board: librem5: tps65982: Clear the dead battery flag · 49f43e18

Sebastian Krzyszkowiak authored 2 years ago

When TPS65982 boots in a dead battery condition, it expects the host to
send a command to clear the dead battery flag once the system is able to
provide power from the battery. In dead battery mode, TPS65982 turns off
several features like power role switching and operates solely on external
power to ensure that the system can stay operational on USB power only.

On the Librem 5, the userspace is configured to trigger BQ25895's shipping
mode after powering the system off. This means that every time a user
connects a charger while the phone is off, TPS65982 detects a dead battery
condition. This results in TPS65982 rebooting itself into regular mode once
the charger is unplugged. To prevent that, check whether battery voltage is
present and gracefully clear the dead battery flag if that's the case.

usb: dwc3: dwc3-generic: check the parent nodes · ba93541c

Angus Ainslie authored 3 years ago


The kernel devicetree has definitions for port and hub nodes as subnodes
to the USB devices. These subnodes don't contain all of the data required
to properly configure the dwc3. Check the parent nodes if the data is not
in the port/hub node.

Here's an example from the librem5 kernel dts file

&usb_dwc3_0 {
	#address-cells = <1>;
	#size-cells = <0>;
	dr_mode = "otg";
	snps,dis_u3_susphy_quirk;
	status = "okay";

	port@0 {
		reg = <0>;

		typec_hs: endpoint {
			remote-endpoint = <&usb_con_hs>;
		};
	};

	port@1 {
		reg = <1>;

		typec_ss: endpoint {
			remote-endpoint = <&usb_con_ss>;
		};
	};
};

&usb_dwc3_1 {
	dr_mode = "host";
	status = "okay";
	#address-cells = <1>;
	#size-cells = <0>;

	/* Microchip USB2642 */
	hub@1 {
		compatible = "usb424,2640";
		reg = <1>;
		#address-cells = <1>;
		#size-cells = <0>;

		mass-storage@1 {
			compatible = "usb424,4041";
			reg = <1>;
		};
	};
};

When CONFIG_DM_USB is not defined then usb_gadget_initialize is just a call
