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

2021-11-09T11:48:23Z

[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

usb: Enforce DM_USB migration for USB_HOST devices.

2021-07-19T01:05:31Z

As the deadline for migration to DM_USB, when using a USB host controller has now gone two years past the deadline, enforce migration. This is done by: - Ensuring that all host controller options (other than the very legacy old MUSB ones) now select USB_HOST. USB_HOST now enforces DM_USB and OF_CONTROL. - Remove other parts of Kconfig logic that had platforms pick DM_USB. - To keep Kconfig happy, have some select statements test for USB_HOST as well. - Re-order some Kconfig entries and menus so that we can cleanly pick host or gadget roles. For the various HCD options that have platform glue options, group them together and update dependencies in some cases. - As SPL_DM_USB is not required, on platforms that had not yet enabled it, disable it.

usb: dwc3-generic: Disable host driver definition if gadget only

Even if only USB gadget is defined, dwc3 generic driver enables a definition and probe/remove functions for host driver. This enables the definition if USB_HOST is enabled only. Signed-off-by: Kunihiko Hayashi

usb: dwc3-meson-g12a: skip phy on -ENODATA aswell

2021-05-14T15:41:12Z

If the PHY isn't specified in the DT, -ENODATA means it should be skipped, handle it like -ENOENT. With that, devices without USB3 supported can have USB working (Odroid-HC4). Fixes: adb049abf7 ("usb: dwc3: Add Meson G12A USB Glue") Signed-off-by: Neil Armstrong
