2 IBM Akebono board device tree
3 =============================
5 The IBM Akebono board is a development board for the PPC476GTR SoC.
11 - model : "ibm,akebono".
12 - compatible : "ibm,akebono" , "ibm,476gtr".
14 1.a) The Secure Digital Host Controller Interface (SDHCI) node
16 Represent the Secure Digital Host Controller Interfaces.
20 - compatible : should be "ibm,476gtr-sdhci","generic-sdhci".
21 - reg : should contain the SDHCI registers location and length.
22 - interrupt-parent : a phandle for the interrupt controller.
23 - interrupts : should contain the SDHCI interrupt.
25 1.b) The Advanced Host Controller Interface (AHCI) SATA node
27 Represents the advanced host controller SATA interface.
31 - compatible : should be "ibm,476gtr-ahci".
32 - reg : should contain the AHCI registers location and length.
33 - interrupt-parent : a phandle for the interrupt controller.
34 - interrupts : should contain the AHCI interrupt.
38 The Akebono board stores some board information such as the revision
39 number in an FPGA which is represented by this node.
43 - compatible : should be "ibm,akebono-fpga".
44 - reg : should contain the FPGA registers location and length.
48 The Akebono board has an Atmel AVR microprocessor attached to the I2C
49 bus as a power controller for the board.
53 - compatible : should be "ibm,akebono-avr".
54 - reg : should contain the I2C bus address for the AVR.
