ACPI: platform: Move SMB0001 HID to the header and reuse

2023-07-04T17:28:20+00:00

There are at least two places in the kernel that are using the SMB0001 HID. Make it to be available via acpi_drivers.h header file. While at it, replace hard coded one with a definition.

ACPI: platform: Ignore SMB0001 only when it has resources

2023-07-04T17:28:20+00:00

After switching i2c-scmi driver to be a platform one, it stopped being enumerated on number of Kontron platforms, because it's listed in the forbidden_id_list. To resolve the situation, add a flag to driver data to allow devices with no resources in _CRS to be enumerated via platform bus.

Merge branches 'acpi-scan', 'acpi-bus' and 'acpi-platform'

2022-09-30T18:28:22+00:00

Merge changes related to ACPI device enumeration and ACPI support for platform devices for 6.1-rc1: - Clean up ACPI platform devices support code (Andy Shevchenko, John Garry). - Clean up ACPI bus management code (Andy Shevchenko, ye xingchen). - Add support for multiple DMA windows with different offsets to the ACPI device enumeration code and use it on LoongArch (Jianmin Lv). * acpi-scan: LoongArch: Use acpi_arch_dma_setup() and remove ARCH_HAS_PHYS_TO_DMA ACPI: scan: Support multiple DMA windows with different offsets * acpi-bus: ACPI: bus: Refactor ACPI matching functions for better readability ACPI: bus: Drop kernel doc annotation from acpi_bus_notify() ACPI: bus: Remove the unneeded result variable * acpi-platform: ACPI: platform: Use PLATFORM_DEVID_NONE in acpi_create_platform_device() ACPI: platform: Sort forbidden_id_list[] in ascending order ACPI: platform: Use sizeof(*pointer) instead of sizeof(type) ACPI: platform: Remove redundant print on -ENOMEM ACPI: platform: Get rid of redundant 'else'

ACPI: platform: Use PLATFORM_DEVID_NONE in acpi_create_platform_device()

Instead of hardcoding the value for the id, use PLATFORM_DEVID_NONE. Signed-off-by: John Garry Reviewed-by: Andy Shevchenko Signed-off-by: Rafael J. Wysocki

ACPI: platform: Sort forbidden_id_list[] in ascending order

2022-09-03T18:53:17+00:00

For easier maintenance, sort the forbidden_id_list[] table rows in ascending order with respect to the device ID field. While at it, use an empty row as the list terminator, which is more usual in the kernel. Signed-off-by: Andy Shevchenko Signed-off-by: Rafael J. Wysocki

ACPI: platform: Use sizeof(*pointer) instead of sizeof(type)

2022-09-03T18:53:17+00:00

It is preferred to use sizeof(*pointer) instead of sizeof(type). The type of the variable can change and one needs not change the former (unlike the latter). No functional change intended. Signed-off-by: Andy Shevchenko Signed-off-by: Rafael J. Wysocki

ACPI: platform: Remove redundant print on -ENOMEM

2022-09-03T18:53:17+00:00

We rely on somebody else to print enough information on memory allocation failures. So remove the log in the acpi_create_platform_device() when return -ENOMEM. Signed-off-by: Andy Shevchenko Signed-off-by: Rafael J. Wysocki

ACPI: Drop parent field from struct acpi_device

2022-08-24T18:55:24+00:00

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.
