This series aims to upport bcm2835-isp from the RPi kernel. It is developed on top of staging-next which comprises many VC04 changes for it's de-staging. Hence, the merge of this driver is targeted when VC04 is de-staged completely (which I have been pushing), but it can be helped getting reviewed meanwhile. Hence, the reason for posting the series. Patch (01-02)/15 adds a new driver named vc-sm-cma to handle memory sharing with the VC4 VPU. Patch 03/15 adds a small extension to videobuf2 to allow exporting as a dma_buf instead of a file-descriptor. Patch (04-05)/15 adds a couple of improvements/support for bcm2835-isp(event callback and zero-copy) to vchiq-mmal. Patch (06-10)/15 adds the core bcm2835-isp driver along with headers and format defintions. 09/15 is a standalone patch which can be merged independently I believe. Patch (11-12)/15 deals with the colorspace support. Patch 13/15 allows multiple instances of the ISP. Patch 14/15 adds a admin-guide document on bcm2835-isp. Patch 15/15 deals with driver registeration.
since this is V2, i couldn't find a changelog? The first one was one year ago, so it's very hard to remember. In such a case a link to the last version is also helpful. Recently i saw you have a Github account. For such a complex series it's also very helpful to provide a link to a working test branch with this series applied. It's not a must, but appreciated. Best regards
