Hi, With a patched 3.6rc7 on my beaglebone I can set the pinmux for pins using pinctrl and that seems to work. On the 3.2 vendor tree there was the omap_mux driver with an awesome debugfs interface: # cat /sys/kernel/debug/omap_mux/lcd_data0 name: lcd_data0.ehrpwm2A (0x44e108a0/0x8a0 = 0x0003), b NA, t NA mode: OMAP_PIN_OUTPUT | OMAP_MUX_MODE3 signals: lcd_data0 | gpmc_a0 | pr1_mii_mt0_clk | ehrpwm2A | NA | pr1_pru1_pru_r30_0 | pr1_pru1_pru_r31_0 | gpio2_6 Notice how it tells me that it's muxed the PWM in 2 ways: signal name (ehrpwm2A) and register content (0x0003). Compare to pinctrl: root@bone-mainline:/sys/kernel/debug/pinctrl/44e10800.pinmux# grep 8a0 * pinconf-pins:pin 40 (44e108a0): pingroups:pin 40 (44e108a0) pinmux-pins:pin 40 (44e108a0): 4a300000.pruss (GPIO UNCLAIMED) function pinmux_pruss_led_pins group pinmux_pruss_led_pins pins:pin 40 (44e108a0) pinctrl-single What is that pin muxed to? It is part of the 'pinmux_pruss_led_pins' in the DT, but debugfs remains mute on how pin 40 is muxed. regards, Koen-- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
