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.

2019-12-10ARM: dts: at91: Reenable UART TX pull-upsIngo van Lil
Pull-ups for SAM9 UART/USART TX lines were disabled in a previous commit. However, several chips in the SAM9 family require pull-ups to prevent the TX lines from falling (and causing an endless break condition) when the transceiver is disabled. From the SAM9G20 datasheet, 32.5.1: "To prevent the TXD line from falling when the USART is disabled, the use of an internal pull up is mandatory.". This commit reenables the pull-ups for all chips having that sentence in their datasheets.

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.
