ACPI: scan: substitute empty_zero_page with helper ZERO_PAGE(0)
Not all zero page implementations use empty_zero_page global pointer so let's substitute empty_zero_page occurence with helper ZERO_PAGE(0). Signed-off-by: Giulio Benetti <giulio.benetti@benettiengineering.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> |

ACPI: scan: Add LATT2021 to acpi_ignore_dep_ids[]
Some x86/ACPI laptops with MIPI cameras have a LATT2021 ACPI device in the _DEP dependency list of the ACPI devices for the camera-sensors (which have flags.honor_deps set). The _DDN for the LATT2021 device is "Lattice FW Update Client Driver", suggesting that this is used for firmware updates of something. There is no Linux driver for this and if Linux gets support for updates it will likely be in userspace through fwupd. For now add the LATT2021 HID to acpi_ignore_dep_ids[] so that acpi_dev_ready_for_enumeration() will return true once the other _DEP dependencies are met.

ACPI: scan: Fix DMA range assignment
Assigning the device's dma_range_map from the iterator variable after
the loop means it always points to the empty terminator at the end of
the map, which is not what we want. Similarly, freeing the iterator on
error when it points to somwhere in the middle of the allocated array
won't work either. Fix this.

ACPI: scan: Support multiple DMA windows with different offsets
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().

ACPI: Drop parent field from struct acpi_device
The parent field in struct acpi_device is, in fact, redundant, because the dev.parent field in it effectively points to the same object and it is used by the driver core. Accordingly, the parent field can be dropped from struct acpi_device and for this purpose define acpi_dev_parent() to retrieve a parent struct acpi_device pointer from the dev.parent field in struct acpi_device. Next, update all of the users of the parent field in struct acpi_device to use acpi_dev_parent() instead of it and drop it. While at it, drop the ACPI_IS_ROOT_DEVICE() macro that is only used in one place in a confusing way. No intentional functional impact. Signed-off-by: Rafael J.

ACPI: scan: Eliminate __acpi_device_add()
Instead of having acpi_device_add() defined as a wrapper around __acpi_device_add(), export acpi_tie_acpi_dev() so it can be called directly by acpi_add_power_resource(), fold acpi_device_add() into the latter and rename __acpi_device_add() to acpi_device_add().

ACPI: scan: Rearrange initialization of ACPI device objects
The initialization of ACPI device objects is split between acpi_init_device_object() and __acpi_device_add() that initializes the dev field in struct acpi_device. The "release" function pointer is passed to __acpi_device_add() for this reason. However, that split is artificial and all of the initialization can be carried out by acpi_init_device_object(), so rearrange the code to that end. In particular, make acpi_init_device_object() take the "release" pointer as an argument, along with the "type" which is related to it, instead of __acpi_device_add(). No intentional functional impact. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Reviewed-by: Punit Agrawal <punit.agrawal@bytedance.com> |

ACPI: Rename acpi_bus_get/put_acpi_device()
Because acpi_bus_get_acpi_device() is completely analogous to acpi_fetch_acpi_dev(), rename it to acpi_get_acpi_dev() and add a kerneldoc comment to it. Accordingly, rename acpi_bus_put_acpi_device() to acpi_put_acpi_dev() and update all of the users of these two functions. While at it, move the acpi_fetch_acpi_dev() header next to the acpi_get_acpi_dev() header in the header file holding them. Signed-off-by: Rafael J.

