| * net: rfkill: drop owner assignment from platform_driversWolfram Sang2014-10-201-1/+0

* | net: rfkill: gpio: Add default GPIO driver mappings for ACPIMika Westerberg2014-11-041-3/+15
|/ | | | | | | | | | | | | | | | | | | | | | | | | | The driver uses devm_gpiod_get_index(..., index) so that the index refers directly to the GpioIo resource under the ACPI device. The problem with this is that if the ordering changes we get wrong GPIOs. With ACPI 5.1 _DSD we can now use names instead to reference GPIOs analogous to Device Tree. However, we still have systems out there that do not provide _DSD at all. These systems must be supported as well. Luckily we now have acpi_dev_add_driver_gpios() that can be used to provide mappings for systems where _DSD is not provided and still take advantage of _DSD if it exists. This patch changes the driver to create default GPIO mappings if we are running on ACPI system. While there we can drop the indices completely and use devm_gpiod_get() with name instead.

| * rfkill-gpio: Use gpio cansleep versionLoic Poulain2014-05-071-11/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | If gpio controller requires waiting for read and write GPIO values, then we have to use the gpio cansleep api. Fix the rfkill_gpio_set_power which calls only the nonsleep version (causing kernel warning). There is no problem to use the cansleep version here because we are not in IRQ handler or similar context (cf rfkill_set_block).

This adds a new generic gpio rfkill driver to support rfkill switches which are controlled by gpios. The driver also supports passing in data about the clock for the radio, so that when rfkill is blocking, it can disable the clock. This driver assumes platform data is passed from the board files to configure it for specific devices.
