2024-10-10clk: samsung: exynosautov920: add peric1, misc and hsi0/1 clock supportSunyeal Hong
Register compatible and cmu_info data to support clocks. CMU_PERIC1, this provides clocks for USI09 ~ USI17, USI_I2C and USI_I3C. CMU_MISC, this provides clocks for MISC, GIC and OTP. CMU_HSI0, this provides clocks for PCIE. CMU_HSI1, this provides clocks for USB and MMC.

Samsung clock controller fixes for v6.12 Add missing sentinel in of_device_id table, so the code iterating over it will not go over the size of an array. Further code depends on the fixes branch.

2024-10-09dt-bindings: clock: xilinx: describe whether dynamic reconfig is enabledHarry Austen
Xilinx clocking wizard IP core's dynamic reconfiguration support is optionally enabled at build time. Add a devicetree boolean property to describe whether the hardware supports this feature or not. Since dynamic reconfiguration support was previously assumed enabled, introduce a property to indicate the inverse, in order to maintain devicetree backwards compatibility. Hence, this new xlnx,static-config property should be specified when dynamic reconfiguration support is disabled in the IP core configuration.

Some PLLS with fractional multipliers have fractional denominators with fixed values, instead of the previous "(1 << pll-> frc.width)".

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.
