Has anyone gotten the enc28j60 driver working in the drivers/net/ethernet/microchip directory?
I'm looking for any device tree structures that can help bring this up.
Everything I've found on the internet doesn't seem to work for Beaglebone.
I'm also aware of how woefully old enc28j60.c is and have updated it for
the device tree (adding 'compatible', etc.)
Here's my current DT for this device:
/* */
/dts-v1/;
/plugin/;
/ {
compatible = "ti,beaglebone", "ti,beaglebone-black";
/* identification */
part-number = "BB-ENC28J60-01";
version = "00A0";
/* state the resources this cape uses */
exclusive-use =
/* the pin header uses */
"P9.17", /* spi0_cs0 */
"P9.18", /* spi0_d1 */
"P9.21", /* spi0_d0 */
"P9.22", /* spi0_sclk */
/* the hardware ip uses */
"spi0";
fragment@0 {
target = <&am33xx_pinmux>;
__overlay__ {
/* default state has all gpios released and mode set to
uart1 */
bb_spi0_pins: pinmux_bb_spi0_pins {
pinctrl-single,pins = <
0x150 0x30 /* spi0_sclk.spi0_sclk,
INPUT_PULLUP | MODE0 */
0x154 0x30 /* spi0_d0.spi0_d0,
INPUT_PULLUP | MODE0 */
0x158 0x10 /* spi0_d1.spi0_d1,
OUTPUT_PULLUP | MODE0 */
0x15c 0x10 /* spi0_cs0.spi0_cs0,
OUTPUT_PULLUP | MODE0 */
>;
};
};
};
fragment@1 {
target = <&spi0>; /* spi0 is numbered correctly */
__overlay__ {
#address-cells = <1>;
#size-cells = <0>;
status = "okay";
pinctrl-names = "default";
pinctrl-0 = <&bb_spi0_pins>;
channel@0 {
#address-cells = <1>;
#size-cells = <0>;
compatible = "spidev";
reg = <0>;
spi-max-frequency =
<16000000>;
spi-cpha;
//reg = < 0x00002160 0x00000020 >;
interrupt-parent = < &cpu >;
interrupts = < 2 >;
clock-frequency = < 100000000 >;
baud-width = < 8 >; /* BAUD_WIDTH type NUMBER
*/
gpios = < &spi1_cs 0 0 >;
ethernet: enc28j60@0 {
compatible = "microchip,enc28j60";
spi-max-frequency = < 20000000 >;
reg = < 0 >;
interrupts = < 4 >;
interrupt_deassert_reg = < 0x00003000 >;
};
};
channel@1 {
#address-cells = <1>;
#size-cells = <0>;
compatible = "spidev";
reg = <1>;
spi-max-frequency = <16000000>;
};
};
};
