This series adds support for the PXP found on the i.MX7D to the imx-pxp driver. The PXP on the i.MX7D has a few differences compared to the one on the i.MX6ULL. Especially, it has more processing blocks and slightly different multiplexers to route the data between the blocks. Therefore, the driver must configure a different data path depending on the platform. While the PXP has a version register, the reported version is the same on the i.MX6ULL and the i.MX7D. Therefore, we cannot use the version register to change the driver behavior, but have to use the device tree compatible. The driver still prints the found version to the log to help bringing up the PXP on further platforms. The patches are inspired by some earlier patches [0] by Laurent to add PXP support to the i.MX7d. Compared to the earlier patches, these patches add different behavior depending on the platform. Furthermore, the patches disable only the LUT block, but keep the rotator block enabled, as it may now be configured via the V4L2 rotate control. Patch 1 converts the dt-binding to yaml. Patches 2 to 5 cleanup and refactor the driver in preparation of handling different PXP versions. Patches 6 and 7 add the handling of different platforms and the i.MX7d specific configuration. Patch 8 adds the device tree node for the PXP to the i.MX7d device tree.
