 On above SoCs, a PDC controller is present in order to support scenarios where an interrupt line wired to a GPIO on the SoC should wake the device from sleep.
 
+PDC = Power Domain Controller

 Said PDC controller requires specific programming in order to be able to wake the device and fire an interrupt for the OS to handle and forward to a specific driver.
 
 On Windows, for these given SoCs, the driver responsible for implementing the GPIO controller, (Input/Output and Interrupts) is qcgpio.sys, providing an easy method in ACPI to set GPIOs and Declare Interrupts using GpioIo and GpioInt ACPI directives.

 The solution adopted in Windows by qualcomm consists of the following:
 
-- Qualcomm Assumes each tile of GPIOs on the SoC can have a very maximum of 64 GPIOs per tile
+- Qualcomm Assumes each tile of GPIOs on the SoC can have a very maximum of 64 GPIOs per tile. (Most likely derived from the MSFT GpioClx framework)
 - As such, for a device with 175 GPIOs supported, the tile count would for example be 3.
 - The GPIO driver on windows is responsible for deciding on its own what the value passed in ACPI exactly means.
 - It was therefore decided that for every value between 0 and 174, these would be normal GPIOs, and interrupts setup using those would not be wakeable
