2014-08-28mfd: twl4030-power: Fix PM idle pin configuration to not conflict with ↵Tony Lindgren2-11/+11
regulators Commit 43fef47f94a1 (mfd: twl4030-power: Add a configuration to turn off oscillator during off-idle) added support for configuring the PMIC to cut off resources during deeper idle states to save power. This however caused regression for n900 display power that needed the PMIC configuration to be disabled with commit d937678ab625 (ARM: dts: Revert enabling of twl configuration for n900). Turns out the root cause of the problem is that we must use TWL4030_RESCONFIG_UNDEF instead of DEV_GRP_NULL to avoid disabling regulators that may have been enabled before the init function for twl4030-power.c runs. With TWL4030_RESCONFIG_UNDEF we let the regulator framework control the regulators like it should. Here we need to only configure the sys_clken and sys_off_mode triggers for the regulators that cannot be done by the regulator framework as it's not running at that point. This allows us to enable the PMIC configuration for n900.

This defines the device tree bindings for the Toshiba TC3589x series of multi-purpose expanders. Only the stuff I can test is defined: GPIO and keypad. Others may implement more subdevices further down the road. This is to complement commit a435ae1d51e2f18414f2a87219fdbe068231e692 "mfd: Enable the tc3589x for Device Tree" which left off the definition of the device tree bindings.

2014-08-28drm/i915: Remove bogus __init annotation from DMI callbacksMathias Krause3-3/+3
The __init annotations for the DMI callback functions are wrong as this code can be called even after the module has been initialized, e.g. like this: # echo 1 > /sys/bus/pci/devices/0000:00:02.0/remove # modprobe i915 # echo 1 > /sys/bus/pci/rescan The first command will remove the PCI device from the kernel's device list so the second command won't see it right away. But as it registers a PCI driver it'll see it on the third command. If the system happens to match one of the DMI table entries we'll try to call a function in long released memory and generate an Oops, at best. Fix this by removing the bogus annotation. Modpost should have caught that one but it ignores section reference mismatches from the .rodata section. :/ Fixes: 25e341cfc33d ("drm/i915: quirk away broken OpRegion VBT") Fixes: 8ca4013d702d ("CHROMIUM: i915: Add DMI override to skip CRT...")

2014-08-28drm: fix division-by-zero on dumb_create()David Herrmann1-1/+2
Kinda unexpected, but DIV_ROUND_UP() can overflow if passed an argument bigger than UINT_MAX - DIVISOR. Fix this by testing for "!cpp" before using it in the following division. Note that DIV_ROUND_UP() is defined as: #define DIV_ROUND_UP(n,d) (((n) + (d) - 1) / (d)) ..this will obviously overflow if (n + d - 1) is bigger than UINT_MAX.

This patch simply adds a few pci_is_root_bus() tests to avoid passing a NULL pointer to PCI access functions, allowing the radeon driver to work in a QEMU 440FX machine with an assigned HD8570 on the emulated PCI root bus.

git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull trace buffer epoll hang fix from Steven Rostedt: "Josef Bacik found a bug in the ring_buffer_poll_wait() where the condition variable (waiters_pending) was set before being added to the poll queue via poll_wait(). This allowed for a small race window to happen where an event could come in, check the condition variable see it set to true, clear it, and then wake all the waiters. But because the waiter set the variable before adding itself to the queue, the waker could have cleared the variable after it was set and then miss waking it up as it wasn't added to the queue yet. Discussing this bug, we realized that a memory barrier needed to be added too, for the rare case that something polls for a single trace event to happen (and just one, no more to come in), and miss the wakeup due to memory ordering. Ideally, a memory barrier needs to be added on the writer side too, but as that will kill tracing performance and this is for a situation that tracing wasn't even designed for (who traces one instance of an event, use a printk instead!), this isn't worth adding the barrier. But we can in the future add the barrier for when the buffer goes from empty to the first event, as that would cover this case" * tag 'trace-fixes-v3.17-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace: trace: Fix epoll hang when we race with new entries

2014-08-26drm/msm: avoid flood of kernel logs on faultsRob Clark1-2/+2
87e956e9 changed the fault handler to return -ENOSYS, which causes the iommu driver to print out a huge splat. Which wouldn't be quite so bad if nothing ever faulted. But seems like some EXA composite operations generate quite a lot of (seemingly harmless) faults. That is probably a userspace problem, but the huge increase in verbosity from iommu fault dumps makes things kind of unusable. We probably should actually log *some* message (not conditional on drm.debug). But ratelimit it. Signed-off-by: Rob Clark <[email protected]>

2014-08-26drm/i915: Move intel_ddi_set_vc_payload_alloc(false) to haswell_crtc_disable()Ville Syrjälä1-4/+3
Somehow the intel_ddi_set_vc_payload_alloc(false) call has ended up in ironlake_crtc_disable() rather than haswell_crtc_disable(). Move it to the correct place. intel_ddi_disable_transcoder_func() already disables the vc payload allocation so this doesn't actually do anything more. The spec says we should wait for some kind of ack after frobbing the bit. We don't appear to do that currently, but if and when someone decides that we should do it, intel_ddi_set_vc_payload_alloc() would appear to be be the right place for it. So having the function call in haswell_crtc_disable() seems like the right thing for the future even if it does nothing currently.

2014-08-26drm/i915: fix plane/cursor handling when runtime suspendedPaulo Zanoni1-0/+24
If we're runtime suspended and try to use the plane interfaces, we will get a lot of WARNs saying we did the wrong thing. We need to get runtime PM references to pin the objects, and to change the fences. The pin functions are the ideal places for this, but intel_crtc_cursor_set_obj() doesn't call them, so we also have to add get/put calls inside it. There is no problem if we runtime suspend right after these functions are finished, because the registers written are forwarded to system memory. Note: for a complete fix of the cursor-dpms test case, we also need the patch named "drm/i915: Don't try to enable cursor from setplane when crtc is disabled". v2: - Narrow the put/get calls on intel_crtc_cursor_set_obj() (Daniel) v3: - Make get/put also surround the fence and unpin calls (Daniel and Ville). - Merge all the plane changes into a single patch since they're the same fix. - Add the comment requested by Daniel. v4: - Remove spurious whitespace (Ville). v5: - Remove intel_crtc_update_cursor() chunk since Ville did an equivalent fix in another patch (Ville). v6: - Remove unpin chunk: it will be on a separate patch (Ville, Chris, Daniel). v7: - Same thing, new color.

2014-08-26drm/i915: Ignore VBT backlight presence check on Acer C720 (4005U)Scot Doyle1-0/+3
commit c675949ec58ca50d5a3ae3c757892f1560f6e896 Author: Jani Nikula <[email protected]> Date: Wed Apr 9 11:31:37 2014 +0300 drm/i915: do not setup backlight if not available according to VBT prevents backlight setup on the Acer C720 (Core i3 4005U CPU), which has a misconfigured VBT. Apply quirk to ignore the VBT backlight presence check during backlight setup.

2014-08-25trace: Fix epoll hang when we race with new entriesJosef Bacik1-1/+15
Epoll on trace_pipe can sometimes hang in a weird case. If the ring buffer is empty when we set waiters_pending but an event shows up exactly at that moment we can miss being woken up by the ring buffers irq work. Since ring_buffer_empty() is inherently racey we will sometimes think that the buffer is not empty. So we don't get woken up and we don't think there are any events even though there were some ready when we added the watch, which makes us hang. This patch fixes this by making sure that we are actually on the wait list before we set waiters_pending, and add a memory barrier to make sure ring_buffer_empty() is going to be correct.
