The dv_timings_cap and enum_dv_timings subdev operations are implemented at the device level, but apply to pads. Create new variants of those operations at the pad level.

2014-11-18upstream: [media] v4l: Add source change eventArun Kumar K1-0/+8
This event indicates that the video device has encountered a source parameter change during runtime. This can typically be a resolution change detected by a video decoder OR a format change detected by an input connector. This needs to be nofified to the userspace and the application may be expected to reallocate buffers before proceeding. The application can subscribe to events on a specific pad or input port which it is interested in.

2014-11-18upstream: [media] v4l: Add timestamp source flags, mask and document themSakari Ailus1-0/+4
Some devices do not produce timestamps that correspond to the end of the frame. The user space should be informed on the matter. This patch achieves that by adding buffer flags (and a mask) for timestamp sources since more possible timestamping points are expected than just two. A three-bit mask is defined (V4L2_BUF_FLAG_TSTAMP_SRC_MASK) and two of the eight possible values is are defined V4L2_BUF_FLAG_TSTAMP_SRC_EOF for end of frame (value zero) V4L2_BUF_FLAG_TSTAMP_SRC_SOE for start of exposure (next value).

2014-11-18upstream: [media] v4l: add new tuner types for SDRAntti Palosaari1-0/+2
Define tuner types V4L2_TUNER_ADC and V4L2_TUNER_RF for SDR usage. ADC is used for setting sampling rate (sampling frequency) to SDR device. Another tuner type, named as V4L2_TUNER_RF, is possible RF tuner. Is is used to down-convert RF frequency to range ADC could sample. Having RF tuner is optional, whilst in practice it is almost always there. Also add checks to VIDIOC_G_FREQUENCY, VIDIOC_S_FREQUENCY and VIDIOC_ENUM_FREQ_BANDS only allow these two tuner types when device type is SDR (VFL_TYPE_SDR). For VIDIOC_G_FREQUENCY we do not check tuner type, instead override type with V4L2_TUNER_ADC in every case (requested by Hans in order to keep functionality in line with existing tuners and existing API does not specify it). Prohibit VIDIOC_S_HW_FREQ_SEEK explicitly when device type is SDR, as device cannot do hardware seek without a hardware demodulator.

That happens because struct v4l2_edid should be visible by both subdev and V4L2 APIs. So, it was moved to v4l2-common.h.

2014-11-18upstream: [media] v4l: add RF tuner channel bandwidth controlAntti Palosaari1-0/+2
Modern silicon RF tuners has one or more adjustable filters on signal path, in order to filter noise from desired radio channel. Add channel bandwidth control to tell the driver which is radio channel width we want receive. Filters could be then adjusted by the driver or hardware, using RF frequency and channel bandwidth as a base of filter calculations. On automatic mode (normal mode), bandwidth is calculated from sampling rate or tuning info got from userspace. That new control gives possibility to set manual mode and let user have more control for filters.

2014-11-18upstream: [media] v4l: add RF tuner gain controlsAntti Palosaari1-0/+11
Modern silicon RF tuners used nowadays has many controllable gain stages on signal path. Usually, but not always, there is at least 3 gain stages. Also on some cases there could be multiple gain stages within the ones specified here. However, I think that having these three controllable gain stages offers enough fine-tuning for real use cases. 1) LNA gain. That is first gain just after antenna input. 2) Mixer gain. It is located quite middle of the signal path, where RF signal is down-converted to IF/BB. 3) IF gain. That is last gain in order to adjust output signal level to optimal level for receiving party (usually demodulator ADC). Each gain stage could be set rather often both manual or automatic (AGC) mode. Due to that add separate controls for controlling operation mode. Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2014-11-18upstream: [media] v4l: ti-vpe: Add VPE mem to mem driverArchit Taneja1-0/+4
VPE is a block which consists of a single memory to memory path which can perform chrominance up/down sampling, de-interlacing, scaling, and color space conversion of raster or tiled YUV420 coplanar, YUV422 coplanar or YUV422 interleaved video formats. We create a mem2mem driver based primarily on the mem2mem-testdev example. The de-interlacer, scaler and color space converter are all bypassed for now to keep the driver simple. Chroma up/down sampler blocks are implemented, so conversion beteen different YUV formats is possible. Each mem2mem context allocates a buffer for VPE MMR values which it will use when it gets access to the VPE HW via the mem2mem queue, it also allocates a VPDMA descriptor list to which configuration and data descriptors are added. Based on the information received via v4l2 ioctls for the source and destination queues, the driver configures the values for the MMRs, and stores them in the buffer. There are also some VPDMA parameters like frame start and line mode which needs to be configured, these are configured by direct register writes via the VPDMA helper functions. The driver's device_run() mem2mem op will add each descriptor based on how the source and destination queues are set up for the given ctx, once the list is prepared, it's submitted to VPDMA, these descriptors when parsed by VPDMA will upload MMR registers, start DMA of video buffers on the various input and output clients/ports. When the list is parsed completely(and the DMAs on all the output ports done), an interrupt is generated which we use to notify that the source and destination buffers are done. The rest of the driver is quite similar to other mem2mem drivers, we use the multiplane v4l2 ioctls as the HW support coplanar formats.

