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).

PXA3xx NAND DT bindings
|
|
|
|
Required properties:
|
|
|
|
- compatible: Should be set to one of the following:
|
|
marvell,pxa3xx-nand
|
|
marvell,armada370-nand
|
|
- reg: The register base for the controller
|
|
- interrupts: The interrupt to map
|
|
- #address-cells: Set to <1> if the node includes partitions
|
|
|
|
Optional properties:
|
|
|
|
- dmas: dma data channel, see dma.txt binding doc
|
|
- marvell,nand-enable-arbiter: Set to enable the bus arbiter
|
|
- marvell,nand-keep-config: Set to keep the NAND controller config as set
|
|
by the bootloader
|
|
- num-cs: Number of chipselect lines to use
|
|
- nand-on-flash-bbt: boolean to enable on flash bbt option if
|
|
not present false
|
|
- nand-ecc-strength: number of bits to correct per ECC step
|
|
- nand-ecc-step-size: number of data bytes covered by a single ECC step
|
|
|
|
The following ECC strength and step size are currently supported:
|
|
|
|
- nand-ecc-strength = <1>, nand-ecc-step-size = <512>
|
|
- nand-ecc-strength = <4>, nand-ecc-step-size = <512>
|
|
- nand-ecc-strength = <8>, nand-ecc-step-size = <512>
|
|
|
|
Example:
|
|
|
|
nand0: nand@43100000 {
|
|
compatible = "marvell,pxa3xx-nand";
|
|
reg = <0x43100000 90>;
|
|
interrupts = <45>;
|
|
dmas = <&pdma 97 0>;
|
|
dma-names = "data";
|
|
#address-cells = <1>;
|
|
|
|
marvell,nand-enable-arbiter;
|
|
marvell,nand-keep-config;
|
|
num-cs = <1>;
|
|
|
|
/* partitions (optional) */
|
|
};
