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).

FLCTL NAND controller
|
|
|
|
Required properties:
|
|
- compatible : "renesas,shmobile-flctl-sh7372"
|
|
- reg : Address range of the FLCTL
|
|
- interrupts : flste IRQ number
|
|
- nand-bus-width : bus width to NAND chip
|
|
|
|
Optional properties:
|
|
- dmas: DMA specifier(s)
|
|
- dma-names: name for each DMA specifier. Valid names are
|
|
"data_tx", "data_rx", "ecc_tx", "ecc_rx"
|
|
|
|
The DMA fields are not used yet in the driver but are listed here for
|
|
completing the bindings.
|
|
|
|
The device tree may optionally contain sub-nodes describing partitions of the
|
|
address space. See partition.txt for more detail.
|
|
|
|
Example:
|
|
|
|
flctl@e6a30000 {
|
|
#address-cells = <1>;
|
|
#size-cells = <1>;
|
|
compatible = "renesas,shmobile-flctl-sh7372";
|
|
reg = <0xe6a30000 0x100>;
|
|
interrupts = <0x0d80>;
|
|
|
|
nand-bus-width = <16>;
|
|
|
|
dmas = <&dmac 1 /* data_tx */
|
|
&dmac 2;> /* data_rx */
|
|
dma-names = "data_tx", "data_rx";
|
|
|
|
system@0 {
|
|
label = "system";
|
|
reg = <0x0 0x8000000>;

};

|
userdata@8000000 {
|
|
label = "userdata";
|
|
reg = <0x8000000 0x10000000>;
|
|
};
|
|
|
|
cache@18000000 {
|
|
label = "cache";
|
|
reg = <0x18000000 0x8000000>;
|
|
};
