We set this up by activating EBI2, creating a chipselect entry as a subnode, and then putting the ethernet controller in a subnode of the chipselect. After the chipselect is configured, the SMSC device will be instantiated. Signed-off-by: Linus Walleij --- ChangeLog v3->v4: - Rebase on kernel v4.9-rc1 - Bindings and driver are merged so should be clear to apply. ChangeLog v2->v3: - Name chipselected device to ethernet-ebi2@2,0 - Update to the latest (v5) version of the bindings and what the EBI2 driver expects. - The SMSC911x bindings were ACKed by Arnd Bergmann and are merged to the netdev tree by David Miller. - The EBI2 bindings were ACKed by Rob Herring and a pull request for both bindings and driver is pending for ARM SoC. - This should be safe to merge for v4.9. ChangeLog v1->v2: - Use the new bindings with the first address cell indicating the chipselect - Use offset zero into the range in the EBI2 node (the range defines the base address of the chipselect) - Move all the XMEM setup to arrays in the EBI2 node --- arch/arm/boot/dts/qcom-apq8060-dragonboard.dts | 124 +++++++++++++++++++++++++ 1 file changed, 124 insertions(+) diff --git a/arch/arm/boot/dts/qcom-apq8060-dragonboard.dts b/arch/arm/boot/dts/qcom-apq8060-dragonboard.dts index 6c0038398ef2..7848e4c8bdb9 100644 --- a/arch/arm/boot/dts/qcom-apq8060-dragonboard.dts +++ b/arch/arm/boot/dts/qcom-apq8060-dragonboard.dts @@ -51,6 +51,29 @@ regulator-boot-on; }; + /* GPIO controlled ethernet power regulator */ + dragon_veth: xc622a331mrg { + compatible = "regulator-fixed"; + regulator-name = "XC6222A331MR-G"; + regulator-min-microvolt = <3300000>; + regulator-max-microvolt = <3300000>; + vin-supply = <&vph>; + gpio = <&pm8058_gpio 40 GPIO_ACTIVE_HIGH>; + enable-active-high; + pinctrl-names = "default"; + pinctrl-0 = <&dragon_veth_gpios>; + regulator-always-on; + }; + + /* VDDvario fixed regulator */ + dragon_vario: nds332p { + compatible = "regulator-fixed"; + regulator-name = "NDS332P"; + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <1800000>; + vin-supply = <&pm8058_s3>; + }; + /* This is a levelshifter for SDCC5 */ dragon_vio_txb: txb0104rgyr { compatible = "regulator-fixed"; @@ -167,6 +190,41 @@ bias-pull-up; }; }; + + dragon_ebi2_pins: ebi2 { + /* + * Pins used by EBI2 on the Dragonboard, actually only + * only CS2 is used by a real peripheral.
