Merge ACPI x86-specific changes, core updates, EC driver updates and APEI support updates for 4.19. These add a special platform driver for handling multiple I2C devices hooked up to the same device object in the ACPI tables, add some new quirks and remove one that is not needed any more. * acpi-x86: platform/x86: Add ACPI i2c-multi-instantiate pseudo driver ACPI / x86: utils: Remove status workaround from acpi_device_always_present() ACPI / x86: enable touchscreen on Dell Venue Pro 7139 * acpi-bus: ACPI: bus: Fix a pointer coding style issue Revert "ACPI / bus: Parse tables as term_list for Dell XPS 9570 and Precision M5530" * acpi-ec: ACPI / EC: Add another entry for Thinkpad X1 Carbon 6th ACPI / EC: Use ec_no_wakeup on ThinkPad X1 Yoga 3rd * acpi-apei: arm64 / ACPI: clean the additional checks before calling ghes_notify_sea()

In order to remove the additional check before calling the ghes_notify_sea(), make stub definition when !CONFIG_ACPI_APEI_SEA. After this cleanup, we can simply call the ghes_notify_sea() to let APEI driver handle the SEA notification.

2018-06-06ACPICA: IORT: Add PMCG node supprtRobin Murphy1-1/+9
PMCG nodes were added by IORT revision C, with the unfortunate oversight that it only defined a single base address, and thus was incapable of properly describing PMCG implementations with PMCG_CFGR.RELOC_CTRS = 1, where the counters are in a separate page from the control registers. Revision D corrects this by clarifying the existing field as the page 0 base address and adding a second field to describe the page 1 address when implemented.

2018-05-02ghes, EDAC: Fix ghes_edac registrationBorislav Petkov1-1/+1
Tony reported seeing "Internal error: Can't find EDAC structure" when injecting correctable errors due to the fact that ghes_edac would still load even if the whitelist won't hit. Drop the pr_err() in ghes_edac_report_mem_error() for now due to the hacky way how ghes_edac depends on ghes.c. While at it, make ghes_edac_register() return an error if it doesn't hit in the whitelist as it is the only sensible thing to do in that situation. Furthermore, move the call to it to happen last in ghes_probe() so that GHES initializing properly does not depend on ghes_edac init at all as latter is only reporting errors and not required for GHES's proper functioning.

Currently the ACPI scan has special handling for serial bus slaves, in that it makes it the responsibility of the slave device's parent to enumerate the device. To support other types of slave devices which require the same special handling but where the bus is not strictly a serial bus, such as devices on the HiSilicon LPC controller bus, rename acpi_is_serial_bus_slave() to acpi_device_enumeration_by_parent(), so that the name can fit the wider purpose. Also rename the associated device flag acpi_device_flags.serial_bus_slave to .enumeration_by_parent.

2018-03-21xen/acpi: upload _PSD info for non Dom0 CPUs tooJoao Martins1-0/+2
All uploaded PM data from non-dom0 CPUs takes the info from vCPU 0 and changing only the acpi_id. For processors which P-state coordination type is HW_ALL (0xFD) it is OK to upload bogus P-state dependency information (_PSD), because Xen will ignore any cpufreq domains created for past CPUs. Albeit for platforms which expose coordination types as SW_ANY or SW_ALL, this will have some unintended side effects. Effectively, it will look at the P-state domain existence and *if it already exists* it will skip the acpi-cpufreq initialization and thus inherit the policy from the first CPU in the cpufreq domain. This will finally lead to the original cpu not changing target freq to P0 other than the first in the domain. Which will make turbo boost not getting enabled (e.g. for 'performance' governor) for all cpus. This patch fixes that, by also evaluating _PSD when we enumerate all ACPI processors and thus always uploading the correct info to Xen. We export acpi_processor_get_psd() for that this purpose, but change signature to not assume an existent of acpi_processor given that ACPI isn't creating an acpi_processor for non-dom0 CPUs.

