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.

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.

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.

In multiplatform configurations, we cannot include headers provided by only the exynos platform. Fortunately a number of drivers that include those headers do not actually need them, so we can just remove the inclusions. Signed-off-by:

As reported by Dan Carpenter: FYI, there are new smatch warnings show up in tree: git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next master head: da17d7bda957ae4697b6abc0793f74fb9b50b58f commit: 4c3bdb5e [media] siano: better debug send/receive messages drivers/media/common/siano/smscoreapi.c:396 smscore_translate_msg() error: buffer overflow 'siano_msgs' 401 <= 401 While it is almost impossible for this error to happen in practice, as it would require the siano's firmware to return an special invalid answer to a message request, fixing it is trivial. So, let's do it. Reported-by:

OTOH the initialization of ret in m920x_init is needless, the function returns with an error as soon as an error happens, so the last return can only be a success and we can hard-code 0 there.

The s5p-fimc directory now contains drivers for multiple IP blocks found in multiple Samsung application processors. This includes FIMC (CAMIF), MIPI CSIS and FIMC LITE. FIMC-IS (Imaging Subsystem) driver is going to be put into same directory. Hence we rename it to exynos4-is as s5p-fimc was only relevant for early version of this driver, when it only supported FIMC IP block. The imaging subsystem drivers for Exynos4 SoC series and S5PV210 will be included in drivers/media/platform/exynos4-is directory, with some modules shared with exynos5 series, while the rest of exynos5 specific modules will find their home in drivers/media/platform/exynos5-is.

Since the FIMC-IS firmware communicates with an image sensor directly through the ISP I2C bus controllers the sub-devices power supplies cannot be simply enabled from left to right or disabled from right to left along the processing pipeline. Thus a subdev index to call s_power() on is looked up from a table, rather than doing the op call based on increasing/decreasing indexes. Signed-off-by:

In configurations where FIMC-LITE is used to capture image signal from an external sensor only we need to ensure one of FIMC devices is in active power state and the "fimc" gate clock is enabled. Otherwise the CAMCLK clock output signal will be masked off preventing an external sensor's operation. This affect processing pipelines like: - sensor -> FIMC-LITE -> memory - sensor -> MIPI-CSIS -> FIMC-LITE -> memory Signed-off-by:

A second sink pad is added to each FIMC.N subdev that will be used to link it to the FIMC-IS-ISP subdev. Only V4L2_MBUS_FMT_YUV10_1X30 format is supported at this pad (FIMC_SD_PAD_SINK_FIFO). The routine checking for mismatch in the image formats at sides of the links is updated to account for the fact FIMC.X subdevs now have sink pads at the pad indexes 0, 1 and source pad at pad index 2. If link to FIMC.X pad 1 is activated we switch FIMC input data bus type to the ISP Writeback. Only a single active link to FIMC.X pad 0 or 1 will be allowed at any time. Signed-off-by:

We cannot assume that the passed entity the fimc_pipeline_prepare() function is supposed to start the media graph traversal from will always have its sink pad at pad index 0. Find the starting media entity's sink pad by iterating over its all pads and checking the pad flags. This ensures proper handling of FIMC, FIMC-LITE and FIMC-IS-ISP subdevs that have more than one sink and one source pad. Signed-off-by:

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.

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.
