2013-04-14[media] exynos4-is: Make fimc-lite independent of struct fimc_sensor_infoSylwester Nawrocki4-43/+54
Make the sensor subdevs host_data hold a pointer to struct fimc_source_info, which is defined in the driver's public header, rather than a pointer to struct fimc_sensor_info which is specific to exynos4-is media device driver. The purpose of this change is to allow easier reuse of the fimc-lite module in the exynos5-is driver, which should similarly store a pointer to struct fimc_source_info instance in the sensor's subdev host_data.

2013-04-14[media] exynos4-is: Make fimc-lite independent of the pipeline->subdevs arraySylwester Nawrocki1-29/+28
Get the sensor subdev by walking media graph in both cases: when the device is used as a subdev only and through video node. This allows to not dereference the pipeline->subdevs[] array and makes the module more generic and easier to re-use in other media driver.

2013-04-04[media] exynos4-is: Correct input DMA YUV order configurationSylwester Nawrocki3-17/+18
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 Nawrocki4-33/+59
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 Nawrocki2-0/+144
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 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.

2013-03-31[media] s5p-fimc: Add device tree based sensors registrationSylwester Nawrocki1-25/+213
The sensor (I2C and/or SPI client) devices are instantiated by their corresponding control bus drivers. Since the I2C client's master clock is often provided by a video bus receiver (host interface) or other than I2C/SPI controller device, the drivers of those client devices are not accessing hardware in their driver's probe() callback. Instead, after enabling clock, the host driver calls back into a sub-device when it wants to activate them. This pattern is used by some in-tree drivers and this patch also uses it for DT case. This patch is intended as a first step for adding device tree support to the S5P/Exynos SoC camera drivers. The second one is adding support for asynchronous sub-devices registration and clock control from sub-device driver level. The bindings shall not change when asynchronous probing support is added.

2013-03-31[media] s5p-fimc: Add device tree support for the media device driverSylwester Nawrocki3-17/+97
This patch adds changes required for the main camera media device driver corresponding to the top level 'camera' device node. The drivers of devices corresponding to child nodes of the 'camera' node are looked up and and registered as sub-devices to the top level driver. The main driver's probing is deferred if any of the sub-device drivers is not yet initialized and ready.

2013-03-31[media] s5p-fimc: Add device tree support for FIMC-LITE device driverSylwester Nawrocki1-18/+45
This patch adds the device tree support for FIMC-LITE device driver. The bindings include compatible property for the Exynos5 SoC series, however the actual implementation for these SoCs will be added in a separate patch.

2013-03-31[media] s5p-fimc: Add device tree support for FIMC device driverSylwester Nawrocki5-114/+159
This patch adds device tree support for FIMC driver on S5PV210 and Exynos4 SoCs. The FIMC IP block's features and quirks encoded statically in the driver are now parsed from the device tree. Once all relevant platforms are converted to device tree based booting the FIMC variant data structures will all be removed from the driver.

2013-03-31[media] s5p-csis: Add device tree supportSylwester Nawrocki2-35/+121
This patch support for binding the driver to the MIPI-CSIS devices instantiated from device tree and parsing the SoC and board specific properties. The MIPI CSI-2 channel is determined by the value of reg property placed in csis' port subnode.
