Subject: [PATCH] ARM: multi_v7_defconfig: Make NOP_USB_XCEIV driver built-in
Date: Sat, 10 Jul 2021 13:04:55 +0200	[thread overview]
Message-ID: <1625915095-23077-1-git-send-email-stefan.wahren@i2se.com> (raw)

The usage of usb-nop-xceiv PHY on Raspberry Pi boards with BCM283x has
been a "regression source" a lot of times. The last case is breakage of
USB mass storage boot has been commit e590474768f1 ("driver core: Set
fw_devlink=on by default") for multi_v7_defconfig. As long as
NOP_USB_XCEIV is configured as module, the dwc2 USB driver defer probing
endlessly and prevent booting from USB mass storage device. So make
the driver built-in as in bcm2835_defconfig and arm64/defconfig.
