* 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: omap: Move mach header files to include/mach/omapSascha Hauer2023-03-061-2/+2
| | | | | | | | | | Currently arch specific headers can be included with longer possible as there won't be a single mach anymore. Move all omap specific header files to include/mach/omap/ 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 Hauer2023-01-101-3/+3
| | | | | | | | | | | | | 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.

* mci: omap: add new am335x and am437x SDHCI specific compatiblesAhmad Fatoum2020-07-111-0/+6
| | | | | | | | | | | | | | For a while now, Linux has had a sdhci-omap driver for TI's OMAP SoCs making use of the SDHCI core library. This was in addition to the older omap-hsmmc driver, which didn't. Linux commit 0b4edf11187 ("ARM: dts: Move am33xx and am43xx mmc nodes to sdhci-omap driver") changes the device tree compatible of the mmc nodes on the am33xx and am43xx SoCs away from the omap-hsmmc to the SDHCI driver. Add the new compatibles, so we aren't broken by the change. Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* of: use 'const void *' for struct of_device_id.dataAntony Pavlov2015-04-301-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 2011 barebox' of_device_id struct uses unsigned long type for data field: struct of_device_id { char *compatible; unsigned long data; }; Almost always struct of_device_id.data field are used as pointer and need 'unsigned long' casting. E.g. see 'git grep -A 4 of_device_id drivers/' output: drivers/ata/sata-imx.c:static __maybe_unused struct of_device_id imx_sata_dt_ids[] = { drivers/ata/sata-imx.c- { drivers/ata/sata-imx.c- .compatible = "fsl,imx6q-ahci", drivers/ata/sata-imx.c- .data = (unsigned long)&data_imx6, drivers/ata/sata-imx.c- }, { Here is of_device_id struct in linux kernel v4.0: struct of_device_id { char name[32]; char type[32]; char compatible[128]; const void *data; }; Changing of_device_id.data type to 'const void *data' will increase barebox' linux kernel compatibility and decrease number of 'unsigned long' casts.
