Subject: patch "usb: gadget: fsl: Re-enable driver for ARM SoCs" added to usb-linus
Date: Thu, 10 Jun 2021 20:02:23 +0200 [thread overview]
Message-ID: <162334814333203@kroah.com> (raw)
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.

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.

Some of Freescale PowerPC and i.MX processors have a High Speed
Dual-Role(DR) USB controller, which supports device mode.
