usb: xhci: Fix double free on failure

2023-07-27T01:59:38Z

drivers/core/device.c will call `device_free()` after xhci_register already frees the private device data. This can cause a crash later during the boot process, observed on aarch64 RPi4b as a synchronous exception. All callers of xhci_register use priv_auto, so this won't lead to memory leaks.

usb: ehci-mx6: remove unnecessary regulator enable from probe

2023-07-21T00:05:10Z

Remove the regulator_set_enable() call from device probe which resolves a regulator imbalance. This is unnecessary as regulator_set_enable() will be called when ehci_register calls the init_after_reset hook. Suggested-by: Marek Vasut Signed-off-by: Tim Harvey

bootstd: Use bootdev instead of bootdevice

2023-07-16T15:13:17Z

It seems better to call this a 'bootdev' since this is name used in the documentation. The older 'Bootdevice' name is no-longer used and may cause confusion with the 'bootdevice' environment variable. Update throughout to use bootdev. Signed-off-by: Simon Glass Reviewed-by: Bin Meng

usb: dwc2: Fix the write to W1C fields in HPRT register

2023-06-21T11:15:58Z

Fix the write to the HPRT register which treat W1C fields as if they were mere RW. This leads to unintended clearing of such fields This bug was found during the testing on Simics model. Referring to specification DesignWare Cores USB 2.0 Hi-Speed On-The-Go (OTG) Databook (3.30a)"5.3.4.8 Host Port Control and Status Register (HPRT)", the HPRT.PrtPwr is cleared by this mistake. In the Linux driver (contrary to U-Boot), HPRT is always read using dwc2_read_hprt0 helper function which clears W1C bits. So after write back those bits are zeroes. Signed-off-by: Teik Heng Chong

usb: Move SPL_USB_HOST Kconfig symbol to drivers/usb/

2023-05-16T23:51:39Z

To avoid piling up all the various Kconfig symbols in one place, i.e. common/spl/Kconfig, move the USB Kconfig symbols into drivers/usb/ . This commit moves SPL_USB_HOST and updates help text of both USB_HOST and SPL_USB_HOST . Signed-off-by: Marek Vasut Reviewed-by: Tom Rini

bootstd: usb: Avoid initing USB twice

2023-05-13T13:52:32Z

This causes crashes on some boards, e.g. rockpro64. In any case, we should not do it. Check the usb_started flag to avoid this. Signed-off-by: Simon Glass Tested-by: Jonas Karlman Tested-by: Tom Rini

usb: Tidy up the usb_start flag

2023-05-13T13:52:32Z

This should be declared in a header file so that type-checking works correctly. Add a single declaration to usb.h and remove the others. Signed-off-by: Simon Glass Reviewed-by: Marek Vasut Reviewed-by: Patrick Delaunay

drivers: use dev_read_addr_ptr when cast to pointer

2023-05-06T09:28:18Z

The fdt_addr_t and phys_addr_t size have been decoupled. A 32bit CPU can expect 64-bit data from the device tree parser, so use dev_read_addr_ptr instead of the dev_read_addr function in the various files in the drivers directory that cast to a pointer. As we are there also streamline the error response to -EINVAL on return. Signed-off-by: Johan Jonker Reviewed-by: Simon Glass
