The maximum number of bundles in the meter certificate was set to 8 which is much less than the maximum. Instead, since the bundles appear at the end of the file, set it based on the remaining file size from the bundle start position.

The Lenovo Yoga Tablet 2 Pro 1380F/L is a x86 ACPI tablet which ships with Android x86 as factory OS. Its DSDT contains a bunch of I2C devices which are not actually there, causing various resource conflicts. Enumeration of these is skipped through the acpi_quirk_skip_i2c_client_enumeration(). Add support for manually instantiating the I2C + other devices which are actually present on this tablet by adding the necessary device info to the x86-android-tablets module. Signed-off-by:

Not all subsystems support a device getting removed while there are still consumers of the device with a reference to the device. One example of this is the regulator subsystem. If a regulator gets unregistered while there are still drivers holding a reference a WARN() at drivers/regulator/core.c:5829 triggers, e.g.: WARNING: CPU: 1 PID: 1587 at drivers/regulator/core.c:5829 regulator_unregister Hardware name: Intel Corp. VALLEYVIEW C0 PLATFORM/BYT-T FFD8, BIOS BLADE_21.X64.0005.R00.1504101516 FFD8_X64_R_2015_04_10_1516 04/10/2015 RIP: 0010:regulator_unregister Call Trace: <TASK> regulator_unregister devres_release_group i2c_device_remove device_release_driver_internal bus_remove_device device_del device_unregister x86_android_tablet_remove On the Lenovo Yoga Tablet 2 series the bq24190 charger chip also provides a 5V boost converter output for powering USB devices connected to the micro USB port, the bq24190-charger driver exports this as a Vbus regulator. On the 830 (8") and 1050 ("10") models this regulator is controlled by a platform_device and x86_android_tablet_remove() removes platform_device-s before i2c_clients so the consumer gets removed first. But on the 1380 (13") model there is a lc824206xa micro-USB switch connected over I2C and the extcon driver for that controls the regulator. The bq24190 i2c-client *must* be registered first, because that creates the regulator with the lc824206xa listed as its consumer. If the regulator has not been registered yet the lc824206xa driver will end up getting a dummy regulator. Since in this case both the regulator provider and consumer are I2C devices, the only way to ensure that the consumer is unregistered first is to unregister the I2C devices in reverse order of in which they were created. For consistency and to avoid similar problems in the future change x86_android_tablet_remove() to unregister all device types in reverse order. Signed-off-by: -

AMD MP2 STB function provides a data buffer used to log debug information about the system execution during S2Idle suspend/resume. A data buffer known as the STB (Smart Trace Buffer) is a circular buffer which is a low-level log to assist in debugging by providing insights into any potential hangs or stalls that may occur during the S2Idle suspend/resume processes. The current PMC driver retrieves STB data from MP1, but there can be scenarios where MP1 might hang or become unresponsive, leading to the loss of critical data present in the STB buffer. This defeats the purpose of the STB buffer, which was originally meant to help identify system failures. This feature creates stb_read_previous_boot debugfs allows users to retrieve the STB log from MP2 specifically from the last occurrence of the S2Idle suspend/resume. A userspace daemon can access STB log of last S2Idle suspend/resume which can help to troubleshoot potential issues related to hangs or stalls during the S2Idle suspend/resume sequence. Reviewed-by:

Add support for an MCU powersave WMI call. This is intended to set the MCU in to a low-power mode when sleeping. This mode can cut sleep power use by around half. Reviewed-by:
-
Luke D. Jones authored
The previous work to allow the MCU to be resumed correctly after sleep and resume tried to take the shortest possible time. However as work continues in various other parts of the s2idle subsystems it has shown that it wasn't entirely reliable. If the MCU disable/enable call is done correctly the MCU fully removes its USB endpoints, and this shows as a full USB device reconnection on resume. When we tried to short this as much as possible sometimes the MCU doesn't get to complete what it needs to do before going to low-power and this affected the reconnection. Through trial it is found that the minimum time required is approx 1200ms to allow a proper disconnect and disable, and the same amount of time on resume is required to prevent a rapid disconnect/reconnect happening on seemingly random occasions. To be safe the time is now 1500ms for msleep. Reviewed-by:

Shift the call to dev_get_drvdata() up to top of the function block in all of the ppt_<name>() functions as part of a minor cleanup. Reviewed-by:

Luke D. Jones authored
Laptops with any of the ppt or nv tunables default to the minimum setting on boot so we can safely assume a stored value is correct. This patch adds storing of those values in the local struct, and enables reading of those values back. To prevent creating a series of byte holes in the struct the "<name>_available" bool is removed and `asus_sysfs_is_visible()` uses the `ASUS_WMI_DEVID_<name>` directly. Reviewed-by:

Since 2010, an LWN article covering WMI drivers exists: https://lwn.net/Articles/391230/ Since the introduction of the modern bus-based interface and other userspace tooling (bmfdec, lswmi, ...), this article is outdated and causes people to still submit new WMI drivers using the deprecated GUID-based interface.

devm_device_add_groups() is being removed from the kernel, so move the hsmp driver to use device_add_groups() instead. The logic is identical, when the device is removed the driver core will properly clean up and remove the groups, and the memory used by the attribute groups will be freed because it was created with dev_* calls, so this is functionally identical overall.
