2024-10-31mfd: axp20x: Add support for AXP323Andre Przywara
The X-Powers AXP323 is a very close sibling of the AXP313A. The only difference seems to be the ability to dual-phase the first two DC/DC converter, which adds another register. Add the required boilerplate to introduce a new PMIC to the AXP MFD driver. Where possible, this just maps into the existing structs defined for the AXP313A, only deviating where needed.

2024-10-31mfd: axp20x: Ensure relationship between IDs and model namesAndre Przywara
At the moment there is an implicit relationship between the AXP model IDs and the order of the strings in the axp20x_model_names[] array. This is fragile, and makes adding IDs in the middle error prone. Make this relationship official by changing the ID type to the actual enum used, and using indexed initialisers for the string list.

2024-10-31dt-bindings: mfd: x-powers,axp152: Document AXP323Andre Przywara
The X-Powers AXP323 is a PMIC used on some newer Allwinner devices. It is almost the same as the AXP313, but supports dual-phasing the first two DC/DC converters. A pure AXP313 driver wouldn't know about this, and might turn the linked DCDC2 regulator off, as it does not seem to be used. This makes the AXP323 incompatible to the AXP313a. Add the new compatible string, and treat it like the AXP313a.

2024-10-16mfd: bd96801: Add ERRB IRQMatti Vaittinen
The ROHM BD96801 "scalable PMIC" provides two physical IRQs. The ERRB handling can in many cases be omitted because it is used to inform fatal IRQs, which usually kill the power from the SOC. There may however be use-cases where the SOC has a 'back-up' emergency power source which allows some very short time of operation to try to gracefully shut down sensitive hardware. Furthermore, it is possible the processor controlling the PMIC is not powered by the PMIC. In such cases handling the ERRB IRQs may be beneficial. Add support for ERRB IRQs.

2024-10-16mfd: syscon: Use regmap max_register_is_0 as neededNishanth Menon
syscon has always set the optional max_register configuration of regmap to ensure the correct checks are in place. However, a recent commit 0ec74ad3c157 ("regmap: rework ->max_register handling") introduced explicit configuration in regmap framework for register maps that is exactly 1 register, when max_register is pointing to a valid register 0. This commit solved a previous limitation of regmap framework. Update syscon driver to consistent in regmap configuration for all sizes of syscons by using this new capability by setting max_register_is_0, when the max_register is valid and 0.

2024-10-16dt-bindings: mfd: mediatek: mt6397: Convert to DT schema formatMacpaul Lin
Convert the mfd: mediatek: mt6397 binding to DT schema format. MT6323, MT6358, and MT6397 are PMIC devices with multiple function subdevices. They share a common PMIC design but have variations in subdevice combinations. Key updates in this conversion: 1. RTC: - Convert rtc-mt6397.txt and merge into parent MT6397 PMIC DT schema. 2. Regulators: - Align to generic name "regulators". - Update references from .txt to .yaml for mt6323, mt6358, and mt6397 regulators. - Simplify regulator name labels in device tree examples. 3. Audio Codec: - Simplify Audio Codec part with updating compatible items. - Align to generic name "audio-codec" for codec and sound subdevices. 4. Clocks: - Align to generic name "clocks" for clockbuffer subdevices. 5. LEDs: - Convert leds-mt6323.txt and merge into parent MT6397 PMIC DT schema. - Update LED binding. 6. Keys: - Add detailed descriptions for power and home keys. - Add compatible: mediatek,mt6358-keys. 7. Power Controller: - Convert mt6323-poweroff.txt and merge into parent MT6397 PMIC DT schema. - Add #power-domain-cells property to fix dt-binding check error. - Clarify "BBPU" as "Baseband power up". 8. Pinctrl: - Align to generic name "pinctrl" instead of "pin-controller". 9. Compatible: - Drop "mediatek,mt6357" since there is a separated DT Schema for PMIC MT6357. 10. Examples: - MT6323: Retain complete examples for this PMIC. - MT6358 and MT6397: simplify settings in regulators. - Preserve "audio-codec", "clocks", "pinctrl", "rtc", and "keys" sections as they contain typical settings for different PMICs. Additional updates: - MAINTAINERS: Add co-maintainers and reference to mfd/mediatek,mt6397.yaml for LED and power-controller drivers. - input/mediatek,pmic-keys.yaml: Update reference to mfd/mediatek,mt6397.yaml.

2024-09-29x86: kvm: fix build errorLinus Torvalds
The cpu_emergency_register_virt_callback() function is used unconditionally by the x86 kvm code, but it is declared (and defined) conditionally: #if IS_ENABLED(CONFIG_KVM_INTEL) || IS_ENABLED(CONFIG_KVM_AMD) void cpu_emergency_register_virt_callback(cpu_emergency_virt_cb *callback); ... leading to a build error when neither KVM_INTEL nor KVM_AMD support is enabled: arch/x86/kvm/x86.c: In function ‘kvm_arch_enable_virtualization’: arch/x86/kvm/x86.c:12517:9: error: implicit declaration of function ‘cpu_emergency_register_virt_callback’ [-Wimplicit-function-declaration] 12517 | cpu_emergency_register_virt_callback(kvm_x86_ops.emergency_disable_virtualization_cpu); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ arch/x86/kvm/x86.c: In function ‘kvm_arch_disable_virtualization’: arch/x86/kvm/x86.c:12522:9: error: implicit declaration of function ‘cpu_emergency_unregister_virt_callback’ [-Wimplicit-function-declaration] 12522 | cpu_emergency_unregister_virt_callback(kvm_x86_ops.emergency_disable_virtualization_cpu); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Fix the build by defining empty helper functions the same way the old cpu_emergency_disable_virtualization() function was dealt with for the same situation. Maybe we could instead have made the call sites conditional, since the callers (kvm_arch_{en,dis}able_virtualization()) have an empty weak fallback. I'll leave that to the kvm people to argue about, this at least gets the build going for that particular config.
