- IBM Akebono board device tree
- =============================
- The IBM Akebono board is a development board for the PPC476GTR SoC.
- 0) The root node
- Required properties:
- - model : "ibm,akebono".
- - compatible : "ibm,akebono" , "ibm,476gtr".
- 1.a) The Secure Digital Host Controller Interface (SDHCI) node
- Represent the Secure Digital Host Controller Interfaces.
- Required properties:
- - compatible : should be "ibm,476gtr-sdhci","generic-sdhci".
- - reg : should contain the SDHCI registers location and length.
- - interrupt-parent : a phandle for the interrupt controller.
- - interrupts : should contain the SDHCI interrupt.
- 1.b) The Advanced Host Controller Interface (AHCI) SATA node
- Represents the advanced host controller SATA interface.
- Required properties:
- - compatible : should be "ibm,476gtr-ahci".
