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.

2019-08-23ARM: dts: sunxi: Add mdio bus sub-node to GMACChen-Yu Tsai
The DWMAC binding never supported having the Ethernet PHY node as a direct child to the controller, nor did it support the "phy" property as a way to specify which Ethernet PHY to use. What seemed to work was simply the implementation ignoring the "phy" property and instead probing all addresses on the MDIO bus and using the first available one. The recent switch from "phy" to "phy-handle" breaks the assumptions of the implementation, and does not match what the binding requires. The binding requires that if an MDIO bus is described, it shall be a sub-node with the "snps,dwmac-mdio" compatible string. Add a device node for the MDIO bus, and move the Ethernet PHY node under it. Also fix up the #address-cells and #size-cells properties where needed.

So far we've enabled pull-up and pull-down resistors on GPIOs using a pinctrl node. Now that the GPIO binding allows for a flag to declare this, let's switch to it. This brings us closer to removing all the GPIO pinctrl nodes, which will in turn allow us to switch the pinctrl strict mode on.

2018-11-28ARM: dts: sun7i: Remove underscores from nodes namesMaxime Ripard
Some GPIO pinctrl nodes cannot be easily removed, because they would also change the pin configuration, for example to add a pull resistor or change the current delivered by the pin. Those nodes still have underscores and unit-addresses in their node names in our DTs, so adjust their name to remove the warnings. Use that occasion to also fix some poorly chosen node-names.

2018-11-28ARM: dts: sun7i: Change pinctrl nodes to avoid warningMaxime Ripard
All our pinctrl nodes were using a node name convention with a unit-address to differentiate the different muxing options. However, since those nodes didn't have a reg property, they were generating warnings in DTC. In order to accomodate for this, convert the old nodes to the syntax we've been using for the new SoCs, including removing the letter suffix of the node labels to the bank of those pins to make things more readable.

2018-11-28ARM: dts: sun7i: Change LRADC node names to avoid warningsMaxime Ripard
One of the usage of the LRADC is to implement buttons. The bindings define that we should have one subnode per button, with their associated voltage as a property. However, there was no reg property but we still used the voltage associated to the button as the unit-address, which eventually generated warnings in DTC.

2015-05-10ARM: sunxi: dt: Split the SPI pinctrl groupsMaxime Ripard
The pinctrl groups for SPI until now were also adding the chip selects in the SPI pinctrl group. This was causing a few issues, since a board was forced to use a random number of chipselects, even though it might use one of these chip selects for another pin. The number of chipselects defined was also not the same from one group to another because of different needs at the time these groups have been introduced, resulting in no clear view from the board DTS on what exactly is being muxed, which even might change in the future. Solve this by creating different pinctrl groups for the chipselects and the standard SPI pins (CLK, MOSI and MISO) so that we fix both issues.
