From 492d7a3038b154e1813a1ece913a5a27148fec19 Mon Sep 17 00:00:00 2001 From: Koen Kooi Date: Sat, 27 Sep 2014 09:55:44 +0200 Subject: [PATCH] logind: add support for TPS65217 Power Button This PMIC is found on TI AM335x based boards like the beaglebone and beaglebone black. root@beaglebone-white:~# udevadm info -a /dev/input/event0 Udevadm info starts with the device specified by the devpath and then walks up the chain of parent devices. It prints for every device found, all possible attributes in the udev rules key format. A rule to match, can be composed by the attributes of the device and the attributes from one single parent device. looking at device '/devices/ocp.3/44e0b000.i2c/i2c-0/0-0024/input/input0/event0': KERNEL=="event0" SUBSYSTEM=="input" DRIVER=="" looking at parent device '/devices/ocp.3/44e0b000.i2c/i2c-0/0-0024/input/input0': KERNELS=="input0" SUBSYSTEMS=="input" DRIVERS=="" ATTRS{name}=="tps65217_pwr_but" ATTRS{phys}=="" ATTRS{uniq}=="" ATTRS{properties}=="0" looking at parent device '/devices/ocp.3/44e0b000.i2c/i2c-0/0-0024': KERNELS=="0-0024" SUBSYSTEMS=="i2c" DRIVERS=="tps65217" ATTRS{name}=="tps65217" looking at parent device '/devices/ocp.3/44e0b000.i2c/i2c-0': KERNELS=="i2c-0" SUBSYSTEMS=="i2c" DRIVERS=="" ATTRS{name}=="OMAP I2C adapter" looking at parent device '/devices/ocp.3/44e0b000.i2c': KERNELS=="44e0b000.i2c" SUBSYSTEMS=="platform" DRIVERS=="omap_i2c" looking at parent device '/devices/ocp.3': KERNELS=="ocp.3" SUBSYSTEMS=="platform" DRIVERS=="" --- src/login/70-power-switch.rules | 1 + 1 file changed, 1 insertion(+) diff --git src/login/70-power-switch.rules src/login/70-power-switch.rules index a6997f7..695d246 100644 --- src/login/70-power-switch.rules +++ src/login/70-power-switch.rules @@ -10,5 +10,6 @@ ACTION=="remove", GOTO="power_switch_end" SUBSYSTEM=="input", KERNEL=="event*", SUBSYSTEMS=="acpi", TAG+="power-switch" SUBSYSTEM=="input", KERNEL=="event*", KERNELS=="thinkpad_acpi", TAG+="power-switch" SUBSYSTEM=="input", KERNEL=="event*", ATTRS{name}=="twl4030_pwrbutton", TAG+="power-switch" +SUBSYSTEM=="input", KERNEL=="event*", ATTRS{name}=="tps65217_pwr_but", TAG+="power-switch" LABEL="power_switch_end" -- 1.7.9.2
