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).

Device-Tree bindings for i2c gpio driver
Required properties:
- compatible = "i2c-gpio";
- gpios: sda and scl gpio
Optional properties:
- i2c-gpio,sda-open-drain: sda as open drain
- i2c-gpio,scl-open-drain: scl as open drain
- i2c-gpio,scl-output-only: scl as output only
- i2c-gpio,delay-us: delay between GPIO operations (may depend on each platform)
- i2c-gpio,timeout-ms: timeout to get data
Example nodes:
i2c@0 {
compatible = "i2c-gpio";
gpios = <&pioA 23 0 /* sda */
&pioA 24 0 /* scl */
>;
i2c-gpio,sda-open-drain;
i2c-gpio,scl-open-drain;
i2c-gpio,delay-us = <2>; /* ~100 kHz */
#address-cells = <1>;
#size-cells = <0>;
rv3029c2@56 {
compatible = "rv3029c2";
reg = <0x56>;
};
};
