The DRM pipeline, as it runs in automatic restart mode, never sees the pipeline state set to VSP1_PIPELINE_STOPPING or VSP1_PIPELINE_STOPPED when running the frame end interrupt handler. We can thus skip the checks various checks in the handler and return immediately. Similarly the DRM frame end handler calls vsp1_pipeline_run() unnecessarily, as the state there is never VSP1_PIPELINE_STOPPED. Remove the function call and the frame end handler is it's now empty.

Commit 54b5a749 ("[media] v4l: vsp1: Use media entity enumeration interface") wasn't aligned with the driver coding style. Fix it by renaming the rval variable to ret. Furthermore shorten lines by accessing the media_device instance in a more straightforward fashion. Signed-off-by:

The VSP1 DRM API is declared in <media/vsp1.h>, not <linux/vsp1.h>. Fix it. This also reverts commit 18922936 ("[media] vsp1_drm.h: add missing prototypes") that added the same declarations in a different header file. Signed-off-by:

Add a new subdev operation to initialize a subdev pad config array, and a helper function to allocate and initialize the array. This can be used by bridge drivers to implement try format based on subdev pad operations. Signed-off-by:

All users of is_media_entity_v4l2_io() (the exynos4-is, omap3isp, davince_vpfe and omap4iss drivers and the v4l2-mc power management code) use the function to check whether entities are video_device instances, either to ensure they can cast the entity to a struct video_device, or to count the number of video nodes users. The purpose of the function is thus to identify whether the media entity instance is an instance of the video_device object, not to check whether it can perform I/O. Rename it accordingly, we will introduce a more specific is_media_entity_v4l2_io() check when needed. Signed-off-by:

Code that processes media entities can require knowledge of the structure type that embeds a particular media entity instance in order to cast the entity to the proper object type. This needs is shown by the presence of the is_media_entity_v4l2_io and is_media_entity_v4l2_subdev functions. The implementation of those two functions relies on the entity function field, which is both a wrong and an inefficient design, without even mentioning the maintenance issue involved in updating the functions every time a new entity function is added. Fix this by adding add an obj_type field to the media entity structure to carry the information. Signed-off-by:

Simply document new compatibility string. As a previous patch adds a generic R-Car Gen2 compatibility string there appears to be no need for a driver updates. By documenting this compat string it may be used in DTSs shipped, for example as part of ROMs. It must be used in conjunction with the Gen2 fallback compat string. At this time there are no known differences between the r8a7792 IP block and that implemented by the driver for the Gen2 fallback compat string. Thus there is no need to update the driver as the use of the Gen2 fallback compat string will activate the correct code in the current driver while leaving the option for r8a7792-specific driver code to be activated in an updated driver should the need arise.

Add fallback compatibility string for R-Car Gen 1 and 2. In the case of Renesas R-Car hardware we know that there are generations of SoCs, e.g. Gen 2 and 3. But beyond that it's unclear what the relationship between IP blocks might be. For example, I believe that r8a7790 is older than r8a7791 but that doesn't imply that the latter is a descendant of the former or vice versa. We can, however, by examining the documentation and behaviour of the hardware at run-time observe that the current driver implementation appears to be compatible with the IP blocks on SoCs within a given generation. For the above reasons and convenience when enabling new SoCs a per-generation fallback compatibility string scheme being adopted for drivers for Renesas SoCs. Signed-off-by:

A dependency on ARCH_SHMOBILE seems to be the best option for sh_mobile_ceu_camera: * For Super H based SoCs: sh_mobile_ceu is used on SH_AP325RXA, SH_ECOVEC, SH_KFR2R09, SH_MIGOR, and SH_7724_SOLUTION_ENGINE which depend on CPU_SUBTYPE_SH7722, CPU_SUBTYPE_SH7723, or CPU_SUBTYPE_SH7724 which all select ARCH_SHMOBILE. * For ARM Based SoCs: Since the removal of legacy (non-multiplatform) support this driver has not been used by any Renesas ARM based SoCs. The Renesas ARM based SoCs currently select ARCH_SHMOBILE, however, it is planned that this will no longer be the case. This is part of an ongoing process to migrate from ARCH_SHMOBILE to ARCH_RENESAS the motivation for which being that RENESAS seems to be a more appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.

The "handled" variable could be uninitialized if the interrupt_service_routine() call back hasn't been implimented or if it has been implemented but doesn't initialize "handled" to zero at the start.