2014-06-11USB: cdc-wdm: properly include types.hGreg Kroah-Hartman1-0/+2
commit 7ac3764fcafc06e72e1a79a9d998b9fdd900b2a6 upstream. The file include/uapi/linux/usb/cdc-wdm.h uses a __u16 so it needs to include types.h as well to make the build system happy.

commit 7d1896360f4d055d68565ef8ed56a677580f1a39 upstream. The include/uapi/linux/usb/cdc-wdm.h header defines cdc-wdm userspace APIs and should be exported by make headers_install.

2014-06-07drm/tegra: Remove gratuitous pad fieldThierry Reding1-1/+0
commit cbfbbabb89b37f6bad05f478d906a385149f288d upstream. The version of the drm_tegra_submit structure that was merged all the way back in 3.10 contains a pad field that was originally intended to properly pad the following __u64 field. Unfortunately it seems like a different field was dropped during review that caused this padding to become unnecessary, but the pad field wasn't removed at that time. One possible side-effect of this is that since the __u64 following the pad is now no longer properly aligned, the compiler may (or may not) introduce padding itself, which results in no predictable ABI. Rectify this by removing the pad field so that all fields are again naturally aligned. Technically this is breaking existing userspace ABI, but given that there aren't any (released) userspace drivers that make use of this yet, the fallout should be minimal.

2013-12-20ALSA: compress: Fix 64bit ABI incompatibilityTakashi Iwai1-3/+3
commit 6733cf572a9e20db2b7580a5dd39d5782d571eec upstream. snd_pcm_uframes_t is defined as unsigned long so it would take different sizes depending on 32 or 64bit architectures. As we don't want this ABI incompatibility, and there is no real 64bit user yet, let's make it the fixed size with __u32. Also bump the protocol version number to 0.1.2.

2013-11-20perf: Fix perf ring buffer memory orderingPeter Zijlstra1-5/+7
commit bf378d341e4873ed928dc3c636252e6895a21f50 upstream. The PPC64 people noticed a missing memory barrier and crufty old comments in the perf ring buffer code. So update all the comments and add the missing barrier. When the architecture implements local_t using atomic_long_t there will be double barriers issued; but short of introducing more conditional barrier primitives this is the best we can do.

2013-11-13drm: Pad drm_mode_get_connector to 64-bit boundaryChris Wilson1-0/+2
commit bc5bd37ce48c66e9192ad2e7231e9678880f6f8e upstream. Pavel Roskin reported that DRM_IOCTL_MODE_GETCONNECTOR was overwritting the 4 bytes beyond the end of its structure with a 32-bit userspace running on a 64-bit kernel. This is due to the padding gcc inserts as the drm_mode_get_connector struct includes a u64 and its size is not a natural multiple of u64s. 64-bit kernel: sizeof(drm_mode_get_connector)=80, alignof=8 sizeof(drm_mode_get_encoder)=20, alignof=4 sizeof(drm_mode_modeinfo)=68, alignof=4 32-bit userspace: sizeof(drm_mode_get_connector)=76, alignof=4 sizeof(drm_mode_get_encoder)=20, alignof=4 sizeof(drm_mode_modeinfo)=68, alignof=4 Fortuituously we can insert explicit padding to the tail of our structures without breaking ABI.
