Symbol rate ratio were using a rough calculus, as the code was limited to 32 bits arithmetic. Change it to 64 bits, in order to better estimate the bandwidth low-pass filter on the demod. This should reduce the noise and improve reception. Reported-by:

Using 'i' for the guard interval temporary var is a bad idea, as 'i' is generally used by "anonymous" indexes. Let's rename modulation, fec and guard interval temp vars with a meaningful name, as that makes easier to understand the code and avoids cut-and-paste types of error. Signed-off-by:

We're using the anonymous 'i' to indicate the layer number on several places on the driver. That's not good, as some cut-and-paste type of change might be doing the wrong thing. So, call it as "layer" everywhere. Signed-off-by:

config looks like a hack that was added to tuner-core to allow some configuration of TDA8290 tuner (it's not used by any other driver). But with the new configuration options of tda8290 driver (no_i2c_gate and std_map), it's no longer sufficient. Change config to be void * instead, which allows passing tuner-dependent config struct to drivers. Also update saa7134 driver to reflect this change (no other driver uses this). Signed-off-by:

Hauppauge Nova-S-Plus DVB-S model 92001 does not lock on horizontal polarisation. According with the info provided at the BZ, model 92002 does. The difference is that, on model 92001, the tone select is done via isl6421, while, on other devices, this is done via cx24123 code. This patch adds a way to override the demod's set_tone at isl6421 driver. In order to avoid regressions, the override is enabled only for cx88 Nova S plus model 92001. For all other models and devices, the set_tone is provided by the demod driver. Patch originally proposed at bz@9476[1] by Michel Meyers and John Donoghue but applying the original patch would break support for all other devices based on isl6421.

rc_unregister_device already calls rc_free_device to free the passed device. But in one of ttusbir's probe fail paths, we call rc_unregister_device _and_ rc_free_device. This is wrong and results in a double free. Instead, set rc to NULL resulting in rc_free_device being a noop. Signed-off-by:

"enum dmx_ts_pes" and "typedef enum dmx_pes_type_t" are just the same enum declared twice, since Kernel (2.6.12). There's no reason to duplicate it there, and sparse complains about that: drivers/media/dvb-core/dmxdev.c:600:55: warning: mixing different enum types So, remove the internal define, keeping just the external one. Internally, use only "enum dmx_ts_pes", as it is too late to drop dmx_pes_type_t from the userspace API. Signed-off-by:

This patch fixes erroneous setup of the YUV order caused by not clearing FIMC_REG_MSCTRL_ORDER422_MASK bit field before setting proper FIMC_REG_MSCTRL_ORDER422 bits. This resulted in false colors for YUYV, YVYU, UYVY, VYUY color formats, depending in what sequence those were configured by user space. YUV order definitions are corrected so that following convention is used: | byte3 | byte2 | byte1 | byte0 -------+-------+-------+-------+------ YCBYCR | CR | Y | CB | Y YCRYCB | CB | Y | CR | Y CBYCRY | Y | CR | Y | CB CRYCBY | Y | CB | Y | CR Signed-off-by: -

The FIMC-LITE output DMA allows to configure different YUV order than the order at the camera input interface. Thus there is some limited colorspace conversion possible. This patch makes the color format variable be per FIMC-LITE input/output, rather than a global per device. This also fixes incorrect behavior where color format at the FIMC-LITE.N subdev's source pad is modified by VIDIOC_S_FMT ioctl on the related video node. YUV order definitions are corrected so that we use notation: | byte3 | byte2 | byte1 | byte0 -------+-------+-------+-------+------ YCBYCR | CR | Y | CB | Y YCRYCB | CB | Y | CR | Y CBYCRY | Y | CR | Y | CB CRYCBY | Y | CB | Y | CR Signed-off-by: -

This patch adds the ISP I2C bus controller driver files. Creating a standard I2C bus adapter, even if the driver doesn't actually communicate with the hardware and it is instead controlled by the ISP firmware running on the Cortex-A5, allows to use standard hardware description in the device tree. As the sensor would have actually had a standard V4L2 sub-device driver run on the host CPU. This approach allows to adapt the driver with a relatively small effort should the Imaging Subsystem architecture change so that the I2C bus is handled by the host's CPU OS, rather than the internal FIMC-IS ARM CPU firmware. The image sensor driver could be a standard I2C client driver, as in case of most existing image sensors. Signed-off-by:

This patch adds a set of core files of the Exynos4x12 FIMC-IS V4L2 driver. This includes main functionality like allocating memory, loading the firmware, FIMC-IS register interface and host CPU <-> IS command and error code definitions. The driver currently exposes a single subdev named FIMC-IS-ISP, which corresponds to the FIMC-IS ISP and DRC IP blocks. The FIMC-IS-ISP subdev currently supports only a subset of user controls. For other controls we need several extensions at the V4L2 API. The supported standard controls are: brightness, contrast, saturation, hue, sharpness, 3a_lock, exposure_time_absolute, white_balance_auto_preset, iso_sensitivity, iso_sensitivity_auto, exposure_metering_mode.

The 'camera' DT node needs to have sclk_cam0/1 and pxl_async0/1 clocks specified, while 'fimc' nodes should have only "fimc" and "sclk_fimc". "mux" and "parent" are leftovers from early versions of patches adding DT support, when the IP bus clock parent clock was being set by the driver. A better solution is needed to have e.g. clocks driver setting all required parent clocks, before clock consumers start using the clocks. Currently this binding doesn't describe parent clocks setup, it needs to be specified and handled somewhere else. Signed-off-by:

Currently the whole driver depends on MFD_SYSCON, which in turn depends on OF. To allow to use the driver on non-dt platforms (S5PV210) the SYSREG support is made conditional (it is needed only for dt enabled platforms) and MFD_SYSCON is selected if OF is enabled, instead of depending on OF.
