2020-07-09platform/x86: dell-wmi: add new keymap type 0x0012Y Paritcher
These are events with extended data. The extended data is currently ignored as userspace does not have a way to deal it. Ignore event with a type of 0x0012 and a code of 0xe035, as the keyboard controller takes care of Fn lock events by itself. This silences the following messages being logged when pressing the Fn-lock key on a Dell Inspiron 5593: dell_wmi: Unknown WMI event type 0x12 dell_wmi: Unknown key with type 0x0012 and code 0xe035 pressed This is consistent with the behavior for the Fn-lock key elsewhere in this file.

2020-07-09platform/x86: Add new intel_atomisp2_led driverHans de Goede
Many Bay Trail and Cherry Trail devices come with a camera attached to Intel's Image Signal Processor. Linux currently does not have a driver for these, so they do not work as a camera. Some of these camera's have a status LED which is controlled through a GPIO in some cases, e.g. on the Asus T100TA and Asus T200TA, there is a firmware issue where the LED gets turned on at boot. This commit adds a Linux LED driver for the camera LED on these devices. This driver will turn the LED off at boot and also allows controlling the LED (so the user can repurpose it) through the sysfs LED interface. Which GPIO is attached to the LED is usually not described in the ACPI tables, so this driver contains per-system info about the GPIO inside the driver. This means that this driver only works on systems the driver knows about. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

2020-06-29thermal: Rename set_mode() to change_mode()Andrzej Pietrasiewicz
set_mode() is only called when tzd's mode is about to change. Actual setting is performed in thermal_core, in thermal_zone_device_set_mode(). The meaning of set_mode() callback is actually to notify the driver about the mode being changed and giving the driver a chance to oppose such change.

2020-06-29thermal: Use mode helpers in driversAndrzej Pietrasiewicz
Use thermal_zone_device_{en|dis}able() and thermal_zone_device_is_enabled(). Consequently, all set_mode() implementations in drivers: - can stop modifying tzd's "mode" member, - shall stop taking tzd's lock, as it is taken in the helpers - shall stop calling thermal_zone_device_update() as it is called in the helpers - can assume they are called when the mode truly changes, so checks to verify that can be dropped Not providing set_mode() by a driver no longer prevents the core from being able to set tzd's mode, so the relevant check in mode_store() is removed. Other comments: - acpi/thermal.c: tz->thermal_zone->mode will be updated only after we return from set_mode(), so use function parameter in thermal_set_mode() instead, no need to call acpi_thermal_check() in set_mode() - thermal/imx_thermal.c: regmap writes and mode assignment are done in thermal_zone_device_{en|dis}able() and set_mode() callback - thermal/intel/intel_quark_dts_thermal.c: soc_dts_{en|dis}able() are a part of set_mode() callback, so they don't need to modify tzd->mode, and don't need to fall back to the opposite mode if unsuccessful, as the return value will be propagated to thermal_zone_device_{en|dis}able() and ultimately tzd's member will not be changed in thermal_zone_device_set_mode(). - thermal/of-thermal.c: no need to set zone->mode to DISABLED in of_parse_thermal_zones() as a tzd is kzalloc'ed so mode is DISABLED anyway Signed-off-by: Andrzej Pietrasiewicz <andrzej.p@collabora.com> [for acerhdf] Acked-by: Peter Kaestle <peter@piie.net> Reviewed-by: Amit Kucheria <amit.kucheria@linaro.org> Reviewed-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Link: https://lore.kernel.org/r/20200629122925.21729-8-andrzej.p@collabora.com

2020-06-14iio: core: pass parent device as parameter during allocationAlexandru Ardelean
The change passes the parent device to the iio_device_alloc() call. This also updates the devm_iio_device_alloc() call to consider the device object as the parent device by default. Having it passed like this, should ensure that any IIO device object already has a device object as parent, allowing for neater control, like passing the 'indio_dev' object for other stuff [like buffers/triggers/etc], and potentially creating iiom_xxx(indio_dev) functions. With this patch, only the 'drivers/platform/x86/toshiba_acpi.c' needs an update to pass the parent object as a parameter. In the next patch all devm_iio_device_alloc() calls will be handled.

