2018-08-03media: vsp1: Provide support for extended command poolsKieran Bingham2-0/+196
VSPD and VSP-DL devices can provide extended display lists supporting extended command display list objects. These extended commands require their own dma memory areas for a header and body specific to the command type. Implement a command pool to allocate all necessary memory in a single DMA allocation to reduce pressure on the TLB, and provide convenient re-usable command objects for the entities to utilise.

2018-08-03media: vsp1: use kernel __packed for structuresKieran Bingham1-3/+3
The kernel provides a __packed definition to abstract away from the compiler specific attributes tag. Convert all packed structures in VSP1 to use it. The GCC documentation [0] describes this attribute as "the structure or union is placed to minimize the memory required". The Keil compiler documentation at [1] warns that the use of this attribute can cause a performance penalty in the event that the compiler can not deduce the allignment of each field. Careful examination of the object code generated both with and without this attribute shows that these structures are accessed identically and are not affected by any performance penalty. The structures are correctly aligned and padded to match the needs of the hardware already. This patch does not serve to make a decision as to the use of the attribute, but purely to clean up the code to use the kernel defined abstraction as per [2].

2018-08-02media: camss: Add basic runtime PM supportTodor Tomov6-6/+139
There is a PM domain for each of the VFE hardware modules. Add support for basic runtime PM support to be able to control the PM domains. When a PM domain needs to be powered on - a device link is created. When a PM domain needs to be powered off - its device link is removed. This allows separate and independent control of the PM domains. Suspend/Resume is still not supported.
