2024-06-24cpufreq: simplify boolean parsing with kstrtobool in store functionPerry Yuan
Update the cpufreq store function to use kstrtobool for parsing boolean values. This simplifies the code and improves readability by using a standard kernel function for boolean string conversion.

2024-06-20cpufreq: amd-pstate: auto-load pstate driver by defaultPerry Yuan
If the `amd-pstate` driver is not loaded automatically by default, it is because the kernel command line parameter has not been added. To resolve this issue, it is necessary to call the `amd_pstate_set_driver()` function to enable the desired mode (passive/active/guided) before registering the driver instance. This ensures that the driver is loaded correctly without relying on the kernel command line parameter. When there is no parameter added to command line, Kernel config will provide the default mode to load. Meanwhile, user can add driver mode in command line which will override the kernel config default option.

The amd-pstate-epp driver has been implemented and resolves the performance drop issue seen in passive mode for shared memory type CPPC systems. Users who enable the active mode driver will not experience a performance drop compared to the passive mode driver.

2024-06-07HID: i2c-hid: elan: fix reset suspend current leakageJohan Hovold
The Elan eKTH5015M touch controller found on the Lenovo ThinkPad X13s shares the VCC33 supply with other peripherals that may remain powered during suspend (e.g. when enabled as wakeup sources). The reset line is also wired so that it can be left deasserted when the supply is off. This is important as it avoids holding the controller in reset for extended periods of time when it remains powered, which can lead to increased power consumption, and also avoids leaking current through the X13s reset circuitry during suspend (and after driver unbind). Use the new 'no-reset-on-power-off' devicetree property to determine when reset needs to be asserted on power down. Notably this also avoids wasting power on machine variants without a touchscreen for which the driver would otherwise exit probe with reset asserted.

2024-06-07dt-bindings: HID: i2c-hid: elan: add 'no-reset-on-power-off' propertyJohan Hovold
When the power supply is shared with other peripherals the reset line can be wired in such a way that it can remain deasserted regardless of whether the supply is on or not. This is important as it can be used to avoid holding the controller in reset for extended periods of time when it remains powered, something which can lead to increased power consumption. Leaving reset deasserted also avoids leaking current through the reset circuitry pull-up resistors. Add a new 'no-reset-on-power-off' devicetree property which can be used by the OS to determine when reset needs to be asserted on power down. Note that this property can also be used when the supply cannot be turned off by the OS at all.

2024-06-07dt-bindings: HID: i2c-hid: add dedicated Ilitek ILI2901 schemaJohan Hovold
The Ilitek ILI2901 touch screen controller was apparently incorrectly added to the Elan eKTH6915 schema simply because it also has a reset gpio and is currently managed by the Elan driver in Linux. The two controllers are not related even if an unfortunate wording in the commit message adding the Ilitek compatible made it sound like they were. Add a dedicated schema for the ILI2901 which does not specify the I2C address (which is likely 0x41 rather than 0x10 as for other Ilitek touch controllers) to avoid cluttering the Elan schema with unrelated devices and to make it easier to find the correct schema when adding further Ilitek controllers.