sound updates for 6.0-rc1
As diffstat shows, we've had lots of developments in a wide range at this time; the majority of changes are about ASoC, including subsystem-wide cleanups, continued SOF / Intel updates and a bunch of new drivers (as usual), while there have been some significant (but almost invisible) improvements in ALSA core side, too. Below are some highlights: Core: - Faster lookups of control elements with Xarray; normal user won't notice, but on the devices with tons of control elements, it can be visibly faster - Support for input validation for controls; this will harden for badly written drivers in general with a slight overhead - Deferred async signal handling for working around the potential deadlocks - Cleanup / refactoring raw MIDI locking code ASoC: - Restructing of the set_fmt() callbacks for making things clearer in situations like CODEC to CODEC links - Clean up and modernizing the DAI naming scheme setups - Merge of more of the Intel AVS driver stack, including some board integrations - New version 4 mechanism for communication with SOF DSPs - Suppoort for dynamically selecting the PLL to use at runtime on i.MX platforms - Improvements for CODEC to CODEC support in the generic cards - Support for AMD Jadeite and various machines, AMD RPL, Intel MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and WAS883x, and Texas Instruments TAS2780 HD- and USB-audio: - Continued improvement for CS35L41 (sub)codec support - More quirks for various devices (HP, Lenovo, Dell, Clevo) -----BEGIN PGP SIGNATURE----- iQJCBAABCAAsFiEEIXTw5fNLNI7mMiVaLtJE4w1nLE8FAmLr5bcOHHRpd2FpQHN1 c2UuZGUACgkQLtJE4w1nLE93IQ/+OleeiGv7C487QN5MrBCkdFnSAiXsXDArcMgo Gt6XLubH54et1tqi2ms4gRQOqr4HiBelERuqmaCLMZfEgVDc0VhJnf2jjhluYq9+ o9+kcYKul6qTZeNZLPjEX8pBvDe7HzOl7yep++ZnKeH6DAKNQQLDjVuOcQU/BXdY kL8vYrLI3zfqj/pCePb5xpkBx4XdCrE3TfiCr3tAHVg9MyvSGOJyWs02mEBqQRnc rlLmkjQVQyln/AGK4RAPMmrrFytktAvBjmIDyFL7kAzhdxe0ouNzTvdxESeojNJv CVo/p3hl/+0LYjpD2x9v2pQuifOfpjwSCy6f8jsaF366sMwR1D45h051prILsxAF 05D5AOwMCnnJdFQFxw3mIkoDva3/PRX8GFfHsXoz+efc5Ibp8ksNYVgAJ3D2TTtt 7nAYMn0dimVDtw2LHiKantgWAs/rOqD3hDzGxFj2sR662ahsHr8pT8csnJAGoBvW 7kgx7ZzFo/wSyZJqVqV7p4g6J79ScehRwhqoiwZau9Eo+PhuxZUKvm4RwGFh0Vvg GbiVRPfLV4xQd/pDin6qRX1M7cgPc62qGLkhQHAzrX6H5ipwIbQrpyDGLjwdSEp8 XcQmzCG1zGOvb9A8BY1VBOQXxZRTqN58XujbZ6hsms7Uw8sqagxpYLA/e1bvt1E1 RQoHQRw= =1n0/ -----END PGP SIGNATURE----- Merge tag 'sound-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "As the diffstat shows, we've had lots of developments in a wide range at this time; the majority of changes are about ASoC, including subsystem-wide cleanups, continued SOF / Intel updates and a bunch of new drivers (as usual), while there have been some significant (but almost invisible) improvements in ALSA core side, too.

ACPI: scan: Walk ACPI device's children using driver core
Instead of walking the list of children of an ACPI device directly, use acpi_dev_for_each_child() or acpi_dev_for_each_child_reverse() to carry out an action for all of the given ACPI device's children. This will help to eliminate the children list head from struct acpi_device as it is redundant and it is used in questionable ways in some places (in particular, locking is needed for walking the list pointed to it safely, but it is often missing).

sound updates for 5.18
It's been a fairly calm development cycle. There are a few last-minute ALSA core fixes, most notably for covering PCM ioctl races, but the most of rest are device-specific changes.

Input: soc_button_array - add support for Microsoft Surface 3 (MSHW0028) buttons
The drivers/platform/surface/surface3_button.c code is alsmost a 1:1 copy of the soc_button_array code. The only big difference is that it binds to an i2c_client rather then to a platform_device. The cause of this is the ACPI resources for the MSHW0028 device containing a bogus I2cSerialBusV2 resource which causes the kernel to instantiate an i2c_client for it instead of a platform_device. Add "MSHW0028" to the ignore_serial_bus_ids[] list in drivers/apci/scan.c, so that a platform_device will be instantiated and add support for the MSHW0028 HID to soc_button_array. This fully replaces surface3_button, which will be removed in a separate commit (since it binds to the now no longer created i2c_client it no longer does anyyhing after this commit). Note the MSHW0028 id is used by Microsoft to describe the tablet buttons on both the Surface 3 and the Surface 3 Pro and the actual API/implementation for the Surface 3 Pro is quite different. The changes in this commit should not impact the separate surfacepro3_button driver: 1. Because of the bogus I2cSerialBusV2 resource problem that driver binds to the acpi_device itself, so instantiating a platform_device instead of an i2c_client does not matter. 2. The soc_button_array driver will not bind to the MSHW0028 device on the Surface 3 Pro, because it has no GPIO resources.

