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).

* Texas Instruments LMP91000 potentiostat
http://www.ti.com/lit/ds/symlink/lmp91000.pdf
Required properties:
- compatible: should be "ti,lmp91000"
- reg: the I2C address of the device
- io-channels: the phandle of the iio provider
- ti,external-tia-resistor: if the property ti,tia-gain-ohm is not defined this
needs to be set to signal that an external resistor value is being used.
Optional properties:
- ti,tia-gain-ohm: ohm value of the internal resistor for the transimpedance
amplifier. Must be 2750, 3500, 7000, 14000, 35000, 120000, or 350000 ohms.
- ti,rload-ohm: ohm value of the internal resistor load applied to the gas
sensor. Must be 10, 33, 50, or 100 (default) ohms.
Example:
lmp91000@48 {
compatible = "ti,lmp91000";
reg = <0x48>;
ti,tia-gain-ohm = <7500>;
ti,rload = <100>;
io-channels = <&adc>;
};
