The different resources required for different camss soc versions are split in to two groups: 1. Camss device related. In this group are all resources described in the device tree, clocks, regulators etc. 2. Sub-device specific resources. In the initialization of the each sub-device, the version of camss is passed. Based on this version the sub-device adds: hw layer support, per pad formats, number of dma's etc. The code for "1" group lives in camss.c. However the "2" group is spread across all sub-device implementations including video device. This kind of separation is not very convenient when adding new camss soc version. The reason is that you need to add support in all sub-device implementations. There were some improvements in this direction where some of the hw version related definitions were moved in to the "1". One example is attaching of the hw operations. This series aim to improve the things more and add additional definitions in to the "1". What is included: - Remove all format definitions from camss video. The will be passed by the parent sub-device - Make camss generic format definition mapping, containing mbus to v4l2 mapping, mbus bpp and other required fields used by the sub-device and video node. - Add per sub-device type union in the resources, different sub-devices are using different resources, as an example: is_lite flag. - Move camss link operation in to the resources. Currently one function supports different topologies depending of the number of devices. As hw version support increases this is not good way of supporting different topologies. - Add parent device ops in to the resources. This resolves inter-dependencies of vfe and csid. Csid requests the clocks regulators etc from parent device instead calling directly vfe functions. - Some cleanups in csid code for split the configuration of RX and testgen and RDI. Changes in V4: - Updated first patch with once posted by Bryan O'Donoghue <bryan.odonoghue@xxxxxxxxxx> for adding missing csiphy types in 8280xp resources. - Incorporate only cosmetic changes pointed by Vladimir Zapolskiy <vladimir.zapolskiy@xxxxxxxxxx> as agreed. - Add Reviewed-by and Tested-by tags form Bryan O'Donoghue <bryan.odonoghue@xxxxxxxxxx> Changes in V3: - Incorporate missing changes in resources reported and fixed by Bryan O'Donoghue <bryan.odonoghue@xxxxxxxxxx> taken from the branch: https://git.codelinaro.org/bryan.odonoghue/kernel/-/tree/sc8280xp-6.9-rc1-camss-resource-change-verification?ref_type=heads - Added missing signed-off to the changes submitted by me. Changes in V2: - Rebased on top of sc8280xp v6. - The change "Designate lite subdevices in resources" was dropped, it was already merged in previous series.
