2021-05-26platform/x86: dell-smbios-wmi: Fix oops on rmmod dell_smbiosHans de Goede1-1/+2
[ Upstream commit 3a53587423d25c87af4b4126a806a0575104b45e ] init_dell_smbios_wmi() only registers the dell_smbios_wmi_driver on systems where the Dell WMI interface is supported. While exit_dell_smbios_wmi() unregisters it unconditionally, this leads to the following oops: [ 175.722921] ------------[ cut here ]------------ [ 175.722925] Unexpected driver unregister!

2021-05-26platform/x86: intel_int0002_vgpio: Only call enable_irq_wake() when using s2idleHans de Goede2-25/+57
[ Upstream commit b68e182a3062e326b891f47152a3a1b84abccf0f ] Commit 871f1f2bcb01 ("platform/x86: intel_int0002_vgpio: Only implement irq_set_wake on Bay Trail") stopped passing irq_set_wake requests on to the parents IRQ because this was breaking suspend (causing immediate wakeups) on an Asus E202SA. This workaround for the Asus E202SA is causing wakeup by USB keyboard to not work on other devices with Airmont CPU cores such as the Medion Akoya E1239T. In hindsight the problem with the Asus E202SA has nothing to do with Silvermont vs Airmont CPU cores, so the differentiation between the 2 types of CPU cores introduced by the previous fix is wrong. The real issue at hand is s2idle vs S3 suspend where the suspend is mostly handled by firmware. The parent IRQ for the INT0002 device is shared with the ACPI SCI and the real problem is that the INT0002 code should not be messing with the wakeup settings of that IRQ when suspend/resume is being handled by the firmware. Note that on systems which support both s2idle and S3 suspend, which suspend method to use can be changed at runtime. This patch fixes both the Asus E202SA spurious wakeups issue as well as the wakeup by USB keyboard not working on the Medion Akoya E1239T issue. These are both fixed by replacing the old workaround with delaying the enable_irq_wake(parent_irq) call till system-suspend time and protecting it with a !pm_suspend_via_firmware() check so that we still do not call it on devices using firmware-based (S3) suspend such as the Asus E202SA. Note rather then adding #ifdef CONFIG_PM_SLEEP, this commit simply adds a "depends on PM_SLEEP" to the Kconfig since this drivers whole purpose is to deal with wakeup events, so using it without CONFIG_PM_SLEEP makes no sense.

2021-05-07platform/x86: thinkpad_acpi: Correct thermal sensor allocationMark Pearson1-9/+22
commit 6759e18e5cd8745a5dfc5726e4a3db5281ec1639 upstream. On recent Thinkpad platforms it was reported that temp sensor 11 was always incorrectly displaying 66C. It turns out the reason for this is that this location in EC RAM is not a temperature sensor but is the power supply ID (offset 0xC2). Based on feedback from the Lenovo firmware team the EC RAM version can be determined and for the current version (3) only the 0x78 to 0x7F range is used for temp sensors. I don't have any details for earlier versions so I have left the implementation unaltered there. Note - in this block only 0x78 and 0x79 are officially designated (CPU & GPU sensors). The use of the other locations in the block will vary from platform to platform; but the existing logic to detect a sensor presence holds.

2021-04-10platform/x86: thinkpad_acpi: Allow the FnLock LED to change stateEsteve Varela Colominas1-1/+7
[ Upstream commit 3d677f12ea3a2097a16ded570623567403dea959 ] On many recent ThinkPad laptops, there's a new LED next to the ESC key, that indicates the FnLock status. When the Fn+ESC combo is pressed, FnLock is toggled, which causes the Media Key functionality to change, making it so that the media keys either perform their media key function, or function as an F-key by default. The Fn key can be used the access the alternate function at any time. With the current linux kernel, the LED doens't change state if you press the Fn+ESC key combo. However, the media key functionality *does* change. This is annoying, since the LED will stay on if it was on during bootup, and it makes it hard to keep track what the current state of the FnLock is. This patch calls an ACPI function, that gets the current media key state, when the Fn+ESC key combo is pressed. Through testing it was discovered that this function causes the LED to update correctly to reflect the current state when this function is called. The relevant ACPI calls are the following: \_SB_.PCI0.LPC0.EC0_.HKEY.GMKS: Get media key state, returns 0x603 if the FnLock mode is enabled, and 0x602 if it's disabled. \_SB_.PCI0.LPC0.EC0_.HKEY.SMKS: Set media key state, sending a 1 will enable FnLock mode, and a 0 will disable it.

