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) /* mcasp0_aclkx.spi1_sclk */
0x194 (PIN_INPUT | MUX_MODE3) /* mcasp0_fsx.spi1_d0 */
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: mcasp0_fsr.gpio3_19 */
0x1ac (PIN_OUTPUT_PULLDOWN | MUX_MODE7) /* SLP_TR: mcasp0_ahclkx.gpio3_21 */
0x044 (PIN_OUTPUT_PULLUP | MUX_MODE7) /* RESET: gpmc_a1.gpio1_17 */

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

On BBB, I'm using:

0x1a4 (PIN_INPUT | MUX_MODE7) /* IRQ:

0x1ac (PIN_OUTPUT_PULLDOWN | MUX_MODE7) /*

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?