ACPI: scan: Use ida_alloc() instead of ida_simple_get()
As recommended in include/linux/idr.h, use ida_alloc() instead of ida_simple_get() for creating unique device object names and for symmetry replace ida_simple_remove() with ida_free() (and fix up the related overly long code line while at it). Also drop the ACPI_MAX_DEVICE_INSTANCES limit that is not necessary any more and may not be sufficient for future platforms. Signed-off-by: Rafael J.

ACPI / scan: Create platform device for CS35L41
The ACPI device with CSC3551 or CLSA0100 are sound cards with multiple instances of CS35L41 connected by I2C or SPI to the main CPU. We add an ID to the ignore_serial_bus_ids list to enumerate all I2C or SPI devices correctly. The same IDs are also added into serial-multi-instantiate so that the driver can correctly enumerate the ACPI.

ACPI: scan: Simplify initialization of power and sleep buttons
It should be perfectly fine to use ACPI if the "fixed" power or sleep buttons cannot be initialized. Moreover, running acpi_bus_scan() successfully on ACPI_ROOT_OBJECT generally causes many devices to be enumerated and probed, possibly including the entire PCI bus, so unregistering acpi_root if the registration of the "fixed" buttons fails is rather unhelpful. For this reason, do not fail acpi_scan_init() when acpi_bus_scan_fixed() fails and turn the latter into a void function. While at it, drop the outdated and misleading comment from acpi_bus_scan_fixed(). Signed-off-by: Rafael J.

ACPI: scan: Change acpi_scan_init() return value type to void
The only caller of acpi_scan_init(), acpi_init(), doesn't check its return value, so turn it into a void function. This avoids complaints from the Smatch static checker that the function should return a negative error code when it fails, which is not really a problem in this particular case.

ACPI: scan: Create platform device for BCM4752 and LNV4752 ACPI nodes
BCM4752 and LNV4752 ACPI nodes describe a Broadcom 4752 GPS module
attached to an UART of the system.
The GPS modules talk a custom protocol which only works with a closed-
source Android gpsd daemon which knows this protocol.
The ACPI nodes also describe GPIOs to turn the GPS on/off these are
handled by the net/rfkill/rfkill-gpio.c code. This handling predates the
addition of enumeration of ACPI instantiated serdevs to the kernel and
was broken by that addition, because the ACPI scan code now no longer
instantiates platform_device-s for these nodes.
Rename the i2c_multi_instantiate_ids HID list to ignore_serial_bus_ids
and add the BCM4752 and LNV4752 HIDs, so that rfkill-gpio gets
a platform_device to bind to again; and so that a tty cdev for gpsd
gets created for these.

acpi: Store CRC-32 hash of the _PLD in struct acpi_device
Storing CRC-32 hash of the Physical Location of Device object (_PLD) with devices that have it. The hash is stored to a new struct acpi_device member "pld_crc". The hash makes it easier to find devices that share a location, as there is no need to evaluate the entire object every time. Knowledge about devices that share a location can be used in device drivers that need to know the connections to other components inside a system. USB3 ports will for example always share their location with a USB2 port. Acked-by: Rafael J.

