They are dominated by the removal of the .owner field in platform drivers. They touch a lot of files, but they are "simple" changes, just removing a line in a structure. Other than that, a few minor driver core and debugfs changes. There are some ath9k patches coming in through this tree that have been acked by the wireless maintainers as they relied on the debugfs changes.

* | rtc: snvs: fix build with CONFIG_PM_SLEEP disabledGuenter Roeck2014-12-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 7654e9d4fd8f ("drivers/rtc/rtc-snvs: fix suspend/resume") replaces SIMPLE_DEV_PM_OPS with direct declaration of snvs_rtc_pm_ops, but does so outside #ifdef CONFIG_PM_SLEEP. This causes the driver build to fail if CONFIG_PM_SLEEP is not configured.

* | drivers/rtc/rtc-snvs: fix suspend/resumeSanchayan Maity2014-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The alarm interrupt handler also reads registers which are part of SNVS and need clocks enabled. However, the resume function is called after IRQ's have been enabled, hence this leads to a abort: Unhandled fault: external abort on non-linefetch (0x1008) at 0x908c604c Internal error: : 1008 [#1] ARM Modules linked in: CPU: 0 PID: 421 Comm: sh Not tainted 3.18.0-rc5-00135-g0689c67-dirty #1592 task: 8e03e800 ti: 8cad8000 task.ti: 8cad8000 PC is at snvs_rtc_irq_handler+0x14/0x74 LR is at handle_irq_event_percpu+0x3c/0x144 Fix this by using the .{suspend/resume}_noirq callbacks instead of .{suspend/resume} .

* | drivers/rtc/rtc-snvs: add clock supportSanchayan Maity2014-12-10
|/ | | | | | | | | | | | | | | | | | Add clock enable and disable support for the SNVS peripheral, which is required for using the RTC within the SNVS block. The clock is not strictly enforced, as this would break the i.MX devices. The clocking for the i.MX devices seems to be enabled elsewhere and enabling RTC SNVS for Vybrid results in a crash. This patch adds the clock support but also makes it optional so Vybrid platform can use the clock if defined while making sure not to break i.MX.

* Drivers: rtc: remove __dev* attributes.Greg Kroah-Hartman2013-01-03
| | | | | | | | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.
