* gpio-button-hotplug: leave platform_device.dev.platform_data untouchedFurong Xu2017-08-211-2/+1
| | | | | | | | | | | | get platform_data from gpio_keys_button_dev.pdata, and fix a illegal pointer dereference like this: [ 51.143776] gpio-keys-polled gpio-keys-polled: missing poll_interval value [ 51.150852] gpio-keys-polled: probe of gpio-keys-polled failed with error -22 [ 828.159993] gpio-keys-polled gpio-keys-polled: no memory for button data [ 828.166821] gpio-keys-polled: probe of gpio-keys-polled failed with error -12 Signed-off-by: Furong Xu <xfr@outlook.com>

* kernel: gpio-button-hotplug: Add missing ONESHOT flag to threaded IRQ requestJohn Crispin2016-03-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Without the IRQF_ONESHOT flag in devm_request_threaded_irq() call I get following error: genirq: Threaded irq requested with handler=NULL and !ONESHOT for irq 56 gpio-keys gpio-keys: failed to request irq:56 for gpio:20 >From kernel/irq/manage.c: The interrupt was requested with handler = NULL, so we use the default primary handler for it. But it does not have the oneshot flag set. In combination with level interrupts this is deadly, because the default primary handler just wakes the thread, then the irq lines is reenabled, but the device still has the level irq asserted. Rinse and repeat.... While this works for edge type interrupts, we play it safe and reject unconditionally because we can't say for sure which type this interrupt really has. The type flags are unreliable as the underlying chip implementation can override them. Signed-off-by: Petr Štetiar <ynezz@true.cz> SVN-Revision: 48894
* kernel: gpio-button-hotplug: update to use threaded irq'sJohn Crispin2016-02-121-8/+5
| | | | | | | | | | | | Many gpio controllers 'cansleep' due to the fact that they are behind busses e.g. i2c etc. Using threaded irq's allows for 'sleep-able' gpio's to be used.

* gpio-button-hotplug: handle EPROBE_DEFER and other errorsHauke Mehrtens2015-07-261-5/+15
| | | | | | | | | | of_get_gpio_flags() could return an error like EPROBE_DEFER which was not handled before. This patch takes the code from gpio_keys_polled.c for error handling and also improves some other unrelated small parts. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> SVN-Revision: 46502

* gpio-button-hotplug: add wwan buttonHauke Mehrtens2014-01-141-0/+1
| | | | | | | | | | | The wimax key will be used as a generic wwan key starting with Linux 3.13. The brcm47xx target uses this key for the 3g buttons. Also remove the ifdef around KEY_WPS_BUTTON, this is in the kernel for a long time now. Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> SVN-Revision: 39290

* gpio-button-hotplug: use gpio_button_get_value() to initialize last_state.John Crispin2013-08-011-1/+1
| | | | | | | | | | | TL-WR720N-v3 has a slider switch composed of 2 GPIO buttons which can be used to swtich between 3 positions. At leat 1 button is in pressed state in any of those positions. Initialize 'last_state' as 0 (released) will cause the device to automatically enter failsafe mode on every bootup. Signed-off-by: Yousong Zhou <yszhou4tech@gmail.com> SVN-Revision: 37643
