The commit 39793c69 "[media] mx2_camera: Convert it to platform driver" used module_platform_driver() to make code smaller, but since the driver used platform_driver_probe is more appropriate to use module_platform_driver_probe(). 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:

Before the camera ports can be used the pinmux needs to be configured properly. This patch adds a function to set the camera ports pinctrl to a default state within the media driver's probe(). The camera port(s) are then configured for the video bus operation. 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.

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. Signed-off-by:

It doesn't matter whether we start from the sensor of from the video node entity. Remove use of pipeline->subdevs array where possible, so we can partly drop dependency on struct fimc_pipeline in the fimc-lite module, which is also used by the exynos5-is driver. Also make sure we revert any media entity pipeline operations when vb2_streamon() function fails. Signed-off-by:
