💜 DESCRIPTION 💜

so the qcdwusb driver controls the interface logic for the Synopsys DesignWare USB 3.0 controller — the one that lives on various Qualcomm Snapdragon SoCs 🧚

the way that this driver is not the USB controller itself, bestie — it's the glue logic that makes the interface work 💅 it's giving backstage crew at the main character's concert, fr fr. the Synopsys DesignWare USB 3.0 controller is out there doing the visible slay, and qcdwusb is the one making sure the interface logic is handled so it all actually works ✨
