* treewide: add MODULE_DEVICE_TABLE markersAhmad Fatoum2023-06-131-0/+1
| | | | | | | | | | | | | | | | Syncing device trees with Linux upstream can lead to breakage, when the device trees are switched to newer bindings, which are not yet supported in barebox. To make it easier to spot such issues, we want to start applying some heuristics to flag possibly problematic DT changes. One step towards being able to do that is to know what nodes barebox actually consumes. Most of the nodes have a compatible entry, which is matched by an array of of_device_id, so let's have MODULE_DEVICE_TABLE point at it for future extraction.

* ARM: tegra: Move mach header files to include/mach/tegraSascha Hauer2023-03-061-3/+3
| | | | | | | | | | Currently arch specific headers can be included with longer possible as there won't be a single mach anymore. Move all tegra specific header files to include/mach/tegra/ to prepare for multi-arch support. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Rename struct driver_d to driverSascha Hauer2023-01-101-1/+1
| | | | | | | | | | | The '_d' suffix was originally meant to distinguish barebox struct names from Linux struct names. struct driver doesn't exist in Linux, so we can rename it and remove the meaningless suffix.

* Rename struct device_d to deviceSascha Hauer2023-01-101-1/+1
| | | | | | | | | | | | | The '_d' suffix was originally introduced in case we want to import Linux struct device as a separate struct into barebox. Over time it became clear that this won't happen, instead barebox struct device_d is basically the same as Linux struct device. Rename the struct name accordingly to make porting Linux code easier.

* Rename device_d::device_node to device_d::of_nodeSascha Hauer2023-01-101-2/+2
| | | | | | | | | | | | | | | | | | | | Linux struct device has the member of_node for the device_node pointer. Rename this in barebox accordingly to minimize the necessary changes when porting Linux code. This was done with the semantic patch: @@ struct device_d E; @@ - E.device_node + E.of_node @@ struct device_d *E; @@ - E->device_node + E->of_node Plus some manual adjustments.

* treewide: Use driver macroSascha Hauer2020-09-291-5/+1
| | | | | | | We have several macros for a oneline driver registration. Add some missing and use them consistently where possible througout the tree. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* clk: migrate to SPDX-License-Identifier useAhmad Fatoum2020-04-151-12/+1
| | | | | | | | | | | | Some of these are a product of source sync with Linux, the other were done with macro assistance by searching for /later/, deleting license text, adding appropriate SPDX-License-Identifier and manual post-review. Devices without a license indicated where assumed GPL-2.0-only according with the project's license.