2021-03-30platform/x86: intel-vbtn: Stop reporting SW_DOCK eventsHans de Goede1-2/+10
commit 538d2dd0b9920334e6596977a664e9e7bac73703 upstream. Stop reporting SW_DOCK events because this breaks suspend-on-lid-close. SW_DOCK should only be reported for docking stations, but all the DSDTs in my DSDT collection which use the intel-vbtn code, always seem to use this for 2-in-1s / convertibles and set SW_DOCK=1 when in laptop-mode (in tandem with setting SW_TABLET_MODE=0). This causes userspace to think the laptop is docked to a port-replicator and to disable suspend-on-lid-close, which is undesirable. Map the dock events to KEY_IGNORE to avoid this broken SW_DOCK reporting. Note this may theoretically cause us to stop reporting SW_DOCK on some device where the 0xCA and 0xCB intel-vbtn events are actually used for reporting docking to a classic docking-station / port-replicator but I'm not aware of any such devices. Also the most important thing is that we only report SW_DOCK when it reliably reports being docked to a classic docking-station without any false positives, which clearly is not the case here. If there is a chance of reporting false positives then it is better to not report SW_DOCK at all.

2021-02-17platform/x86: hp-wmi: Disable tablet-mode reporting by defaultHans de Goede1-4/+10
[ Upstream commit 67fbe02a5cebc3c653610f12e3c0424e58450153 ] Recently userspace has started making more use of SW_TABLET_MODE (when an input-dev reports this). Specifically recent GNOME3 versions will: 1. When SW_TABLET_MODE is reported and is reporting 0: 1.1 Disable accelerometer-based screen auto-rotation 1.2 Disable automatically showing the on-screen keyboard when a text-input field is focussed 2. When SW_TABLET_MODE is reported and is reporting 1: 2.1 Ignore input-events from the builtin keyboard and touchpad (this is for 360° hinges style 2-in-1s where the keyboard and touchpads are accessible on the back of the tablet when folded into tablet-mode) This means that claiming to support SW_TABLET_MODE when it does not actually work / reports correct values has bad side-effects. The check in the hp-wmi code which is used to decide if the input-dev should claim SW_TABLET_MODE support, only checks if the HPWMI_HARDWARE_QUERY is supported. It does *not* check if the hardware actually is capable of reporting SW_TABLET_MODE. This leads to the hp-wmi input-dev claiming SW_TABLET_MODE support, while in reality it will always report 0 as SW_TABLET_MODE value. This has been seen on a "HP ENVY x360 Convertible 15-cp0xxx" and this likely is the case on a whole lot of other HP models. This problem causes both auto-rotation and on-screen keyboard support to not work on affected x360 models. There is no easy fix for this, but since userspace expects SW_TABLET_MODE reporting to be reliable when advertised it is better to not claim/report SW_TABLET_MODE support at all, then to claim to support it while it does not work. To avoid the mentioned problems, add a new enable_tablet_mode_sw module-parameter which defaults to false. Note I've made this an int using the standard -1=auto, 0=off, 1=on triplett, with the hope that in the future we can come up with a better way to detect SW_TABLET_MODE support. ATM the default auto option just does the same as off.

2021-02-07platform/x86: touchscreen_dmi: Add swap-x-y quirk for Goodix touchscreen on ↵Hans de Goede1-0/+18
Estar Beauty HD tablet [ Upstream commit 46c54cf2706122c37497896d56d67b0c0aca2ede ] The Estar Beauty HD (MID 7316R) tablet uses a Goodix touchscreen, with the X and Y coordinates swapped compared to the LCD panel. Add a touchscreen_dmi entry for this adding a "touchscreen-swapped-x-y" device-property to the i2c-client instantiated for this device before the driver binds. This is the first entry of a Goodix touchscreen to touchscreen_dmi.c, so far DMI quirks for Goodix touchscreen's have been added directly to drivers/input/touchscreen/goodix.c. Currently there are 3 DMI tables in goodix.c: 1. rotated_screen[] for devices where the touchscreen is rotated 180 degrees vs the LCD panel 2. inverted_x_screen[] for devices where the X axis is inverted 3. nine_bytes_report[] for devices which use a non standard touch report size Arguably only 3. really needs to be inside the driver and the other 2 cases are better handled through the generic touchscreen DMI quirk mechanism from touchscreen_dmi.c, which allows adding device-props to any i2c-client. Esp. now that goodix.c is using the generic touchscreen_properties code. Alternative to the approach from this patch we could add a 4th dmi_system_id table for devices with swapped-x-y axis to goodix.c, but that seems undesirable.

