Subject: [PATCH v2 00/15] staging: vc04_services: bcm2835-isp support
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.
