Signed-off-by: Andrew Bresticker Cc: Rob Herring Cc: Pawel Moll Cc: Mark Rutland Cc: Ian Campbell Cc: Kumar Gala Cc: Mathias Nyman Cc: Greg Kroah-Hartman --- Changes from v6: - Removed XUSB_DEV related clocks/resets. They will be consumed by a separate driver and binding. - Removed reg/interrupts properties. No changes from v5. Changes from v4: - Updated regulator names, as suggested by Thierry. No changes from v3. Changes from v2: - Added mbox-names property. Changes from v1: - Updated to use common mailbox bindings. - Added remaining XUSB-related clocks and resets. - Updated list of power supplies to be more accurate wrt to the hardware. --- .../bindings/usb/nvidia,tegra124-xhci.txt | 90 ++++++++++++++++++++++ 1 file changed, 90 insertions(+) create mode 100644 Documentation/devicetree/bindings/usb/nvidia,tegra124-xhci.txt diff --git a/Documentation/devicetree/bindings/usb/nvidia,tegra124-xhci.txt b/Documentation/devicetree/bindings/usb/nvidia,tegra124-xhci.txt new file mode 100644 index 0000000..5c980b0 --- /dev/null +++ b/Documentation/devicetree/bindings/usb/nvidia,tegra124-xhci.txt @@ -0,0 +1,90 @@ +NVIDIA Tegra xHCI controller +============================ + +The Tegra xHCI controller supports both USB2 and USB3 interfaces exposed +by the Tegra XUSB pad controller. + +Required properties: +-------------------- + - compatible: For Tegra124, must contain "nvidia,tegra124-xhci". + Otherwise, must contain '"nvidia,-xhci", "nvidia,tegra124-xhci"' + where is tegra132. + - clocks: Must contain an entry for each entry in clock-names. + See ../clock/clock-bindings.txt for details. + - clock-names: Must include the following entries: + - xusb_host + - xusb_host_src + - xusb_falcon_src + - xusb_ss + - xusb_ss_src + - xusb_ss_div2 + - xusb_hs_src + - xusb_fs_src + - pll_u_480m + - clk_m + - pll_e + - resets: Must contain an entry for each entry in reset-names. + See ../reset/reset.txt for details. + - reset-names: Must include the following entries: + - xusb_host + - xusb_ss + - xusb_src + Note that xusb_src is the shared reset for xusb_{ss,hs,fs,falcon,host}_src. + - mboxes: Must contain an entry for the XUSB mailbox channel. + See ../mailbox/mailbox.txt for details. + - mbox-names: Must include the following entries: + - xusb + - avddio-pex-supply: PCIe/USB3 analog logic power supply.
