2015-05-21Input: smtpe-ts - wait 50mS until polling for pen-upMarek Vasut1-1/+1
Wait a little bit longer, 50mS instead of 20mS, until the driver starts polling for pen-up. The problematic behavior before this patch is applied is as follows. The behavior was observed on the STMPE610QTR controller. Upon a physical pen-down event, the touchscreen reports one set of x-y-p coordinates and a pen-down event. After that, the pen-up polling is triggered and since the controller is not ready yet, the polling mistakenly detects a pen-up event while the physical state is still such that the pen is down on the touch surface. The pen-up handling flushes the controller FIFO, so after that, all the samples in the controller are discarded. The controller becomes ready shortly after this bogus pen-up handling and does generate again a pen-down interrupt. This time, the controller contains x-y-p samples which all read as zero. Since pressure value is zero, this set of samples is effectively ignored by userland. In the end, the driver just bounces between pen-down and bogus pen-up handling, generating no useful results. Fix this by giving the controller a bit more time before polling it for pen-up.

Try to detect the event signature of a VMmouse input device and back off for such devices.

Commit 47d68979cc968535cb87f3e5f2e6a3533ea48fbd restored this variable after the call for later re-use. Unfortunetly the restore was done after the referenced variable "bio" was advanced.

2015-05-20ib/cm: Change reject message type when destroying cm_idTed Kim1-1/+1
Problem reported by: Ted Kim <ted.h.kim@oracle.com>: We have a case where a Linux system and a non-Linux system are trying to interoperate. The Linux host is the active side and starts the connection establishment, but later decides to not go through with the connection setup and does rdma_destroy_id(). The rdma_destroy_id() eventually works its way down to cm_destroy_id() in core/cm.c, where a REJ is sent. The non-Linux system has some trouble recognizing the REJ because of: A. CM states which can't receive the REJ B. Some issues about REJ formatting (missing comm ID) ISSUE A: That part of the spec says, a Consumer Reject REJ can be sent for a connection abort, but it goes further and says: can send a REJ message with a "Consumer Reject" Reason code if they are in a CM state (i.e. REP Rcvd, MRA(REP) Sent, REQ Rcvd, MRA Sent) that allows a REJ to be sent (lines 35-38). Of the states listed there in that sentence, it would seem to limit the active side to using the Consumer Reject (for the abort case) in just the REP-Rcvd and MRA-REP-Sent states. That is basically only after the active side sees a REP (or alternatively goes down the state transitions to timeout in which case a Timeout REJ is sent). As a fix, in cm-destroy-id() move the IB-CM-MRA-REQ-RCVD case to the same as REQ-SENT. Essentially, make a REJ sent after getting an MRA on active side a timeout rather than Consumer- Reject, which is arguably more correct with the CM state diagrams previous to getting a REP.

2015-05-20net: phy: Make sure phy_start() always re-enables the phy interruptsTim Beale1-13/+16
This is an alternative way of fixing: commit db9683fb412d ("net: phy: Make sure PHY_RESUMING state change is always processed") When the PHY state transitions from PHY_HALTED to PHY_RESUMING, there are two things we need to do: 1). Re-enable interrupts (and power up the physical link, if powered down) 2). Update the PHY state and net-device based on the link status. There's no strict reason why #1 has to be done from within the main phy_state_machine() function. There is a risk that other changes to the PHY (e.g. setting speed/duplex, which calls phy_start_aneg()) could cause a subsequent state transition before phy_state_machine() has processed the PHY_RESUMING state change. This would leave the PHY with interrupts disabled and/or still in the BMCR_PDOWN/low-power mode. Moving enabling the interrupts and phy_resume() into phy_start() will guarantee this work always gets done. As the PHY is already in the HALTED state and interrupts are disabled, it shouldn't conflict with any work being done in phy_state_machine(). The downside of this change is that if the PHY_RESUMING state is ever entered from anywhere else, it'll also have to repeat this work.

2015-05-19xen/events: don't bind non-percpu VIRQs with percpu chipDavid Vrabel2-5/+9
A non-percpu VIRQ (e.g., VIRQ_CONSOLE) may be freed on a different VCPU than it is bound to. This can result in a race between handle_percpu_irq() and removing the action in __free_irq() because handle_percpu_irq() does not take desc->lock. The interrupt handler sees a NULL action and oopses. Only use the percpu chip/handler for per-CPU VIRQs (like VIRQ_TIMER). # cat /proc/interrupts | grep virq 40: 87246 0 xen-percpu-virq timer0 44: 0 0 xen-percpu-virq debug0 47: 0 20995 xen-percpu-virq timer1 51: 0 0 xen-percpu-virq debug1 69: 0 0 xen-dyn-virq xen-pcpu 74: 0 0 xen-dyn-virq mce 75: 29 0 xen-dyn-virq hvc_console Signed-off-by: David Vrabel <david.vrabel@citrix.com> Cc: <stable@vger.kernel.org>

2015-05-19pwm: img: Impose upper and lower timebase steps valueNaidu Tellapati1-12/+64
The PWM hardware on Pistachio platform has a maximum timebase steps value to 255. To fix it, let's introduce a compatible-specific data structure to contain the SoC-specific details and use it to specify a maximum timebase. Also, let's limit the minimum timebase to 16 steps, to allow a sane range of duty cycle steps.

2015-05-19drm/exynos: mixer: don't dump registers under spinlockTobias Jakobi1-4/+4
mixer_regs_dump() was called in mixer_run(), which was called under the register spinlock in mixer_graph_buffer() and vp_video_buffer(). This would trigger a sysmmu pagefault with drm.debug=0xff because of the large delay caused by the register dumping. To keep consistency also move register dumping out of mixer_stop(), which is the counterpart to mixer_run().

2015-05-19drm/exynos: mixer: cleanup pixelformat handlingTobias Jakobi1-10/+23
Move the defines for the pixelformats that the mixer supports out of mixer_graph_buffer() to the top of the source. Then select the mixer pixelformat (pf) in mixer_graph_buffer() based on the plane's pf (and not bpp). Also add handling of RGB565 and XRGB1555 to the switch statement and exit early if the plane has an unsupported pf. Partially based on 'drm/exynos: enable/disable blend based on pixel format' by Gustavo Padovan <gustavo.padovan@collabora.co.uk>. v2: Use the shorter MXR_FORMAT as prefix. v3: Re-add ARGB8888 because of compatibility reasons (suggested by Joonyoung Shim).

The video processor (VP) supports four formats: NV12, NV21 and its tiled variants. All these formats are bi-planar, so the buffer count in vp_video_buffer() is always 2.
