2018-05-25media: vsp1: Adapt entities to configure into a bodyKieran Bingham
Currently the entities store their configurations into a display list. Adapt this such that the code can be configured into a body directly, allowing greater flexibility and control of the content. All users of vsp1_dl_list_write() are removed in this process, thus it too is removed. A helper, vsp1_dl_list_get_body0() is provided to access the internal body0 from the display list.

2018-05-25media: vsp1: Refactor display list configure operationsKieran Bingham
The entities provide a single .configure operation which configures the object into the target display list, based on the vsp1_entity_params selection. Split the configure function into three parts, '.configure_stream()', '.configure_frame()', and '.configure_partition()' to facilitate splitting the configuration of each parameter class into separate display list bodies.

2018-05-17media: v4l: vsp1: Use SPDX license headersLaurent Pinchart
Adopt the SPDX license identifier headers to ease license compliance management. All files in the driver are licensed under the GPLv2+ except for the vsp1_regs.h file which is licensed under the GPLv2. This is likely an oversight, but fixing this requires contacting the copyright owners and is out of scope for this patch. While at it fix the file descriptions to match file names where copy and paste error occurred.

2018-05-04media: v4l: vsp1: Rename BRU to BRxLaurent Pinchart
Some VSP instances have two blending units named BRU (Blend/ROP Unit) and BRS (Blend/ROP Sub unit). The BRS is a smaller version of the BRU with only two inputs, but otherwise offers similar features and offers the same register interface. The BRU and BRS can be used exchangeably in VSP pipelines (provided no more than two inputs are needed). Due to historical reasons, the VSP1 driver implements support for both the BRU and BRS through objects named vsp1_bru. The code uses the name BRU to refer to either the BRU or the BRS, except in a few places where noted explicitly. This creates confusion. In an effort to avoid confusion, rename the vsp1_bru object and the corresponding API to vsp1_brx, and use BRx to refer to blend unit instances regardless of their type. The names BRU and BRS are retained where reference to a particular blend unit type is needed, as well as in hardware registers to stay close to the datasheet.
