usb: dwc3: Fix non-usb3 configurations

2022-05-20T21:30:36Z

Missing nodes may also be signaled via -ENODATA. We need to check for that to prevent failing in non-usb3 setups. Furthermore, dev.phy must be NULL'ed in case usb3-phy was not found. Fixes: 142d50fbce7c ("usb: dwc3: Add support for usb3-phy PHY configuration") Signed-off-by: Jan Kiszka

usb: dwc3: Add support for usb3-phy PHY configuration

2022-04-22T08:35:14Z

When usb3-phy label is found, PHY driver is called and serdes line is initialized. This is preparation for serdes/psgtr driver to configure GT lines based on description in DT. Signed-off-by: Michal Simek

usb: dwc3: Implement .glue_configure for i.MX8MP

2022-04-21T10:44:23Z

The i.MX8MP glue needs to be configured based on a couple of DT properties, implement .glue_configure callback to parse those DT properties and configure the glue accordingly.

usb: dwc3: Rename .select_dr_mode to .glue_configure

2022-04-21T10:44:23Z

Rename the select_dr_mode callback to glue_configure, the callback is used for more than enforcing controller mode even on the TI chips, so change the name to a more generic one. No functional change.

usb: dwc3: core: stop the core when it's removed

If u-boot doesn't stop the core when it's finished with it then linux can't find it. Signed-off-by: Angus Ainslie

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

2022-02-16T15:52:56Z

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>; }; }; }; Signed-off-by: Angus Ainslie

usb: dwc3: add layerscape support

2021-11-09T11:48:23Z

Add support for the proper dwc3 device tree binding support as specified in the offical device tree spec. Initially, add support for the LS1028A support. Other SoCs should be easy to add by just adding the corresponding compatible string. Unfortunately, the device trees of all other layerscape SoCs are not converted and uses a wrong compatible string only known in u-boot. To maintain backwards compatibility with current u-boot device trees, add the generic "fsl,layerscape-dwc3" compatible string. OTG mode is not supported yet. The dr_mode in the devicetree will either have to be set to peripheral or host. Signed-off-by: Michael Walle Reviewed-by: Priyanka Jain

usb: dwc3: Enable undefined length INCR burst type

[backport from linux commit d9612c2f0449e24983a8b689603210486a930c90] Enable the undefined length INCR burst type and set INCRx. Different platform may has the different burst size type. In order to get best performance, we need to tune the burst size to one special value, instead of the default value. Signed-off-by: Michael Walle Reviewed-by: Priyanka Jain
