2014-04-23extcon: max14577: Choose muic_irqs according to device typeKrzysztof Kozlowski
This patch continues the preparation for adding support for max77836 device to existing max14577 driver. During probe choose muic_irqs according to device type. Currently there are only "max14577_muic_irqs" but later patch will add max77836 interrupts.

commit ca488 (extcon: of: Remove unnecessary function call by using the name of device_node) started using node name instead of device name to get the extcon device. This breaks dwc3-omap since it's not able to get the extcon device anymore. Fixed it by setting edev name of palmas to be the same as its node name.

2014-01-07extcon: gpio: Request gpio pin before modifying its stateGuenter Roeck
Commit 338de0ca (extcon: gpio: Use gpio driver/chip debounce if supported) introduced a call to gpio_set_debounce() before actually requesting the respective gpio pin from the gpio subsystem. The gpio subsystem expects that a gpio pin was requested before modifying its state. Not doing so results in a warning from gpiolib, and the gpio pin is auto-requested. This in turn causes the subsequent devm_gpio_request_one() to fail. So devm_gpio_request_one() must be called prior to calling gpio_set_debounce().

Lots of tiny changes here fixing up the way sysfs attributes are created, to try to make drivers simpler, and fix a whole class race conditions with creations of device attributes after the device was announced to userspace. All the various pieces are acked by the different subsystem maintainers" * tag 'driver-core-3.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (119 commits) firmware loader: fix pending_fw_head list corruption drivers/base/memory.c: introduce help macro to_memory_block dynamic debug: line queries failing due to uninitialized local variable sysfs: sysfs_create_groups returns a value. debugfs: provide debugfs_create_x64() when disabled rbd: convert bus code to use bus_groups firmware: dcdbas: use binary attribute groups sysfs: add sysfs_create/remove_groups for when SYSFS is not enabled driver core: add #include <linux/sysfs.h> to core files.

The debounce timeout is generally quite long and the work not performance critical so allow the scheduler to run the work anywhere rather than in the normal per-CPU workqueue.

None of the delayed work the driver schedules has particularly short delays and it is not performance sensitive so let the scheduler run it wherever is most efficient rather than in a per CPU workqueue by using the system power efficient workqueue.

Based on system design, platform needs to detect the VBUS or ID or both. Provide option to select this through platform data to disable part of cable detection through palmas-usb.

2013-08-05extcon: palmas: enable ID_GND and ID_FLOAT detection alwaysLaxman Dewangan
When integrating driver with Tegra platform, it is found that the ID pins get detected only once after booting system and further removal and re-insert does not detect the ID pin. Fixing this issue with enabling interrupt on ID_GND and ID_FLOAT always and clearing the status on LATCH register which actually occurred. Also if interrupt occurs with line status as zero then based on previous status, set the cable state. Add debug prints to display the cable state when any cable insertion/removal happen.

2013-08-05extcon: palmas: remove assigning "edev.name" to palmasKishon Vijay Abraham I
of_extcon_get_extcon_dev() uses dev_name for getting the reference to the extcon device. If the extcon driver assigns a different name other than dev_name, of_extcon_get_extcon_dev() wouldn't be able to find the reference to the extcon device. Since the client drivers of extcon-palmas would be using of_extcon_get_extcon_dev(), removed assigning edev.name in extcon-palmas.

The dev_attrs field of struct class is going away soon, dev_groups should be used instead. This converts the extcon_class code to use the correct field.

2013-07-03drivers: avoid format string in dev_set_nameKees Cook
Calling dev_set_name with a single paramter causes it to be handled as a format string. Many callers are passing potentially dynamic string content, so use "%s" in those cases to avoid any potential accidents, including wrappers like device_create*() and bdi_register().
