ACPI: x86: s2idle: Fix a logic error parsing AMD constraints table

2023-09-13T07:47:59+00:00

[ Upstream commit 9cc8cd086f05d9a01026c65c98da88561e9c619e ] The constraints table should be resetting the `list` object after running through all of `info_obj` iterations. This adjusts whitespace as well as less code will now be included with each loop. This fixes a functional problem is fixed where a badly formed package in the inner loop may have incorrect data.

ACPI: x86: s2idle: Post-increment variables when getting constraints

2023-09-13T07:47:59+00:00

[ Upstream commit 3c6b1212d20bbbffcad5709ab0f2d5ed9b5859a8 ] When code uses a pre-increment it makes the reader question "why". In the constraint fetching code there is no reason for the variables to be pre-incremented so adjust to post-increment. No intended functional changes.

ACPI: thermal: Drop nocrt parameter

2023-09-02T07:14:37+00:00

commit 5f641174a12b8a876a4101201a21ef4675ecc014 upstream. The `nocrt` module parameter has no code associated with it and does nothing. As `crt=-1` has same functionality as what nocrt should be doing drop `nocrt` and associated documentation. This should fix a quirk for Gigabyte GA-7ZX that used `nocrt` and thus didn't function properly.

ACPI: resource: Fix IRQ override quirk for PCSpecialist Elimina Pro 16 M

2023-08-30T12:52:41+00:00

commit 453b014e2c294abf762d3bce12e91ce4b34055e6 upstream. It turns out that some PCSpecialist Elimina Pro 16 M models have "GM6BGEQ" as DMI product-name instead of "Elimina Pro 16 M", causing the existing DMI quirk to not work on these models. The DMI board-name is always "GM6BGEQ", so match on that instead.

ACPI: scan: Create platform device for CS35L56

2023-08-16T16:32:31+00:00

commit 1cd0302be5645420f73090aee26fa787287e1096 upstream. The ACPI device CSC3556 is a Cirrus Logic CS35L56 mono amplifier which is used in multiples, and can be connected either to I2C or SPI. There will be multiple instances under the same Device() node. Add it to ignore_serial_bus_ids and handle it in the serial-multi-instantiate driver. There can be a 5th I2cSerialBusV2, but this is an alias address and doesn't represent a real device. Ignore this by having a dummy 5th entry in the serial-multi-instantiate instance list with the name of a non-existent driver, on the same pattern as done for bsg2150.

ACPI: resource: Add IRQ override quirk for PCSpecialist Elimina Pro 16 M

2023-08-16T16:32:17+00:00

commit 56fec0051a69ace182ca3fba47be9c13038b4e3f upstream. The PCSpecialist Elimina Pro 16 M laptop model is a Zen laptop which needs to use the MADT IRQ settings override and which does not have an INT_SRC_OVR entry for IRQ 1 in its MADT. So this model needs a DMI quirk to enable the MADT IRQ settings override to fix its keyboard not working.

ACPI: resource: Honor MADT INT_SRC_OVR settings for IRQ1 on AMD Zen

2023-08-16T16:32:17+00:00

commit c6a1fd910d1bf8a0e3db7aebb229e3c81bc305c4 upstream. On AMD Zen acpi_dev_irq_override() by default prefers the DSDT IRQ 1 settings over the MADT settings. This causes the keyboard to malfunction on some laptop models (see Links), all models from the Links have an INT_SRC_OVR MADT entry for IRQ 1.

ACPI: resource: Always use MADT override IRQ settings for all legacy non i8042 IRQs

2023-08-16T16:32:17+00:00

commit 9728ac221160c5ea111879125a7694bb81364720 upstream. All the cases, were the DSDT IRQ settings should be used instead of the MADT override, are for IRQ 1 or 12, the PS/2 kbd resp. mouse IRQs. Simplify things by always honering the override for other legacy IRQs (for non DMI quirked cases). This allows removing the DMI quirks to honor the override for some non i8042 IRQs on some AMD ZEN based Lenovo models.

ACPI/IORT: Remove erroneous id_count check in iort_node_get_rmr_info()

2023-08-03T08:26:08+00:00

commit 003e6b56d780095a9adc23efc9cb4b4b4717169b upstream. According to the ARM IORT specifications DEN 0049 issue E, the "Number of IDs" field in the ID mapping format reports the number of IDs in the mapping range minus one. In iort_node_get_rmr_info(), we erroneously skip ID mappings whose "Number of IDs" equal to 0, resulting in valid mapping nodes with a single ID to map being skipped, which is wrong. Fix iort_node_get_rmr_info() by removing the bogus id_count check.
