threeeye bc1d038eac REVVL 6 Pro kernel bring-up: full working tree snapshot (2026-09-12)
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).

Lantiq XWAY SoC FPI BUS binding
============================
-------------------------------------------------------------------------------
Required properties:
- compatible : Should be one of
"lantiq,xrx200-fpi"
- reg : The address and length of the XBAR
configuration register.
Address and length of the FPI bus itself.
- lantiq,rcu : A phandle to the RCU syscon
- lantiq,offset-endianness : Offset of the endianness configuration
register
-------------------------------------------------------------------------------
Example for the FPI on the xrx200 SoCs:
fpi@10000000 {
compatible = "lantiq,xrx200-fpi";
ranges = <0x0 0x10000000 0xf000000>;
reg = <0x1f400000 0x1000>,
<0x10000000 0xf000000>;
lantiq,rcu = <&rcu0>;
lantiq,offset-endianness = <0x4c>;
#address-cells = <1>;
#size-cells = <1>;
gptu@e100a00 {
......
};
};
