2018-05-05media: rcar-vin: remove generic gen3 compatible stringNiklas Söderlund1-1/+0
The compatible string "renesas,rcar-gen3-vin" was added before the Gen3 driver code was added but it's not possible to use. Each SoC in the Gen3 series require SoC specific knowledge in the driver to function. Remove it before it is added to any device tree descriptions.

2018-04-20media: rcar-vin: add Gen3 devicetree bindings documentationNiklas Söderlund1-12/+106
Document the devicetree bindings for the CSI-2 inputs available on Gen3. There is a need to add a custom property 'renesas,id' and to define which CSI-2 input is described in which endpoint under the port@1 node. This information is needed since there are a set of predefined routes between each VIN and CSI-2 block. This routing table will be kept inside the driver but in order for it to act on it it must know which VIN and CSI-2 is which.

Add compatible strings for r8a7743 and r8a7745. No driver change is needed as "renesas,rcar-gen2-vin" will activate the right code. However, it is good practice to document compatible strings for the specific SoC as this allows SoC specific changes to the driver if needed, in addition to document SoC support and therefore allow checkpatch.pl to validate compatible string values.

2016-04-13[media] soc_camera: rcar_vin: add device tree support for r8a7792Simon Horman1-0/+1
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.

2016-04-13[media] soc_camera: rcar_vin: add R-Car Gen 2 and 3 fallback compatibility stringsYoshihiro Kaneko1-2/+9
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.
