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).

* GPIO beeper device tree bindings
Register a beeper connected to GPIO pin.
Required properties:
- compatible: Should be "gpio-beeper".
- gpios: From common gpio binding; gpio connection to beeper enable pin.
Example:
beeper: beeper {
compatible = "gpio-beeper";
gpios = <&gpio3 23 GPIO_ACTIVE_HIGH>;
};
