ACPI: x86: Move LPSS to x86 folder

2024-04-08T14:39:24+00:00

LPSS is built solely for x86, move it to the respective folder. Signed-off-by: Andy Shevchenko Signed-off-by: Rafael J. Wysocki

ACPI: LPSS: Remove nested ifdeffery for CONFIG_PM

2024-04-08T14:36:51+00:00

There is no need to have the ifdef CONFIG_PM to be nested. The second and so on will obviously become a no-op. Remove redundant nested ifdeffery. Signed-off-by: Andy Shevchenko Reviewed-by: Kuppuswamy Sathyanarayanan Signed-off-by: Rafael J. Wysocki

Merge ACPI resources management quirks, ACPI NUMA updates, an ACPI LPSS (Intel SoC) driver update and an ACPI watchdog driver fixup for 6.8-rc1: - Add IRQ override quirks for some Infinity laptops and for TongFang GMxXGxx (David McFarland, Hans de Goede). - Clean up the ACPI NUMA code and fix it to ensure that fake_pxm is not the same as one of the real pxm values (Yuntao Wang). - Fix the fractional clock divider flags in the ACPI LPSS (Intel SoC) driver so as to prevent miscalculation of the values in the clock divider (Andy Shevchenko). - Adjust comments in the ACPI watchdog driver to prevent kernel-doc from complaining during documentation builds (Randy Dunlap). * acpi-resource: ACPI: resource: Add Infinity laptops to irq1_edge_low_force_override ACPI: resource: Add another DMI match for the TongFang GMxXGxx * acpi-numa: ACPI: NUMA: Fix the logic of getting the fake_pxm value ACPI: NUMA: Optimize the check for the availability of node values ACPI: NUMA: Remove unnecessary check in acpi_parse_gi_affinity() * acpi-soc: ACPI: LPSS: Fix the fractional clock divider flags * acpi-misc: ACPI: watchdog: fix kernel-doc warnings

ACPI: utils: Introduce helper for _DEP list lookup

2023-12-19T17:25:00+00:00

The ACPI LPSS driver and the Surface platform driver code use almost the same code pattern for checking if one ACPI device is present in the list returned by _DEP for another ACPI device. To reduce the resulting code duplication, introduce a helper for that called acpi_device_dep() and invoke it from both places. No intentional functional impact. Signed-off-by: Rafael J.

ACPI: utils: Return bool from acpi_evaluate_reference()

2023-12-15T09:46:04+00:00

There are only 4 users of acpi_evaluate_reference() and none of them actually cares about the reason why it fails. All of them are only interested in whether or not it is successful, so it can return a bool value indicating that. Modify acpi_evaluate_reference() as per the observation above and update its callers accordingly so as to get rid of useless code and local variables. The observable behavior of the kernel is not expected to change after this modification of the code. Signed-off-by: Rafael J. Wysocki

ACPI: LPSS: Fix the fractional clock divider flags

2023-12-12T19:40:37+00:00

The conversion to CLK_FRAC_DIVIDER_POWER_OF_TWO_PS uses wrong flags in the parameters and hence miscalculates the values in the clock divider. Fix this by applying the flag to the proper parameter.

ACPI: LPSS: use acpi_dev_uid_match() for matching _UID

2023-12-06T17:02:37+00:00

Now that we have _UID matching support for integer types, we can use acpi_dev_uid_match() for it. Signed-off-by: Raag Jadav Acked-by: Mika Westerberg Signed-off-by: Rafael J. Wysocki

Platform devices are now created by ACPI core on device enumeration on acpi_bus_scan() -> acpi_bus_attach() path after commit 48459340b92b ("ACPI / scan: use platform bus type by default for _HID enumeration"). No need to create them from LPSS unless we explicitly need to set acpi_lpss_pm_domain for them. Signed-off-by: Raag Jadav Reviewed-by: Mika Westerberg Signed-off-by: Rafael J. Wysocki
