* treewide: switch regmap.h include to linux/regmap.hAhmad Fatoum2023-10-261-1/+1
| | | | | | | | | | | | | | | Now that there are no longer any users of regmap.h in headers, let's switch all users in the source files to linux/regmap.h. That way, the only users of regmap.h whether directly or indirectly will be out-of-tree code, which will fail with an error if they are dependent on the old semantics of regmap_bulk_read and regmap_bulk_write. After a transitory period, we can then drop regmap.h.

* memory: Add driver for FMC2 External Bus Interface on STM32MP SoCsAlexander Shiyan2023-09-043-0/+1148
| | | | | | | | | This adds support for FMC2 External Bus Interface on STM32MP SoCs. The original source is taken from linux-6.4.

* treewide: add MODULE_DEVICE_TABLE markersAhmad Fatoum2023-06-132-0/+2
| | | | | | | | | | | | | | | | 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.

* memory: add Atmel EBI driverAhmad Fatoum2023-01-183-0/+629
| | | | | | | | | | | | | This driver is used to configure the EBI (external bus interface) when the device-tree is used. This bus supports NANDs, external Ethernet controller, SRAMs, ATA devices, etc. We import it from Linux in barebox in preparation for importing a newer state of the Atmel NAND controller driver.

* 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.
