205 Device Tree for AT91 SoCs and boards
206 ------------------------------------
207 All AT91 SoCs are converted to Device Tree. Si
208 must use this method to boot the Linux kernel.
209
210 Work In Progress statement:
211 Device Tree files and Device Tree bindings tha
212 considered as "Unstable". To be completely cle
213 any time. So, be sure to use a Device Tree Bin
214 the same source tree.
215 Please refer to the Documentation/devicetree/b
216 definition of a "Stable" binding/ABI.
217 This statement will be removed by AT91 MAINTAI
218
219 Naming conventions and best practice:
220
221 - SoCs Device Tree Source Include files are na
222 the product (at91sam9g20.dtsi or sama5d33.dt
223 - Device Tree Source Include files (.dtsi) are
224 shared across SoCs or boards (sama5d3.dtsi o
225 When collecting nodes for a particular perip
226 be placed at the end of the file name, separ
227 or sama5d3_gmac.dtsi for example).
228 - board Device Tree Source files (.dts) are pr
229 that they can be identified easily. Note tha
230 to this rule (sama5d3[13456]ek.dts, usb_a9g2
