Since 39b2bbe3 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Furthermore there is devm_gpiod_get_optional which is designed to get optional gpios. Simplify driver accordingly. Note this makes error checking more strict because only -ENOENT is ignored when searching for the GPIOs which is good.

由 Mika Westerberg 提交于
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.

If gpio controller requires waiting for read and write GPIO values, then we have to use the gpio cansleep api.

This patch moves the rfkill poll_work to the power efficient workqueue. This work does not have to be bound to the CPU that scheduled it, hence the selection of CPU that executes it would be left to the scheduler. Net result is that CPU idle times would be extended, resulting in power savings. This behaviour is enabled when CONFIG_WQ_POWER_EFFICIENT is selected. Cc: "John W.

Prevent unnecessary rfkill event generation when the state has not actually changed.

Convert delayed_work users doing cancel_delayed_work() followed by queue_delayed_work() to mod_delayed_work(). Most conversions are straight-forward. Ones worth mentioning are, * drivers/edac/edac_mc.c: edac_mc_workq_setup() converted to always use mod_delayed_work() and cancel loop in edac_mc_reset_delay_period() is dropped. * drivers/platform/x86/thinkpad_acpi.c: No need to remember whether watchdog is active or not. @fan_watchdog_active and related code dropped. * drivers/power/charger-manager.c: Seemingly a lot of delayed_work_pending() abuse going on here. [delayed_]work_pending() are unsynchronized and racy when used like this. I converted one instance in fullbatt_handler(). Please conver the rest so that it invokes workqueue APIs for the intended target state rather than trying to game work item pending state transitions. e.g. if timer should be modified - call mod_delayed_work(), canceled - call cancel_delayed_work[_sync](). * drivers/thermal/thermal_sys.c: thermal_zone_device_set_polling() simplified. Note that round_jiffies() calls in this function are meaningless. round_jiffies() work on absolute jiffies not delta delay used by delayed_work. v2: Tomi pointed out that __cancel_delayed_work() users can't be safely converted to mod_delayed_work(). They could be calling it from irq context and if that happens while delayed_work_timer_fn() is running, it could deadlock. __cancel_delayed_work() users are dropped.

__rfkill_switch_all() switches the state of devices of a given type; however, it does not switch devices of all type (RFKILL_TYPE_ALL). As a result, it ignores the keycode "KEY_RFKILL" from another module, i.e. eeepc-wmi.
