## Bring up alternate hardware enablement

You can attach MAC/PHY components other than the hardware configuration provided by Qualcomm and bring them up.

Note

You must obtain the MAC/PHY driver and firmware from the respective vendor. Qualcomm is not responsible for these configuration changes.

To replace QPS615 with other PCIe based MAC/PHY, see [PCIe software
support for QPS615
switch](https://docs.qualcomm.com/bundle/publicresource/topics/80-70017-8/pcie.html#sub$pcie-software-support-feature-for-qps615).

### Retain QPS615 PCIe and replace QEP8121/AQR113C

To retain QPS615 PCIe and replace QEP8121/AQR113C with other PHY
components, do the following:

1. Based on the attached PHY recommendations, update all the parameters
in the `arch/arm64/boot/dts/qcom/qcs6490-addons-rb3gen2.dtsi` file.
2. Compile the software.

    A sample code for QEP PHY is as follows:

qep_vreg: qep_vreg {
              compatible = "regulator-fixed";
              regulator-name = "qep_vreg";
              gpio = <&pm7325_gpios 8 0>;
              regulator-min-microvolt = <1800000>;
              regulator-max-microvolt = <1800000>;
              enable-active-high;
              };

        qps615_eth1,qps615_eth1@pcie1_rp {
                 reg = <0x100 0x0 0x0 0x0 0x0>;
                 pinctrl-names = "default";
                 pinctrl-0 = <&napa_intn_wol_sig>;
                 qcom,phy-rst-gpio = <1>;
                 interrupts-extended = <&tlmm 101 IRQ_TYPE_EDGE_FALLING>;
                 interrupt-names = "wol_irq";
                 phy-supply = <&qep_vreg>;
                 qcom,phy-rst-delay-us = <20000>;
                 #address-cells = <1>;
                 #size-cells = <1>;
              };
        Copy to clipboard

    After flashing the modified software, the QPS615 driver scans the
physical devices connected to it and matches the device tree
information in the `qcs6490-addons-rb3gen2.dtsi` file.

Note

A PHY may fail to load due to mismatch between the
configuration in the `.dtsi` file and actual recommendations for the
PHY. In such cases, you must update the configuration in the `.dtsi`
file accordingly.

## AQR PHY enablement

Though AQR PHY for 10 GbE is optional, it is validated on reference RB3
Gen 2 development kit. You must flash the PHY firmware to the hardware
only once. However, when the AQR PHY is detected, the PHY driver is enabled by default.

Qualcomm verified the following AQR PHY firmware on RB3 Gen 2
Development Kit:

- Marvell firmware: `AQR-G4_v5.6.1-QR_Marvell_NoSwap_XFI_ID44874_VER1836.cld`
- Marvell proprietary flash burn tool is recommended for flashing Marvell AQR113 PHY.
- Contact Marvell Technology, Inc. to obtain the AQR PHY firmware.

### Detect the PHY

To detect the PHY, do the following:

1. Update the AQR PHY parameters in the
`arch/arm64/boot/dts/qcom/qcs6490-addons-rb3gen2.dtsi` file.
2. Compile the software.

    Sample code for AQR PHY:

aqr_vreg: aqr_vreg {
                 compatible = "regulator-fixed";
                 regulator-name = "aqr_vreg";
                 gpio = <&pm7250b_gpios 4 0>;
                 regulator-min-microvolt = <1800000>;
                 regulator-max-microvolt = <1800000>;
                 enable-active-high;
              };
        
        qps615_eth0,qps615_eth0@pcie1_rp {
                 reg = <0x0 0x0 0x0 0x0 0x0>;
                 pinctrl-names = "default";
                 pinctrl-0 = <&aqr_intn_wol_sig>;
                 qcom,phy-rst-gpio = <0>;
                 interrupts-extended = <&tlmm 141 IRQ_TYPE_EDGE_FALLING>;
                 interrupt-names = "wol_irq";
                 phy-supply = <&aqr_vreg>;
                 qcom,phy-rst-delay-us = <221000>;
                 #address-cells = <1>;
                 #size-cells = <1>;
              };
        Copy to clipboard
