Richard Marko	6c9df40a4b	nixos/device-tree: improve overlays support ... Now allows applying external overlays either in form of .dts file, literal dts context added to store or precompiled .dtbo. If overlays are defined, kernel device-trees are compiled with '-@' so the .dtb files contain symbols which we can reference in our overlays. Since `fdtoverlay` doesn't respect `/ compatible` by itself we query compatible strings of both `dtb` and `dtbo(verlay)` and apply only if latter is substring of the former. Also adds support for filtering .dtb files (as there are now nearly 1k dtbs).

Florian Klink	387f3b58d2	hardware.deviceTree: add name ... This can be used to explicitly specify a specific dtb file, relative to the dtb base. Update the generic-extlinux-compatible module to make use of this option.	2020-06-21 13:48:22 +02:00
Florian Klink	43424688db	nixos/deviceTree: fix description ... hardware.deviceTree.base points to a path, not a package (and also if of types.path) It defaults to ${config.boot.kernelPackages.kernel}/dtbs.	2020-06-21 10:39:10 +02:00
Gaelan	4ed7e23636	nixos/device-tree: fix package name in examples ... deviceTree_rpi got renamed to device-tree_rpi a while back, so this updates the examples to reflect that.	2020-05-10 20:13:54 +02:00
Kai Wohlfahrt	28cf80acf8	nixos/hardware.deviceTree: Move things around ... In response to comments, create a sub-folder for deviceTree packages (starting with rpi), and a top-level package for helpers.	2019-08-07 13:51:22 +01:00
Kai Wohlfahrt	dd0a951279	nixos/hardware.deviceTree: new module ... Add support for custom device-tree files, and applying overlays to them. This is useful for supporting non-discoverable hardware, such as sensors attached to GPIO pins on a Raspberry Pi.	2019-08-07 13:51:22 +01:00
