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 d8233468 ("platform/x86: intel-vbtn: Fix SW_TABLET_MODE always reporting 1 on the HP Pavilion 11 x360"). After commit 8169bd3e ("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.

Sending the switch state change twice within the same frame is invalid evdev protocol and only works if the client handles keys immediately as well. Processing events immediately is incorrect, it forces a fake order of events that does not exist on the device. Recent versions of libinput changed to only process the device state and SYN_REPORT time, so now the key event is lost.

This 2-in-1 model (Product name: Switch SA5-271) features a SW_TABLET_MODE that works as it would be expected, both when detaching the keyboard and when folding it behind the tablet body. It used to work until the introduction of the allow list at commit 8169bd3e ("platform/x86: intel-vbtn: Switch to an allow-list for SW_TABLET_MODE reporting"). Add this model to it, so that the Virtual Buttons device announces the EV_SW features again.

Remove PSU EEPROM configuration for systems class equipped with Mellanox chip Spectrum and ATOM CPU - system types MSN274x. Till now all the systems from this class used few types of power units, all equipped with EEPROM device with address space two bytes. Thus, all these devices have been handled by EEPROM driver "24c02". There is a new requirement is to support power unit replacement by "off the shelf" device, matching electrical required parameters. Such device can be equipped with different EEPROM type, which could be one byte address space addressing or even could be not equipped with EEPROM. In such case "24c02" will not work.

Add support to thinkpad_acpi for returning the status of the palm sensor. This patch builds on the work done previously for the input device implementation (which was not needed). Both lap and palm sensor are using sysfs and they are combined into the proxsensor block. Note: On some platforms, because of an issue in the HW implementation, the palm sensor presence may be incorrectly advertised as always enabled even if a palm sensor is not present. The palm sensor is intended for WWAN transmission power control and should be available and correct on all WWAN enabled systems. It is not recommended to use this interface for other use cases.

When user presses Fn-F5, the driver automatically changes throttle thermal policy (or fan boost mode, depending on laptop model). It would be convenient for userspace software to be able to poll on corresponding sysfs variable. For example, to show a notification about mode change.

Panasonic laptops (at least from CF-W4 onwards) have dedicated firmware registers for saving ac/dc and current brightness. They are a bit confusing so here's some explanations: AC_MIN_BRIGHT, AC_MAX_BRIGHT, DC_MIN_BRIGHT, DC_MAX_BRIGHT: Read-only. Values: 0x01 and 0x15 respectively. AC_CUR_BRIGHT, DC_CUR_BRIGHT: Read-Write. 0x00-0xFF. Store user-defined AC/DC brightness. However, they do not represent current brightness so they should be named AC_BRIGHT and DC_BRIGHT instead. CUR_BRIGHT (present since CF-W4): Read-Write. 0x00-0xFF. It sets the current brightness. It won't update itself if brightness is changed via other means, e.g. acpi_video0. Another CUR_BRIGHT (added since CF-W5): Read-Write. 0x01-0x15. Its value always synchronizes with current brightness. Not implemented in this version. Currently the backlight API interacts with AC_CUR_BRIGHT (probably because it's the only bl register available in earlier models?). This patch adds sysfs attributes for AC_CUR_BRIGHT, DC_CUR_BRIGHT and CUR_BRIGHT. It also fixes the error of https://lkml.org/lkml/2020/8/19/1264 . PS: I think the backlight API should interact with CUR_BRIGHT instead of AC_CUR_BRIGHT. But it involves complications like mapping between 0x01-0x15 or 0x00-0x14 (the backlight API) and 0x00-0xFF (CUR_BRIGHT). I'll leave the discussion for a later version. Signed-off-by:

According to the ACPI spec 9.1.1 _DSM (Device Specific Method), intel_hid_dsm_fn_mask, acquired from function index 0, is "a buffer containing one bit for each function index". When validitaing fn_index, it should be compared with corresponding bit. This buffer is usually longer than a byte. Depending on whether INTEL_HID_DSM_HEBC_V2_FN exist, it could be either "Buffer (0x02) { 0xFF, 0x01 }" or "Buffer (0x02) { 0xFF, 0x03 }". Probably it won't grow larger according to the description. On older platforms, available functions could be fewer or not supported at all, i.e., "Buffer (One) { 0x00 }".
