Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote).

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".
|
|
- reg : should contain the AHCI registers location and length.
|
|
- interrupt-parent : a phandle for the interrupt controller.
|
|
- interrupts : should contain the AHCI interrupt.
|
|
|
|
1.c) The FPGA node
|
|
|
|
The Akebono board stores some board information such as the revision
|
|
number in an FPGA which is represented by this node.
|
|
|
|
Required properties:
|
|
|
|
- compatible : should be "ibm,akebono-fpga".
|
|
- reg : should contain the FPGA registers location and length.
|
|
|
|
1.d) The AVR node
|
|
|
|
The Akebono board has an Atmel AVR microprocessor attached to the I2C
|
|
bus as a power controller for the board.
|
|
|
|
Required properties:
|
|
|
|
- compatible : should be "ibm,akebono-avr".
|
|
- reg : should contain the I2C bus address for the AVR.
