2023-06-21ARM: dts: Move .dts files to vendor sub-directoriesRob Herring
The arm dts directory has grown to 1559 boards which makes it a bit unwieldy to maintain and use. Past attempts stalled out due to plans to move .dts files out of the kernel tree. Doing that is no longer planned (any time soon at least), so let's go ahead and group .dts files by vendors. This move aligns arm with arm64 .dts file structure. There's no change to dtbs_install as the flat structure is maintained on install. The naming of vendor directories is roughly in this order of preference: - Matching original and current SoC vendor prefix/name (e.g. ti, qcom) - Current vendor prefix/name if still actively sold (SoCs which have been aquired) (e.g. nxp/imx) - Existing platform name for older platforms not sold/maintained by any company (e.g. gemini, nspire) The whole move was scripted with the exception of MAINTAINERS and a few makefile fixups.

Add support for bxcan (Basic eXtended CAN controller) to STM32F429.

This means that the secondary CAN can't be used without the primary CAN.

2022-02-07ARM: dts: stm32: remove timer5 duplicate unit-address on stm32f4 seriesFabrice Gasnier
Remove the following warnings seen when building with W=1. Warning (unique_unit_address): /soc/timer@40000c00: duplicate unit-address (also used in node /soc/timers@40000c00) This approach is based on some discussions[1], to restructure the dtsi and dts files. Timer5 is enabled by default on stm32f4 series, to act as clockevent. In order to get rid of the W=1 warning, and be compliant with dt-schemas (e.g. dtbs_check): - In stm32f429.dtsi: . Keep the more complete timers5 description . Remove the most simple timer5 node that is duplicate - In each board: . adopt "st,stm32-timer" compatible for timers5, also add the interrupt . use /delete-property/ and /delete-node/ so the it matches the clockevent bindings Note: all this is done in one shot (e.g. not split) to keep clockevent functionality.

2022-02-07ARM: dts: stm32: remove some timer duplicate unit-address on stm32f4 seriesFabrice Gasnier
Several unused "timer" are duplicate nodes of "timers" nodes. There are two dt-schemas: - timer/st,stm32-timer.yaml: A timer is needed on STM32F4 series, on all boards, to act as clockevent. - mfd/st,stm32-timers.yaml: Timers can be used for other purpose. By default, timer5 is left enabled to be used as clockevent. Remove all other timer clockevent nodes that are currently unused and duplicated. This removes several messages: Warning (unique_unit_address): /soc/timer@.. duplicate unit-address (also used in node /soc/timers@...)

2019-01-30ARM: dts: Kill off skeleton{64}.dtsiRob Herring
Remove the usage of skeleton.dtsi in the remaining dts files. It was deprecated since commit 9c0da3cc61f1 ("ARM: dts: explicitly mark skeleton.dtsi as deprecated"). This will make adding a unit-address to memory nodes easier. The main tricky part to removing skeleton.dtsi is we could end up with no /memory node at all when a bootloader depends on one being present. I hacked up dtc to check for this condition.
