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).

Mediatek SOCs sysirq support controllable irq inverter for each GIC SPI
|
|
interrupt.

|
- interrupt-controller : Identifies the node as an interrupt controller
|
|
- #interrupt-cells : Use the same format as specified by GIC in arm,gic.txt.
|
|
- interrupt-parent: phandle of irq parent for sysirq. The parent must
|
|
use the same interrupt-cells format as GIC.
|
|
- reg: Physical base address of the intpol registers and length of memory
|
|
mapped region. Could be multiple bases here. Ex: mt6797 needs 2 reg, others
|
|
need 1.
|
|
|
|
Example:
|
|
sysirq: intpol-controller@10200620 {
|
|
compatible = "mediatek,mt6797-sysirq",
|
|
"mediatek,mt6577-sysirq";
|
|
interrupt-controller;
|
|
#interrupt-cells = <3>;
|
|
interrupt-parent = <&gic>;
|
|
reg = <0 0x10220620 0 0x20>,
|
|
<0 0x10220690 0 0x10>;
|
|
};
