator) for Nova Lake. There are no new sysfs attributes or difference in operations compared to prior generations. MMIO offset and bit positions are changed. Also no mapping is required as units are already in MHz.

2025-11-12T20:13:13Z

Replace sprintf() calls with sysfs_emit() in sysfs "show" functions to follow current kernel coding standards. sysfs_emit() is the preferred method for formatting sysfs output as it provides better bounds checking and is more secure.
