2021-12-23platform/x86: system76_acpi: Guard System76 EC specific functionalityTim Crawford1-28/+30
Certain functionality or its implementation in System76 EC firmware may be different to the proprietary ODM EC firmware. Introduce a new bool, `has_open_ec`, to guard our specific logic. Detect the use of this by looking for a custom ACPI method name used in System76 firmware.

2021-11-02platform/x86: system76_acpi: Fix input device error handlingTim Crawford1-1/+0
Users on darp6 that do not have Open EC firmware have reported crashes on boot. Correct the error handling for the input device to fix it. Managed devices do not need to be explicitly unregistered or freed, as this is handled by devres. Drop the call to input_free_device.

2021-10-19platform/x86: system76_acpi: Add attribute group for kb_led_colorTim Crawford1-14/+10
Create the attribute groups for kb_led_color and set the `groups` field in kb_led. While touching it, also change its show method to use sysfs_emit() instead of sprintf().

2021-10-19platform/x86: system76_acpi: Add battery charging thresholdsTim Crawford1-0/+157
System76 laptops running open source EC firmware support configuring charging thresholds through ACPI methods. Expose this functionality through the standard sysfs entries charge_control_{start,end}_threshold.

2021-10-19platform/x86: system76_acpi: Replace Fn+F2 function for OLED modelsJeremy Soller1-0/+29
System76 laptops models with OLED displays do not support the default Fn+F2 behavior of turning the embedded display on and off. Some models instead introduce a new notify event that is used to lock the screen so the OS will put the display in a low power state.

2020-07-09platform/x86: system76-acpi: Fix brightness_set schedule while atomicNick Shipp1-6/+6
system76_set() was set as an LED ->brightness_set() callback, but it calls acpi_evaluate_object() which is not atomic-safe. Switch to the ->brightness_set_blocking() LED callback instead. Signed-off-by: Nick Shipp <git@segbrk.com> Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>
