All users are DT-only and it makes no sense to keep
unused code

Are you sure about this? I still see a bunch of board files in mach-omap2 using
twl4030.

Thanks

You are right, on v4.9 it is still used in arch/arm/mach-omap2/twl-common.c.
I forgot to mention that I'm targeting v4.10 with this. On Tony's
for-next [0], there are no users:
git grep twl4030_usb_data
drivers/phy/phy-twl4030-usb.c:  struct twl4030_usb_data *pdata =
dev_get_platdata(&pdev->dev);
drivers/usb/phy/phy-twl6030-usb.c:      struct twl4030_usb_data *pdata
= dev_get_platdata(dev);
include/linux/i2c/twl.h:struct twl4030_usb_data {
include/linux/i2c/twl.h:        struct twl4030_usb_data                 *usb;

Thanks,
Nicolae

Yeah might be worht waiting on the omap3 specific driver changes until
v4.11 merge window unless the changes are blocking twl core clean up work.

Tony
