Add support to configure multiple pins in each register, existing implementation added by [1] does not support full fledge multiple pin configuration in single register, reports a pin clash when different modules configure different bits of same register. The issue reported and discussed here http://www.spinics.net/lists/arm-kernel/msg235213.html With pinctrl-single,bits-per-mux property specified, use function-mask property to find out number pins to configure. Allocate and register pin control functions based sub mask. Tested on da850/omap-l138 EVM. does not support variable submask for pins. does not support pinconf.

If a device have sleep and idle states in addition to the default state, look up these in the core and stash them in the pinctrl state container. Add accessor functions for pinctrl consumers to put the pins into "default", "sleep" and "idle" states passing nothing but the struct device * affected.

There exist controllers that don't support to set the pull to up or down separately but instead automatically set the pull direction based on embedded knowledge inside the controller, for example depending on the selected mux function of the pin. Therefore this patch adds another config option to use this default pull-state for a pin where it is not possible to know or decide if the pin will be pulled up or down.

The pinctrldev_list_mutex is sinked into the functions that actually traverse the list and lock it there. The code makes much more sense in this way. All the callers are in non-performance critical paths and the code is way more readable this way. Also refactor the function get_pinctrl_dev_from_devname() to follow the design pattern of get_pinctrl_dev_from_of_node() which is slightly simpler.

atlas6 is a SoC very similar with primaII, the register layput of pinctrl is same, but the pads, groups and functions of atlas6 have different layout with prima2, this patch 1. pull the definition of pads, groups and functions out of the pinctrl-sirf driver,and put them into soc-specific files 2. add pads, groups and functions tables for atlas6 3. let pads, groups and functions tables become the config data of the related dt compatible node, so the pinctrl-sirf can support all SiRF SoCs with the config data as private data. In this patch,we create a sirf dir, and let the old drivers/pinctrl/pinctrl-sirf.c = drivers/pinctrl/sirf/pinctrl-prima2.c + drivers/pinctrl/sirf/pinctrl-sirf.c drivers/pinctrl/sirf/pinctrl-atlas6.c is a newly created file for the pin layout of atlas6.

Merge tag 'trace-fixes-v3.10-rc3-v3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing fixes from Steven Rostedt: "This contains 4 fixes. The first two fix the case where full RCU debugging is enabled, enabling function tracing causes a live lock of the system. This is due to the added debug checks in rcu_dereference_raw() that is used by the function tracer. These checks are also traced by the function tracer as well as cause enough overhead to the function tracer to slow down the system enough that the time to finish an interrupt can take longer than when the next interrupt is triggered, causing a live lock from the timer interrupt. Talking this over with Paul McKenney, we came up with a fix that adds a new rcu_dereference_raw_notrace() that does not perform these added checks, and let the function tracer use that. The third commit fixes a failed compile when branch tracing is enabled, due to the conversion of the trace_test_buffer() selftest that the branch trace wasn't converted for. The forth patch fixes a bug caught by the RCU lockdep code where a rcu_read_lock() is performed when rcu is disabled (either going to or from idle, or user space). This happened on the irqsoff tracer as it calls task_uid(). The fix here was to use current_uid() when possible that doesn't use rcu locking. Which luckily, is always used when irqsoff calls this code." * tag 'trace-fixes-v3.10-rc3-v3' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: tracing: Use current_uid() for critical time tracing tracing: Fix bad parameter passed in branch selftest ftrace: Use the rcu _notrace variants for rcu_dereference_raw() and friends rcu: Add _notrace variation of rcu_dereference_raw() and hlist_for_each_entry_rcu()
