media: staging: imgu: make imgu work on low frequency for low input Currently, imgu is working on 450MHz for all cases, however in some cases (input frame less than 2048x1152), the imgu did not need work in high frequency. This patch make imgu work on 200MHz if the imgu input frame is less than 2048x1152 to save power.

media: ipu3-imgu: Prefix functions with imgu_* instead of ipu3_* This addresses the below TODO item, no function related changes: - Prefix imgu for all public APIs, i.e. change ipu3_v4l2_register() to imgu_v4l2_register(). (Sakari) The changes were obtained by applying the following perl script to driver code under drivers/staging/media/ipu3/. perl -pi.back -e 's/ipu3_(?!uapi)/imgu_/g;' Signed-off-by: Yong Zhi <yong.zhi@intel.com> Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

media: staging/intel-ipu3: Add dual pipe support This patch adds support to run dual pipes simultaneously. A private ioctl to configure the pipe mode (video or still) is also implemented. IPU3 hardware supports a maximum of 2 streams per pipe. With the support of dual pipes, more than 2 stream outputs can be achieved. This helps to support advanced camera features like Continuous View Finder (CVF) and Snapshot During Video(SDV). Extend ipu3 IMGU driver to support dual pipes 1. Extend current IMGU device to contain 2 groups of video nodes and 2 subdevs 2. Extend current css to support 2 pipeline and make CSS APIs to support 2 pipe 3. Add a v4l2 ctrl to allow user to specify the mode of the pipe 4. Check media pipeline link status to get enabled pipes Signed-off-by: Bingbu Cao <bingbu.cao@intel.com> Signed-off-by: Tian Shu Qiu <tian.shu.qiu@intel.com> Signed-off-by: Yong Zhi <yong.zhi@intel.com> Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
