This is a note to let you know that I've just added the patch titled
usb: gadget: fsl: Re-enable driver for ARM SoCs
to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-linus branch.
The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.
If you have any questions about this process, please let me know.

From: Joel Stanley joel@jms.id.au Date: Thu, 10 Jun 2021 13:19:57 +0930 Subject: usb: gadget: fsl: Re-enable driver for ARM SoCs
The commit a390bef7db1f ("usb: gadget: fsl_mxc_udc: Remove the driver") dropped the ARCH_MXC dependency from USB_FSL_USB2, leaving it depending solely on FSL_SOC.
FSL_SOC is powerpc only; it was briefly available on ARM in 2014 but was removed by commit cfd074ad8600 ("ARM: imx: temporarily remove CONFIG_SOC_FSL from LS1021A"). Therefore the driver can no longer be enabled on ARM platforms.
This appears to be a mistake as arm64's ARCH_LAYERSCAPE and arm32 SOC_LS1021A SoCs use this symbol. It's enabled in these defconfigs:
arch/arm/configs/imx_v6_v7_defconfig:CONFIG_USB_FSL_USB2=y arch/arm/configs/multi_v7_defconfig:CONFIG_USB_FSL_USB2=y arch/powerpc/configs/mgcoge_defconfig:CONFIG_USB_FSL_USB2=y arch/powerpc/configs/mpc512x_defconfig:CONFIG_USB_FSL_USB2=y
To fix, expand the dependencies so USB_FSL_USB2 can be enabled on the ARM platforms, and with COMPILE_TEST.
