Ryzen 7000 (Raphael) introduced AMDI0008 for _HID. This ID was added in commit ed470feb ("ACPI: PM: s2idle: Add support for upcoming AMD uPEP HID AMDI008"), but then removed in favor of aligning all new IDs to Rembrandt support in commit fd894f05 ("ACPI: x86: s2idle: If a new AMD _HID is missing assume Rembrandt"). Unfortunately there was a mistake in commit 100a5737 ("ACPI: x86: s2idle: Move _HID handling for AMD systems into structures") that can lead to a NULL pointer dereference accessing `dev_id->driver_data` in the sentinel of `amd_hid_ids`. Fix this dereference. Reported-by:

OEMs have made some mistakes in the past for the AMD GUID support and not populated the method properly. To add an escape hatch for this problem introduce a module parameter that can force using the Microsoft GUID. This is intentionally introduced to both Intel and AMD codepaths to allow using the parameter as a debugging tactic on either. Reviewed-by:

A mistake was made that only AMDI0007 was set to rev of "2", but it should have been also set for AMDI008. If an ID is missing from the _HID table, then assume it matches Rembrandt behavior. This implicitly means that if any other behavior changes happen in the future missing IDs must be added to that table. Tested-by: catalin@antebit.com Reviewed-by:

Currently, we only support passing a single gpiod_lookup_table as part of the board data for the tps68470 driver. This carries the implicit assumption that each TPS68470 device will only support a single sensor, which does not hold true. Extend the code to support the possibility of multiple sensors each having a gpiod_lookup_table, and opportunistically add the lookup table for the Surface Go line's IR camera. Reviewed-by:

At present, the tps68470.c only supports a single clock consumer when passing platform data to the clock driver. In some devices multiple sensors depend on the clock provided by a single TPS68470 and so all need to be able to acquire the clock. Support passing multiple consumers as platform data. Reviewed-by:

In commit b83e2b30 ("ACPI: scan: Add function to fetch dependent of ACPI device") we added a means of fetching the first device to declare itself dependent on another ACPI device in the _DEP method. One assumption in that patch was that there would only be a single consuming device, but this has not held. Replace that function with a new function that fetches the next consumer of a supplier device. Where no "previous" consumer is passed in, it behaves identically to the original function. Reviewed-by:

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. Signed-off-by:

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().

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".

The PCI device returned by acpi_get_pci_dev() needs to be registered, so if it corresponds to an ACPI device object, the struct acpi_device representing that object must be registered too and, moreover, it should be the ACPI companion of the given PCI device. Thus it should be sufficient to look for it in the ACPI device object's list of physical nodes associated with it. Modify the code accordingly. Signed-off-by:
