Since Linux 3.19, these products -must use this method to boot the Linux kernel. - -Work In Progress statement: -Device Tree files and Device Tree bindings that apply to AT91 SoCs and boards are -considered as "Unstable". To be completely clear, any at91 binding can change at -any time. So, be sure to use a Device Tree Binary and a Kernel Image generated from -the same source tree. -Please refer to the Documentation/devicetree/bindings/ABI.txt file for a -definition of a "Stable" binding/ABI. -This statement will be removed by AT91 MAINTAINERS when appropriate. - -Naming conventions and best practice: - -- SoCs Device Tree Source Include files are named after the official name of - the product (at91sam9g20.dtsi or sama5d33.dtsi for instance). -- Device Tree Source Include files (.dtsi) are used to collect common nodes that can be - shared across SoCs or boards (sama5d3.dtsi or at91sam9x5cm.dtsi for instance). - When collecting nodes for a particular peripheral or topic, the identifier have to - be placed at the end of the file name, separated with a "_" (at91sam9x5_can.dtsi - or sama5d3_gmac.dtsi for example). -- board Device Tree Source files (.dts) are prefixed by the string "at91-" so - that they can be identified easily. Note that some files are historical exceptions - to this rule (sama5d3[13456]ek.dts, usb_a9g20.dts or animeo_ip.dts for example). |
