2022-09-25hwmon: (vt8231) Reorder symbols to get rid of a few forward declarationsUwe Kleine-König
Declarations for static symbols are useless repetition unless there are cyclic dependencies. Reorder the functions and variables to get rid of 5 forward declarations.

2022-09-25hwmon: (vt8231) Introduce a #define for the driver name and use itUwe Kleine-König
Make use of the cpp symbol DRIVER_NAME to set the driver's name and use it instead of all explicit usages of the same string. Also make use of it instead of vt8231_driver.driver.name which breaks a cyclic dependency between vt8231_probe() and vt8231_driver that in the next commit allows to drop some forward declarations.

2022-09-25hwmon: (pwm-fan) Switch regulator dynamicallyAlexander Stein
This adds the enable attribute which is used to select if zero PWM duty means to switch off regulator and PWM or to keep them enabled but at inactive PWM output level. Depending on the select enable mode, turn off the regulator and PWM if the PWM duty is zero, or keep them enabled. This is especially important for fan using inverted PWM signal polarity. Having regulator supplied and PWM disabled, some PWM controllers provide the active, rather than inactive signal. With this change the shutdown as well as suspend/resume paths require modifcations as well.

2022-09-24Merge branch 'for-6.0/dax' into libnvdimm-fixesDan Williams
Pick up another "Soft Reservation" fix for v6.0-final on top of some straggling nvdimm fixes that missed v5.19.
2022-09-24devdax: Fix soft-reservation memory descriptionDan Williams
The "hmem" platform-devices that are created to represent the platform-advertised "Soft Reserved" memory ranges end up inserting a resource that causes the iomem_resource tree to look like this: 340000000-43fffffff : hmem.0 340000000-43fffffff : Soft Reserved 340000000-43fffffff : dax0.0 This is because insert_resource() reparents ranges when they completely intersect an existing range. This matters because code that uses region_intersects() to scan for a given IORES_DESC will only check that top-level 'hmem.0' resource and not the 'Soft Reserved' descendant. So, to support EINJ (via einj_error_inject()) to inject errors into memory hosted by a dax-device, be sure to describe the memory as IORES_DESC_SOFT_RESERVED. This is a follow-on to: commit b13a3e5fd40b ("ACPI: APEI: Fix _EINJ vs EFI_MEMORY_SP") ...that fixed EINJ support for "Soft Reserved" ranges in the first instance.

2022-09-24ACPI: fan: Reorder symbols to get rid of a few forward declarationsUwe Kleine-König
Having the driver struct at the end of the file isn't only more usual, it also allows to drop a few forward declarations which are just useless repetition. While at it also move the MODULE_... macros to the end of the file. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
2022-09-24ACPI: CPPC: Disable FIE if registers in PCC regionsJeremy Linton
PCC regions utilize a mailbox to set/retrieve register values used by the CPPC code. This is fine as long as the operations are infrequent. With the FIE code enabled though the overhead can range from 2-11% of system CPU overhead (ex: as measured by top) on Arm based machines. So, before enabling FIE assure none of the registers used by cppc_get_perf_ctrs() are in the PCC region. Finally, add a module parameter which can override the PCC region detection at boot or module reload.

2022-09-24LoongArch: Use acpi_arch_dma_setup() and remove ARCH_HAS_PHYS_TO_DMAJianmin Lv
Use _DMA defined in ACPI spec for translation between DMA address and CPU address, and implement acpi_arch_dma_setup for initializing dev->dma_range_map, where acpi_dma_get_range is called for parsing _DMA. e.g. If we have two dma ranges: cpu address dma address size offset 0x200080000000 0x2080000000 0x400000000 0x1fe000000000 0x400080000000 0x4080000000 0x400000000 0x3fc000000000 _DMA for pci devices should be declared in host bridge as flowing: Name (_DMA, ResourceTemplate() { QWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, NonCacheable, ReadWrite, 0x0, 0x4080000000, 0x447fffffff, 0x3fc000000000, 0x400000000, , , ) QWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, NonCacheable, ReadWrite, 0x0, 0x2080000000, 0x247fffffff, 0x1fe000000000, 0x400000000, , , ) }) Acked-by: Huacai Chen <chenhuacai@loongson.cn> Signed-off-by: Jianmin Lv <lvjianmin@loongson.cn> Signed-off-by: Rafael J.

2022-09-24ACPI: scan: Support multiple DMA windows with different offsetsJianmin Lv
In DT systems configurations, of_dma_get_range() returns struct bus_dma_region DMA regions; they are used to set-up devices DMA windows with different offset available for translation between DMA address and CPU address. In ACPI systems configuration, acpi_dma_get_range() does not return DMA regions yet and that precludes setting up the dev->dma_range_map pointer and therefore DMA regions with multiple offsets. Update acpi_dma_get_range() to return struct bus_dma_region DMA regions like of_dma_get_range() does. After updating acpi_dma_get_range(), acpi_arch_dma_setup() is changed for ARM64, where the original dma_addr and size are removed as these arguments are now redundant, and pass 0 and U64_MAX for dma_base and size of arch_setup_dma_ops; this is a simplification consistent with what other ACPI architectures also pass to iommu_setup_dma_ops().

2022-09-24ACPI: x86: Add a quirk for Dell Inspiron 14 2-in-1 for StorageD3EnableMario Limonciello
Dell Inspiron 14 2-in-1 has two ACPI nodes under GPP1 both with _ADR of 0, both without _HID. It's ambiguous which the kernel should take, but it seems to take "DEV0". Unfortunately "DEV0" is missing the device property `StorageD3Enable` which is present on "NVME". To avoid this causing problems for suspend, add a quirk for this system to behave like `StorageD3Enable` property was found.
