[ 5.048679] cros-ec-spi spi0.0: Command xfer error (err:-11)
[ 5.058672] cros-ec-i2c-tunnel ff110000.spi:ec@0:i2c-tunnel: Error transferring EC i2c message -11

Makes me think it can be disabled, or maybe something is kinda broken

Although, this in rk3288-veyron-chromebook.dtsi indicates otherwise?

&spi0 {
	status = "okay";
	spi-activate-delay = <100>;
	spi-max-frequency = <3000000>;
	spi-deactivate-delay = <200>;

	cros_ec: ec@0 {
		compatible = "google,cros-ec-spi";
		spi-max-frequency = <3000000>;
		interrupt-parent = <&gpio7>;
		interrupts = <7 IRQ_TYPE_LEVEL_LOW>;
		ec-interrupt = <&gpio7 7 GPIO_ACTIVE_LOW>;
		pinctrl-names = "default";
		pinctrl-0 = <&ec_int>;
		reg = <0>;
		google,cros-ec-spi-pre-delay = <30>;

		i2c_tunnel: i2c-tunnel {
			compatible = "google,cros-ec-i2c-tunnel";
			google,remote-bus = <0>;
			#address-cells = <1>;
			#size-cells = <0>;
		};
	};
};

It definitely is, the keyboard and mouse both rely on the cros ec tunnel to function.

Those errors dont seem to affect functionality, and are pretty minor so look into this later.

Closing this, as the errors don't seem to effect functionality
