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.

2017-09-20ARM: dts: zynq: Add generic compatible string for I2C EEPROMJavier Martinez Canillas
The at24 driver allows to register I2C EEPROM chips using different vendor and devices, but the I2C subsystem does not take the vendor into account when matching using the I2C table since it only has device entries. But when matching using an OF table, both the vendor and device has to be taken into account so the driver defines only a set of compatible strings using the "atmel" vendor as a generic fallback for compatible I2C devices. So add this generic fallback to the device node compatible string to make the device to match the driver using the OF device ID table.

2015-12-14ARM: dts: zynq: replace gpio-key,wakeup with wakeup-source propertySudeep Holla
Though the keyboard driver for GPIO buttons(gpio-keys) will continue to check for/support the legacy "gpio-key,wakeup" boolean property to enable gpio buttons as wakeup source, "wakeup-source" is the new standard binding. This patch replaces the legacy "gpio-key,wakeup" with the unified "wakeup-source" property in order to avoid any futher copy-paste duplication.
