The TUSB7320 supports up to two downstream ports, and the TUSB7340 supports up to four. It includes a feature to configure the polarity of the PWRONx# signals, which are used to control other peripherals. In some systems, the default polarity needs to be inverted, which is supported by the hardware through software configuration. This patch series introduces TUSB73x0 PCIe device tree bindings and modifies the USB XHCI PCI driver to handle PWRONx# polarity via a device tree property. TUSB73x0 datasheet: https://www.ti.com/lit/ds/symlink/tusb7320.pdf v2: - Change the property type from bool to flag - Rename the property as ti,tusb7320-pwron-active-high v1: https://lore.kernel.org/all/20241004124521.53442-1-francesco@dolcini.it/ Parth Pancholi (2): dt-bindings: usb: add TUSB73x0 PCIe USB: xhci: add support for PWRON active high .../bindings/usb/ti,tusb73x0-pci.yaml | 60 +++++++++++++++++++ drivers/usb/host/xhci-pci.c | 3 + 2 files changed, 63 insertions(+) create mode 100644 Documentation/devicetree/bindings/usb/ti,tusb73x0-pci.yaml
