The companding block is an ISP processing block located at the front of the processing pipeline that performs data expansion, black level subtraction and data compression. It is found in the ISP8000Nano on the i.MX8MP, and not present in Rockchip versions of the ISP, that implement BLS in a dedicated block (not present in the ISP8000Nano) already supported by the driver. The first two patches start with preparatory work. Patch 1/5 refactors existing duplicate code to share a common function, that will also be used later in this series. Patch 2/5 then improves the ISP parameters extensible format handler by making it possible to condition support for particular ISP blocks based on device features. Support for the companding block follows in the next three patches. Patch 3/5 adds macros for the companding block registers, and patch 4/5 adds feature flags to differentiate between the dedicated BLS block and the companding block. Finally, patch 5/5 adds support for the companding block in the ISP parameters. The series is based on Jacopo's support for extensible parameters in the rkisp1 driver ("[PATCH v5 0/7] media: rkisp1: Implement support for extensible parameters", see [1]). Thanks to that work, adding support for a new ISP block in a backward compatible way is easy. I have pushed a branch to [2] that includes all the dependencies, on top of the media stage master branch.