2020-06-01platform/x86: asus_wmi: Reserve more space for struct bias_argsChris Chiu
On the ASUS laptop UX325JA/UX425JA, most of the media keys are not working due to the ASUS WMI driver fails to be loaded. The ACPI error as follows leads to the failure of asus_wmi_evaluate_method. ACPI BIOS Error (bug): AE_AML_BUFFER_LIMIT, Field [IIA3] at bit offset/length 96/32 exceeds size of target Buffer (96 bits) (20200326/dsopcode-203) No Local Variables are initialized for Method [WMNB] ACPI Error: Aborting method \_SB.ATKD.WMNB due to previous error (AE_AML_BUFFER_LIMIT) (20200326/psparse-531) The DSDT for the WMNB part shows that 5 DWORD required for local variables and the 3rd variable IIA3 hit the buffer limit. Method (WMNB, 3, Serialized) { .. CreateDWordField (Arg2, Zero, IIA0) CreateDWordField (Arg2, 0x04, IIA1) CreateDWordField (Arg2, 0x08, IIA2) CreateDWordField (Arg2, 0x0C, IIA3) CreateDWordField (Arg2, 0x10, IIA4) Local0 = (Arg1 & 0xFFFFFFFF) If ((Local0 == 0x54494E49)) .. } The limitation is determined by the input acpi_buffer size passed to the wmi_evaluate_method. Since the struct bios_args is the data structure used as input buffer by default for all ASUS WMI calls, the size needs to be expanded to fix the problem.

2020-06-01platform/x86: intel-vbtn: Only blacklist SW_TABLET_MODE on the 9 / "Laptop" ↵Hans de Goede
chasis-type The HP Stream x360 11-p000nd no longer report SW_TABLET_MODE state / events with recent kernels. This model reports a chassis-type of 10 / "Notebook" which is not on the recently introduced chassis-type whitelist Commit de9647efeaa9 ("platform/x86: intel-vbtn: Only activate tablet mode switch on 2-in-1's") added a chassis-type whitelist and only listed 31 / "Convertible" as being capable of generating valid SW_TABLET_MOD events. Commit 1fac39fd0316 ("platform/x86: intel-vbtn: Also handle tablet-mode switch on "Detachable" and "Portable" chassis-types") extended the whitelist with chassis-types 8 / "Portable" and 32 / "Detachable". And now we need to exten the whitelist again with 10 / "Notebook"... The issue original fixed by the whitelist is really a ACPI DSDT bug on the Dell XPS 9360 where it has a VGBS which reports it is in tablet mode even though it is not a 2-in-1 at all, but a regular laptop. So since this is a workaround for a DSDT issue on that specific model, instead of extending the whitelist over and over again, lets switch to a blacklist and only blacklist the chassis-type of the model for which the chassis-type check was added. Note this also fixes the current version of the code no longer checking if dmi_get_system_info(DMI_CHASSIS_TYPE) returns NULL.

2020-05-30pstore/ram: Introduce max_reason and convert dump_oopsKees Cook
Now that pstore_register() can correctly pass max_reason to the kmesg dump facility, introduce a new "max_reason" module parameter and "max-reason" Device Tree field. The "dump_oops" module parameter and "dump-oops" Device Tree field are now considered deprecated, but are now automatically converted to their corresponding max_reason values when present, though the new max_reason setting has precedence. For struct ramoops_platform_data, the "dump_oops" member is entirely replaced by a new "max_reason" member, with the only existing user updated in place. Additionally remove the "reason" filter logic from ramoops_pstore_write(), as that is not specifically needed anymore, though technically this is a change in behavior for any ramoops users also setting the printk.always_kmsg_dump boot param, which will cause ramoops to behave as if max_reason was set to KMSG_DUMP_MAX.
