In reply to Unturned3.
The second iteration splits the sun6i-csi rework into different commits instead of removing the current driver and adding a new one. Both of these iterations are now deprecated. The current series is split into 4 series (platform, mipi csi-2, csi rework, isp), with the mipi csi-2 series already merged for 6.0.
You can find the latest versions of the series on the linux media patchwork: https://patchwork.linuxtv.org/project/linux-media/list/?submitter=7413
