Pull driver core patches from Greg KH: "Here's the big driver core pull request for 3.12-rc1. 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 to core files.

extcon: adc-jack: Use power efficient workqueue

2013-08-04T23:53:34Z

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. Signed-off-by: Mark Brown Acked-by: Viresh Kumar Signed-off-by: Chanwoo Choi Signed-off-by: Myungjoo Ham

extcon: arizona: Use power efficient workqueue

2013-08-04T23:53:34Z

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.

extcon: palmas: Option to disable ID/VBUS detection based on platform

2013-08-04T23:53:34Z

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. Signed-off-by: Laxman Dewangan Acked-by: Graeme Gregory Signed-off-by: Chanwoo Choi Signed-off-by: Myungjoo Ham

extcon: palams: add support for suspend/resume

2013-08-04T23:53:34Z

Add suspend/resume callbacks and support for wakeup from suspend on USB HOST or USB Device cable insertion or removal. Signed-off-by: Laxman Dewangan Acked-by: Graeme Gregory Signed-off-by: Chanwoo Choi Signed-off-by: Myungjoo Ham

extcon: palmas: enable ID_GND and ID_FLOAT detection always

2013-08-04T23:53:34Z

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.

extcon: palmas: remove assigning "edev.name" to palmas

2013-08-04T23:53:33Z

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.

extcon: Add an API to get extcon device from dt node

2013-08-04T23:52:45Z

Added an API of_extcon_get_extcon_dev() to be used by drivers to get extcon device in the case of dt boot (this can be used instead of extcon_get_extcon_dev()). Signed-off-by: Kishon Vijay Abraham I Signed-off-by: Chanwoo Choi Signed-off-by: Myungjoo Ham

extcon: convert extcon_class to use dev_groups

2013-07-25T23:34:39Z

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. Cc: MyungJoo Ham Acked-by: Chanwoo Choi Signed-off-by: Greg Kroah-Hartman