ACPI: delay enumeration of devices with a _DEP pointing to an INT3472 device
The clk and regulator frameworks expect clk/regulator consumer-devices to have info about the consumed clks/regulators described in the device's fw_node. To work around cases where this info is not present in the firmware tables, which is often the case on x86/ACPI devices, both frameworks allow the provider-driver to attach info about consumers to the clks/regulators when registering these. This causes problems with the probe ordering wrt drivers for consumers of these clks/regulators. Since the lookups are only registered when the provider-driver binds, trying to get these clks/regulators before then results in a -ENOENT error for clks and a dummy regulator for regulators. One case where we hit this issue is camera sensors such as e.g. the OV8865 sensor found on the Microsoft Surface Go. The sensor uses clks, regulators and GPIOs provided by a TPS68470 PMIC which is described in an INT3472 ACPI device. There is special platform code handling this and setting platform_data with the necessary consumer info on the MFD cells instantiated for the PMIC under: drivers/platform/x86/intel/int3472. For this to work properly the ov8865 driver must not bind to the I2C-client for the OV8865 sensor until after the TPS68470 PMIC gpio, regulator and clk MFD cells have all been fully setup. The OV8865 on the Microsoft Surface Go is just one example, all X86 devices using the Intel IPU3 camera block found on recent Intel SoCs have similar issues where there is an INT3472 HID ACPI-device, which describes the clks and regulators, and the driver for this INT3472 device must be fully initialized before the sensor driver (any sensor driver) binds for things to work properly. On these devices the ACPI nodes describing the sensors all have a _DEP dependency on the matching INT3472 ACPI device (there is one per sensor). This allows solving the probe-ordering problem by delaying the enumeration (instantiation of the I2C-client in the ov8865 example) of ACPI-devices which have a _DEP dependency on an INT3472 device. The new acpi_dev_ready_for_enumeration() helper used for this is also exported because for devices, which have the enumeration_by_parent flag set, the parent-driver will do its own scan of child ACPI devices and it will try to enumerate those during its probe(). Code doing this such as e.g. the i2c-core-acpi.c code must call this new helper to ensure that it too delays the enumeration until all the _DEP dependencies are met on devices which have the new honor_deps flag set.

hwmon: (acpi_power_meter) Use acpi_bus_get_acpi_device()
In read_domain_devices(), acpi_bus_get_device() is called to obtain the ACPI device object attached to the given ACPI handle and subsequently that object is passed to get_device() for reference counting, but there is a window between the acpi_bus_get_device() and get_device() calls in which the ACPI device object in question may go away. To address this issue, make read_domain_devices() use acpi_bus_get_acpi_device() to reference count and return the given ACPI device object in one go and export that function to modules. While at it, also make read_domain_devices() and remove_domain_devices() use acpi_dev_put() instead of calling put_device() directly on the ACPI device objects returned by acpi_bus_get_acpi_device().

ACPI: scan: Release PM resources blocked by unused objects
On some systems the ACPI namespace contains device objects that are not used in certain configurations of the system. If they start off in the D0 power state configuration, they will stay in it until the system reboots, because of the lack of any mechanism possibly causing their configuration to change. If that happens, they may prevent some power resources from being turned off or generally they may prevent the platform from getting into the deepest low-power states thus causing some energy to be wasted. Address this issue by changing the configuration of unused ACPI device objects to the D3cold power state one after carrying out the ACPI-based enumeration of devices.

ACPI: Add driver for the VIOT table
The ACPI Virtual I/O Translation Table describes topology of para-virtual platforms, similarly to vendor tables DMAR, IVRS and IORT. For now it describes the relation between virtio-iommu and the endpoints it manages. Three steps are needed to configure DMA of endpoints: (1) acpi_viot_init(): parse the VIOT table, find or create the fwnode associated to each vIOMMU device. This needs to happen after acpi_scan_init(), because it relies on the struct device and their fwnode to be available. (2) When probing the vIOMMU device, the driver registers its IOMMU ops within the IOMMU subsystem. This step doesn't require any intervention from the VIOT driver. (3) viot_iommu_configure(): before binding the endpoint to a driver, find the associated IOMMU ops. Register them, along with the endpoint ID, into the device's iommu_fwspec. If step (3) happens before step (2), it is deferred until the IOMMU is initialized, then retried.

ACPI: Move IOMMU setup code out of IORT
Extract the code that sets up the IOMMU infrastructure from IORT, since it can be reused by VIOT. Move it one level up into a new acpi_iommu_configure_id() function, which calls the IORT parsing function which in turn calls the acpi_iommu_fwspec_init() helper.

ACPI: arm64: Move DMA setup operations out of IORT
Extract generic DMA setup code out of IORT, so it can be reused by VIOT. Keep it in drivers/acpi/arm64 for now, since it could break x86 platforms that haven't run this code so far, if they have invalid tables.
