2013-07-29ARM: dts: omap5-uevm: document regulator signals used on the actual boardNishanth Menon
commit e00c27ef3b4c23e39d0a77b7c8e5be44c28001c7 (ARM: dts: OMAP5: Add Palmas MFD node and regulator nodes) introduced regulator entries for OMAP5uEVM. However, currently we use the Palmas regulator names which is used for different purposes on uEVM. Document the same based on 750-2628-XXX boards - which is meant to be supported by this dts.

2013-07-29tg3: Fix UDP fragments treated as RMCPNithin Sujir
The 5762 devices sometimes incorrectly treat udp fragments as RMCP packets and route to the APE. This patch sets the RX_MODE_IPV4_FRAG_FIX bit for these devices which enables the proper behaviour.

2013-07-29tg3: Enable support for timesync gpio outputNithin Sujir
The PTP_CAPABLE tg3 devices have a gpio output that is toggled when the free running counter matches a watchdog value. This patch adds support to set the watchdog and enable this feature. Since the output is controlled via bits in the EAV_REF_CLCK_CTL register, we have to read-modify-write it when we stop/resume.

2013-07-29tg3: Allow NVRAM programming when interface is downNithin Sujir
Previously, when the interface was brought down, the driver would set the power state to D3hot. In D3hot, we don't have access to the NVRAM. This patch removes the call to set the power state to PCI_D3hot in close. A following patch will implement the shutdown handler to properly set the D3hot state when the system is going down. Doing the above means that the TG3_PHYFLG_IS_LOW_POWER should not be checked to validate access to the NVRAM.

2013-07-29tg3: Remove incorrect switch to aux powerNithin Sujir
During probe, the driver is incorrectly switching the power to Vaux on the 5717 and later devices. At this point, we are in D0 state and drawing maximum power. We also definitely have Vmain available. It doesn't make sense to switch to Vaux since it has a lesser maximum power draw and we might go over the limit. On a new system, we observe that not all ports are recognized in some of the slots with this call in place.

Since the original merge of nouveau to upstream kernel, we were assuming that nv90 (and later) cards have 32 lines. Based on mmio traces of the binary driver, as well as PBUS error messages during read/write of the e070/e074 registers, we can conclude that nv92 has only 16 lines whereas nv94 (and later) cards have 32.

2013-07-29tracing: Change remove_event_file_dir() to clear "d_subdirs"->i_privateOleg Nesterov
Change remove_event_file_dir() to clear ->i_private for every file we are going to remove. We need to check file->dir != NULL because event_create_dir() can fail. debugfs_remove_recursive(NULL) is fine but the patch moves it under the same check anyway for readability. spin_lock(d_lock) and "d_inode != NULL" check are not needed afaics, but I do not understand this code enough. tracing_open_generic_file() and tracing_release_generic_file() can go away, ftrace_enable_fops and ftrace_event_filter_fops() use tracing_open_generic() but only to check tracing_disabled. This fixes all races with event_remove() or instance_delete(). f_op->read/write/whatever can never use the freed file/call, all event/* files were changed to check and use ->i_private under event_mutex. Note: this doesn't not fix other problems, event_remove() can destroy the active ftrace_event_call, we need more changes but those changes are completely orthogonal.

2013-07-30cpufreq: Fix cpufreq driver module refcount balance after suspend/resumeRafael J. Wysocki
Since cpufreq_cpu_put() called by __cpufreq_remove_dev() drops the driver module refcount, __cpufreq_remove_dev() causes that refcount to become negative for the cpufreq driver after a suspend/resume cycle. This is not the only bad thing that happens there, however, because kobject_put() should only be called for the policy kobject at this point if the CPU is not the last one for that policy. Namely, if the given CPU is the last one for that policy, the policy kobject's refcount should be 1 at this point, as set by cpufreq_add_dev_interface(), and only needs to be dropped once for the kobject to go away. This actually happens under the cpu == 1 check, so it need not be done before by cpufreq_cpu_put(). On the other hand, if the given CPU is not the last one for that policy, this means that cpufreq_add_policy_cpu() has been called at least once for that policy and cpufreq_cpu_get() has been called for it too. To balance that cpufreq_cpu_get(), we need to call cpufreq_cpu_put() in that case. Thus, to fix the described problem and keep the reference counters balanced in both cases, move the cpufreq_cpu_get() call in __cpufreq_remove_dev() to the code path executed only for CPUs that share the policy with other CPUs.
