2024-08-30usb: ehci-mx5: Add a default for CFG_MXC_USB_PORTSCFabio Estevam
Just like drivers/usb/host/ehci-mx6.c, add a default for drivers/usb/host/ehci-mx5.c. The motivation for doing this is to remove CFG_MXC_USB_PORTSC from board config files. All the mx5 boards, with the exeption of mx51evk, define CFG_MXC_USB_PORTSC as: #define CFG_MXC_USB_PORTSC (PORT_PTS_UTMI | PORT_PTS_PTW) So move this definition as a default into ehci-mx5.c.

2024-04-05usb: xhci: Set up endpoints for the first 2 interfacesJanne Grunau
The xhci driver currently only does the necessary initialization for endpoints found in the first interface descriptor. Apple USB keyboards (released 2021) use the second interface descriptor for the HID keyboard boot protocol. To allow USB drivers to use endpoints from other interface descriptors the xhci driver needs to ensure these endpoints are initialized as well. Use USB_MAX_ACTIVE_INTERFACES to control how many interface descriptors are considered during endpoint initialisation. For now define it to 2 as that is sufficient for supporting the Apple keyboards.

2023-09-04usb: check for companion controller in uclassFabrice Gasnier
EHCI is usually used with companion controller (like OHCI) as companion controller. This information on the companion is missing currently in companion drivers. So, if the usb-uclass isn't aware, it may scan busses in any order: OHCI first, then EHCI. This is seen on STM32MP1 where DT probing makes the probe order to occur by increasing address (OHCI address < EHCI address). When a low speed or full-speed device is plugged in, it's not detected as EHCI should first detect it, and give ownership (handover) to OHCI.
