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).

STMicroelectronics STi System Configuration Controlled IRQs
-----------------------------------------------------------
On STi based systems; External, CTI (Core Sight), PMU (Performance Management),
and PL310 L2 Cache IRQs are controlled using System Configuration registers.
This driver is used to unmask them prior to use.
Required properties:
- compatible : Should be set to one of:
"st,stih415-irq-syscfg"
"st,stih416-irq-syscfg"
"st,stih407-irq-syscfg"
"st,stid127-irq-syscfg"
- st,syscfg : Phandle to Cortex-A9 IRQ system config registers
- st,irq-device : Array of IRQs to enable - should be 2 in length
- st,fiq-device : Array of FIQs to enable - should be 2 in length
Optional properties:
- st,invert-ext : External IRQs can be inverted at will. This property inverts
these IRQs using bitwise logic. A number of defines have been
provided for convenience:
ST_IRQ_SYSCFG_EXT_1_INV
ST_IRQ_SYSCFG_EXT_2_INV
ST_IRQ_SYSCFG_EXT_3_INV
Example:
irq-syscfg {
compatible = "st,stih416-irq-syscfg";
st,syscfg = <&syscfg_cpu>;
st,irq-device = <ST_IRQ_SYSCFG_PMU_0>,
<ST_IRQ_SYSCFG_PMU_1>;
st,fiq-device = <ST_IRQ_SYSCFG_DISABLED>,
<ST_IRQ_SYSCFG_DISABLED>;
st,invert-ext = <(ST_IRQ_SYSCFG_EXT_1_INV | ST_IRQ_SYSCFG_EXT_3_INV)>;
};
