1ARM Atmel SoCs (aka AT91)
2=========================

5Introduction
6------------
7This document gives useful information about the ARM Atmel SoCs that are
8currently supported in Linux Mainline (you know, the one on kernel.org).
9
10It is important to note that the Atmel | SMART ARM-based MPU product line is
11historically named "AT91" or "at91" throughout the Linux kernel development
12process even if this product prefix has completely disappeared from the
13official Atmel product name. Anyway, files, directories, git trees,
14git branches/tags and email subject always contain this "at91" sub-string.

94Linux kernel information
95------------------------
96Linux kernel mach directory: arch/arm/mach-at91
97MAINTAINERS entry is: "ARM/ATMEL AT91RM9200 AND AT91SAM ARM ARCHITECTURES"

100Device Tree for AT91 SoCs and boards
101------------------------------------
102All AT91 SoCs are converted to Device Tree. Since Linux 3.19, these products
103must use this method to boot the Linux kernel.
104
105Work In Progress statement:
106Device Tree files and Device Tree bindings that apply to AT91 SoCs and boards are
107considered as "Unstable". To be completely clear, any at91 binding can change at
108any time. So, be sure to use a Device Tree Binary and a Kernel Image generated from
109the same source tree.
110Please refer to the Documentation/devicetree/bindings/ABI.txt file for a
111definition of a "Stable" binding/ABI.
112This statement will be removed by AT91 MAINTAINERS when appropriate.
113
114Naming conventions and best practice:
115- SoCs Device Tree Source Include files are named after the official name of
116 the product (at91sam9g20.dtsi or sama5d33.dtsi for instance).
117- Device Tree Source Include files (.dtsi) are used to collect common nodes that can be
118 shared across SoCs or boards (sama5d3.dtsi or at91sam9x5cm.dtsi for instance).
119 When collecting nodes for a particular peripheral or topic, the identifier have to
120 be placed at the end of the file name, separated with a "_" (at91sam9x5_can.dtsi
121 or sama5d3_gmac.dtsi for example).
122- board Device Tree Source files (.dts) are prefixed by the string "at91-" so
123 that they can be identified easily. Note that some files are historical exceptions
124 to this rule (sama5d3[13456]ek.dts, usb_a9g20.dts or animeo_ip.dts for example).

6 * Functions to disable system interrupts from backup-powered peripherals.
7 *
8 * The RTC and RTT-peripherals are generally powered by backup power (VDDBU)
9 * and are not reset on wake-up, user, watchdog or software reset. This means
10 * that their interrupts may be enabled during early boot (e.g. after a user
11 * reset).
12 *
13 * As the RTC and RTT share the system-interrupt line with the PIT, an
14 * interrupt occurring before a handler has been installed would lead to the
15 * system interrupt being disabled and prevent the system from booting.
