The first version is available for example here [1]. This series tries to add support for two new ACPI 5.0 features that were either missing on incomplete in the current Linux kernel: * ACPI GPIO signaled events * ACPI GPIO operation regions The current ACPI GPIO support code already added preliminary support for GPIO signaled events but at the time we didn't have real hardware with real GPIO triggered events so it was never properly tested. Now there are devices like Asus T100TA transformer that uses these events so we were able to see that the ASL code is being executed when a GPIO interrupt is triggered. Changes to the previous version: * Moved module refcount manipulation to gpiod_request(). * Call achip acpi_gpio instead. * Fold patches [2,4/6] into one [2/5]. * Update changelog for [3/5] to state that no functional changes, it is rename only. * Explain ACPI operations regions a bit better in [5/5]. These patches apply on top of two patches from Alexandre Courbot [2] which introduce gpiochip_get_desc() function.
