1 Atmel AT91 device tree bindings.
2 ================================
4 PIT Timer required properties:
5 - compatible: Should be "atmel,at91sam9260-pit"
6 - reg: Should contain registers location and length
7 - interrupts: Should contain interrupt for the PIT which is the IRQ line
8 shared across all System Controller members.
10 TC/TCLIB Timer required properties:
11 - compatible: Should be "atmel,<chip>-pit".
12 <chip> can be "at91rm9200" or "at91sam9x5"
13 - reg: Should contain registers location and length
14 - interrupts: Should contain all interrupts for the TC block
15 Note that you can specify several interrupt cells if the TC
16 block has one interrupt per channel.
20 One interrupt per TC block:
21 tcb0: timer@fff7c000 {
22 compatible = "atmel,at91rm9200-tcb";
23 reg = <0xfff7c000 0x100>;
27 One interrupt per TC channel in a TC block:
28 tcb1: timer@fffdc000 {
29 compatible = "atmel,at91rm9200-tcb";
30 reg = <0xfffdc000 0x100>;
31 interrupts = <26 4 27 4 28 4>;
34 RSTC Reset Controller required properties:
35 - compatible: Should be "atmel,<chip>-rstc".
36 <chip> can be "at91sam9260" or "at91sam9g45"
37 - reg: Should contain registers location and length
42 compatible = "atmel,at91sam9260-rstc";
43 reg = <0xfffffd00 0x10>;
46 RAMC SDRAM/DDR Controller required properties:
47 - compatible: Should be "atmel,at91sam9260-sdramc",
48 "atmel,at91sam9g45-ddramc",
49 - reg: Should contain registers location and length
50 For at91sam9263 and at91sam9g45 you must specify 2 entries.
54 ramc0: ramc@ffffe800 {
55 compatible = "atmel,at91sam9g45-ddramc";
56 reg = <0xffffe800 0x200>;
59 ramc0: ramc@ffffe400 {
60 compatible = "atmel,at91sam9g45-ddramc";
61 reg = <0xffffe400 0x200
65 SHDWC Shutdown Controller
68 - compatible: Should be "atmel,<chip>-shdwc".
69 <chip> can be "at91sam9260", "at91sam9rl" or "at91sam9x5".
70 - reg: Should contain registers location and length
73 - atmel,wakeup-mode: String, operation mode of the wakeup mode.
74 Supported values are: "none", "high", "low", "any".
75 - atmel,wakeup-counter: Counter on Wake-up 0 (between 0x0 and 0xf).
77 optional at91sam9260 properties:
78 - atmel,wakeup-rtt-timer: boolean to enable Real-time Timer Wake-up.
80 optional at91sam9rl properties:
81 - atmel,wakeup-rtc-timer: boolean to enable Real-time Clock Wake-up.
82 - atmel,wakeup-rtt-timer: boolean to enable Real-time Timer Wake-up.
84 optional at91sam9x5 properties:
85 - atmel,wakeup-rtc-timer: boolean to enable Real-time Clock Wake-up.
90 compatible = "atmel,at91sam9260-rstc";
91 reg = <0xfffffd00 0x10>;
