| * soc: mediatek: Explicitly include correct DT includesRob Herring2023-08-125-5/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

A handful of drivers needed some adjustment to their includes as a result. - Refactor of_device.h to be used by bus drivers rather than various device drivers. This moves non-bus related functions out of of_device.h. The end goal is for of_platform.h and of_device.h to stop including each other. - Refactor open coded parsing of "ranges" in some bus drivers to use DT address parsing functions - Add some new address parsing functions of_property_read_reg(), of_range_count(), and of_range_to_resource() in preparation to convert more open coded parsing of DT addresses to use them. - Treewide clean-ups to use of_property_read_bool() and of_property_present() as appropriate.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MT8173 SoC has 64 MMSYS resets, split in two contiguous 32-bits registers, MMSYS_SW0_RST_B (0x140) and MMSYS_SW1_RST_B (0x144), as also stated in the downstream kernel for the Amazon Fire TV 2 (Sloane) in the ddp_reg.h header.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MT2701, MT2712 and MT8173 were relying on a "default" DDP I/O routing table, describing all of the possible connections between display block components: while this is definitely working it's suboptimal for the actual routing description, as we may be enabling outputs and inputs that are not needed, possibly impacting on actual DDP performance other than slightly prolonging boot times by having to parse a table that is bigger than needed. Seen that all of the other supported SoCs have got their own table and seen that a comment in mtk-mmsys.h explicitly mentions that the wanted way is to have one table per SoC, create a new routing table that is specifically tailored to MT8173 and, while at it, remove mentions to said SoC from the comment in mtk-mmsys.h.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that the mtk-cmdq.h header contains inline functions for cases in which the driver is not enabled (either module or built-in), we can safely go on with cleaning up ifdefs for CMDQ handling.
