Hi,
[deleted]

since somebody noticed me about several pinmux issues on this setup. I
will update them now with:

&am33xx_pinmux {
          spi1_pins: pinmux_spi1_pins {
                  pinctrl-single,pins = <
                          0x190 (PIN_INPUT_PULLDOWN | MUX_MODE3) /*

                          0x194 (PIN_INPUT | MUX_MODE3) /*

};

This is what [0] describes at page 11, I hope. Can somebody report if it
was successful to get openlabs with bb/bbw working?

(1.3.2 Pull-up and Pull-down Configuration)
On BBB, I'm using:

&am33xx_pinmux {
         spi1_pins: pinmux_spi1_pins {
                 pinctrl-single,pins = <
                         0x190 (PIN_INPUT_PULLDOWN | MUX_MODE3) /*

                         0x194 (PIN_INPUT | MUX_MODE3) /*

                         0x198 (PIN_OUTPUT_PULLDOWN | MUX_MODE3) /*
mcasp0_axr0.spi1_d1 */
                         0x19c (PIN_OUTPUT_PULLUP | MUX_MODE3) /*
mcasp0_ahclkr.spi1_cs0 */
                         0x1a4 (PIN_INPUT | MUX_MODE7)  /* IRQ:

                         0x1ac (PIN_OUTPUT_PULLDOWN | MUX_MODE7) /*

                         0x044 (PIN_OUTPUT_PULLUP | MUX_MODE7) /*

                 >;
         };
};


&spi1 {
         status = "okay";
         pinctrl-names = "default";
         pinctrl-0 = <&spi1_pins>;
         at86rf231@0 {
                 compatible = "atmel,at86rf231";
                 spi-max-frequency = <7500000>;
                 reg = <0>;
                 interrupts = <19 4>;
                 interrupt-parent = <&gpio3>;
                 reset-gpio = <&gpio1 17>;
Here you are missing the initial state of the reset gpio pin status.

It has to be something like this:
	
		reset-gpio = <&gpio1 17 1>;

                 sleep-gpio = <&gpio3 31>;
Same here also...

		sleep-gpio = <&gpio3 31 1>;

                 xtal-trim = /bits/ 8 <0xF>;
         };
};


At probe time, I get

Using e.g. "gpio1_17" doesn't compile, nor do other guesses.  What
syntax is expected for reset-gpio and sleep-gpio?

My kernel id bluetooth-next pulled Monday,

Linux beaglebone 4.0.0-rc7-244798-gf86c0e3 #1 SMP Wed Apr 15 10:34:12
EDT 2015 armv7l GNU/Linux


With those changes the "arguments longer than property" message does go away. I now get this probe error:
