-Subject: [PATCH] net: ethernet: enc28j60: add device tree support
-
-(Upstream commit 2dd355a007e44960ec049c75920ddb6778fec9ee)
-
-The following patch adds the required match table for device tree support
-(and while at, fix the indent). It's also possible to specify the
-MAC address in the DT blob.
-
-Also add the corresponding binding documentation file.

-+* Microchip ENC28J60
-+
-+This is a standalone 10 MBit ethernet controller with SPI interface.
-+
-+For each device connected to a SPI bus, define a child node within
-+the SPI master node.
-+
-+Required properties:
-+- compatible: Should be "microchip,enc28j60"
-+- reg: Specify the SPI chip select the ENC28J60 is wired to
-+- interrupt-parent: Specify the phandle of the source interrupt, see interrupt
-+ binding documentation for details. Usually this is the GPIO bank
-+ the interrupt line is wired to.
-+- interrupts: Specify the interrupt index within the interrupt controller (referred
-+ to above in interrupt-parent) and interrupt type. The ENC28J60 natively
-+ generates falling edge interrupts, however, additional board logic
-+ might invert the signal.
-+- pinctrl-names: List of assigned state names, see pinctrl binding documentation.
-+- pinctrl-0: List of phandles to configure the GPIO pin used as interrupt line,
-+ see also generic and your platform specific pinctrl binding
-+ documentation.
-+
-+Optional properties:
-+- spi-max-frequency: Maximum frequency of the SPI bus when accessing the ENC28J60.
-+ According to the ENC28J80 datasheet, the chip allows a maximum of 20 MHz, however,
-+ board designs may need to limit this value.
-+- local-mac-address: See ethernet.txt in the same directory.
-+
-+
-+Example (for NXP i.MX28 with pin control stuff for GPIO irq):
-+
-+ ssp2: ssp@80014000 {
-+ compatible = "fsl,imx28-spi";
-+ pinctrl-names = "default";
-+ pinctrl-0 = <&spi2_pins_b &spi2_sck_cfg>;
-+ status = "okay";
-+
-+ enc28j60: ethernet@0 {
-+ compatible = "microchip,enc28j60";
-+ pinctrl-names = "default";
-+ pinctrl-0 = <&enc28j60_pins>;
-+ reg = <0>;
-+ interrupt-parent = <&gpio3>;
-+ interrupts = <3 IRQ_TYPE_EDGE_FALLING>;
-+ spi-max-frequency = <12000000>;
-+ };
-+ };
-+
-+ pinctrl@80018000 {
-+ enc28j60_pins: enc28j60_pins@0 {
-+ reg = <0>;
-+ fsl,pinmux-ids = <
-+ MX28_PAD_AUART0_RTS__GPIO_3_3 /* Interrupt */
-+ >;
-+ fsl,drive-strength = <MXS_DRIVE_4mA>;
-+ fsl,voltage = <MXS_VOLTAGE_HIGH>;
-+ fsl,pull-up = <MXS_PULL_DISABLE>;
-+ };
-+ };
