Qualcomm QUSB2 phy controller
|
|
=============================
|
|
|
|
QUSB2 controller supports LS/FS/HS usb connectivity on Qualcomm chipsets.
|
|
|
|
Required properties:
|
|
- compatible: compatible list, contains "qcom,msm8996-qusb2-phy".
|
|
- reg: offset and length of the PHY register set.
|
|
- #phy-cells: must be 0.
|
|
|
|
- clocks: a list of phandles and clock-specifier pairs,
|
|
one for each entry in clock-names.
|
|
- clock-names: must be "cfg_ahb" for phy config clock,
|
|
"ref" for 19.2 MHz ref clk,
|
|
"iface" for phy interface clock (Optional).
|
|
|
|
- vdda-pll-supply: Phandle to 1.8V regulator supply to PHY refclk pll block.
|
|
- vdda-phy-dpdm-supply: Phandle to 3.1V regulator supply to Dp/Dm port signals.
|
|
|
|
- resets: Phandle to reset to phy block.
|
|
|
|
Optional properties:
|
|
- nvmem-cells: Phandle to nvmem cell that contains 'HS Tx trim'
|
|
tuning parameter value for qusb2 phy.
|
|
|
|
- qcom,tcsr-syscon: Phandle to TCSR syscon register region.
|
|
|
|
Example:
|
|
hsusb_phy: phy@7411000 {
|
|
compatible = "qcom,msm8996-qusb2-phy";
|
|
reg = <0x7411000 0x180>;
|
|
#phy-cells = <0>;
|
|
|
|
clocks = <&gcc GCC_USB_PHY_CFG_AHB2PHY_CLK>,
|
|
<&gcc GCC_RX1_USB2_CLKREF_CLK>,
|
|
clock-names = "cfg_ahb", "ref";
|
|
|
|
vdda-pll-supply = <&pm8994_l12>;
|
|
vdda-phy-dpdm-supply = <&pm8994_l24>;
|
|
|
|
resets = <&gcc GCC_QUSB2PHY_PRIM_BCR>;
|
|
nvmem-cells = <&qusb2p_hstx_trim>;
|
|
};
