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).

Allwinner sun4i and sun7i SoC PWM controller
Required properties:
- compatible: should be one of:
- "allwinner,sun4i-a10-pwm"
- "allwinner,sun5i-a10s-pwm"
- "allwinner,sun5i-a13-pwm"
- "allwinner,sun7i-a20-pwm"
- "allwinner,sun8i-h3-pwm"
- reg: physical base address and length of the controller's registers
- #pwm-cells: should be 3. See pwm.txt in this directory for a description of
the cells format.
- clocks: From common clock binding, handle to the parent clock.
Example:
pwm: pwm@01c20e00 {
compatible = "allwinner,sun7i-a20-pwm";
reg = <0x01c20e00 0xc>;
clocks = <&osc24M>;
#pwm-cells = <3>;
};
