2013-04-08[media] tuner-core: Change config from unsigned int to void *Ondrej Zary
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).

2013-04-08[media] cx88: kernel bz#9476: Fix tone setting for Nova-S+ model 92001Mauro Carvalho Chehab
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.

2013-04-04[media] exynos4-is: Correct input DMA YUV order configurationSylwester Nawrocki
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: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-04-04[media] exynos4-is: Allow colorspace conversion at FIMC-LITESylwester Nawrocki
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: Sylwester Nawrocki <s.nawrocki@samsung.com> Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2013-04-04[media] exynos4-is: Add FIMC-IS ISP I2C bus driverSylwester Nawrocki
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.

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.

2013-04-04[media] V4L: Remove incorrect EXPORT_SYMBOL() usage at v4l2-of.cSylwester Nawrocki
v4l2_of_parse_parallel_bus() function is now static and EXPORT_SYMBOL() doesn't apply to it any more. Drop this meaningless statement, which was supposed to be done in the original merged patch. While at it, edit the copyright notice so it is sorted in both the v4l2-of.c and v4l2-of.h file in newest entries on top order, and state clearly I'm just the author of parts of the code, not the copyright owner.

2013-04-04[media] exynos4-is: Remove dependency on SYSCON for non-dt platformsSylwester Nawrocki
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.