2018-03-18ACPICA: Remove calling of _STA from acpi_get_object_info()Hans de Goede1-2/+0
As the documentatuon above its declaration indicates, acpi_get_object_info() is intended for early probe usage and as such should not call any methods which may rely on op_regions, before this commit it was also calling _STA, which on some systems does rely on op_regions. Calling _STA before things are ready leads to errors such as these (under Linux, on some hardware): [ 0.123579] ACPI Error: No handler for Region [ECRM] (00000000ba9edc4c) [generic_serial_bus] (20170831/evregion-166) [ 0.123601] ACPI Error: Region generic_serial_bus (ID=9) has no handler (20170831/exfldio-299) [ 0.123618] ACPI Error: Method parse/execution failed \_SB.I2C1.BAT1._STA, AE_NOT_EXIST (20170831/psparse-550) End 2015 support for the _SUB method was removed for exactly the same reason. Removing current_status from struct acpi_device_info only has a limited impact. Within ACPICA it is only used by 2 debug messages, both of which are modified to no longer print it with this commit. Outside of ACPICA, there was one user in Linux, which has been patched to no longer use current_status in Torvald's current master. I've not checked if free_BSD or others are using the current_status field.

ACPICA commit a6c3c725c44dd44ad9d3f2b2a64351fdbe6e0014 For the kernel-resident ACPICA, optionally be silent about the NOT_FOUND case. Although this is potentially a serious problem, it can generate a lot of noise/errors on platforms whose firmware carries around a bunch of unused Package objects. To disable these errors, define ACPI_IGNORE_PACKAGE_RESOLUTION_ERRORS in the OS-specific header.

2018-02-22ACPICA: Integrate package handling with module-level codeSchmauss, Erik1-2/+6
ACPICA commit 8faf6fca445eb7219963d80543fb802302a7a8c7 This change completes the integration of the recent changes to package object handling with the module-level code support. For acpi_exec, the -ep flag is removed. This change allows table load to behave as if it were a method invocation. Before this, the definition block definition below would have loaded all named objects at the root scope. After loading, it would execute the if statements at the root scope. DefinitionBlock (...) { Name(OBJ1, 0) if (1) { Device (DEV1) { Name (_HID,0x0) } } Scope (DEV1) { Name (OBJ2) } } The above code would load OBJ1 to the namespace, defer the execution of the if statement and attempt to add OBJ2 within the scope of DEV1. Since DEV1 is not in scope, this would incur an AE_NOT_FOUND error. After this error is emitted, the if block is invoked and DEV1 and its _HID is added to the namespace. This commit changes the behavior to execute the if block in place rather than deferring it until all tables are loaded. The new behavior is as follows: insert OBJ1 in the namespace, invoke the if statement and add DEV1 and its _HID to the namespace, add OBJ2 to the scope of DEV1.

2018-02-22battery: Add the battery hooking APIOgnjen Galic1-0/+21
This is a patch that implements a generic hooking API for the generic ACPI battery driver. With this new generic API, drivers can expose platform specific behaviour via sysfs attributes in /sys/class/power_supply/BATn/ in a generic way. A perfect example of the need for this API are Lenovo ThinkPads. Lenovo ThinkPads have a ACPI extension that allows the setting of start and stop charge thresholds in the EC and battery firmware via ACPI. The thinkpad_acpi module can use this API to expose sysfs attributes that it controls inside the ACPI battery driver sysfs tree, under /sys/class/power_supply/BATN/. The file drivers/acpi/battery.h has been moved to include/acpi/battery.h and the includes inside ac.c, sbs.c, and battery.c have been adjusted to reflect that. When drivers hooks into the API, the API calls add_battery() for each battery in the system that passes it a acpi_battery struct. Then, the drivers can use device_create_file() to create new sysfs attributes with that struct and identify the batteries for per-battery attributes.