2021-01-27platform/x86: intel-vbtn: Drop HP Stream x360 Convertible PC 11 from allow-listHans de Goede1-6/+0
[ Upstream commit 070222731be52d741e55d8967b1764482b81e54c ] THe HP Stream x360 Convertible PC 11 DSDT has the following VGBS function: Method (VGBS, 0, Serialized) { If ((^^PCI0.LPCB.EC0.ROLS == Zero)) { VBDS = Zero } Else { VBDS = Zero } Return (VBDS) /* \_SB_.VGBI.VBDS */ } Which is obviously wrong, because it always returns 0 independent of the 2-in-1 being in laptop or tablet mode. This causes the intel-vbtn driver to initially report SW_TABLET_MODE = 1 to userspace, which is known to cause problems when the 2-in-1 is actually in laptop mode. During earlier testing this turned out to not be a problem because the 2-in-1 would do a Notify(..., 0xCC) or Notify(..., 0xCD) soon after the intel-vbtn driver loaded, correcting the SW_TABLET_MODE state. Further testing however has shown that this Notify() soon after the intel-vbtn driver loads, does not always happen. When the Notify does not happen, then intel-vbtn reports SW_TABLET_MODE = 1 resulting in a non-working touchpad. IOW the tablet-mode reporting is not reliable on this device, so it should be dropped from the allow-list, fixing the touchpad sometimes not working.

INT3515 ACPI nodes commit 9bba96275576da0cf78ede62aeb2fc975ed8a32d upstream. There are several reports about the tps6598x causing interrupt flood on boards with the INT3515 ACPI node, which then causes instability. There appears to be several problems with the interrupt. One problem is that the I2CSerialBus resources do not always map to the Interrupt resource with the same index, but that is not the only problem. We have not been able to come up with a solution for all the issues, and because of that disabling the device for now. The PD controller on these platforms is autonomous, and the purpose for the driver is primarily to supply status to the userspace, so this will not affect any functionality.

[ Upstream commit 74639cbf51d7c0304342544a83dfda354a6bd208 ] There isn't any need to overwrite the mode here in the driver with what has been detected by the firmware, such as DT or ACPI. In fact, if we use the SPI CS gpio descriptor feature we will overwrite the mode with SPI_MODE_0 where it already contains SPI_MODE_0 and more importantly SPI_CS_HIGH. Clearing the SPI_CS_HIGH bit causes the CS line to toggle when the device is probed when it shouldn't change, confusing the driver and making it fail to probe. Drop the assignment and let the spi core take care of it.

2020-12-30platform/x86: intel-vbtn: Fix SW_TABLET_MODE always reporting 1 on some HP ↵Hans de Goede1-4/+8
x360 models [ Upstream commit a4327979a19e8734ddefbd8bcbb73bd9905b69cd ] Some HP x360 models have an ACPI VGBS method which sets bit 4 instead of bit 6 when NOT in tablet mode at boot. Inspecting all the DSDTs in my DSDT collection shows only one other model, the Medion E1239T ever setting bit 4 and it always sets this together with bit 6. So lets treat bit 4 as a second bit which when set indicates the device not being in tablet-mode, as we already do for bit 6. While at it also prefix all VGBS constant defines with "VGBS_". Note this wrokaround was first added to the kernel as commit d823346876a9 ("platform/x86: intel-vbtn: Fix SW_TABLET_MODE always reporting 1 on the HP Pavilion 11 x360"). After commit 8169bd3e6e19 ("platform/x86: intel-vbtn: Switch to an allow-list for SW_TABLET_MODE reporting") got added to the kernel this was reverted, because with the new allow-list approach the workaround was no longer necessary for the model on which the issue was first reported. But it turns out that the workaround is still necessary because some affected models report a chassis-type of 31 which is on the allow-list.
