Hi,

I'm using the DM37x EVM and need to trigger the vibra ports on the

TPS65950.

It appears that I just need to define INPUT_TWL4030_VIBRA in the

config.

After doing this, I see that the twl4030-vibra platform driver is

registered, but the

twl4030_vibra_probe() function is never called.
Is there something I need to do to the board or to board-omap3evm.c so

that the

device is available and probing can happen?

Thanks,
Paul

Actually, after a bit of debugging, I've found the cause and solution.

The vibra device registration is skipped in twl4030_codec_probe()
because the vibra field of omap3evm_codec_data is missing from
board-omap3evm.c.

Adding the initialisation of this field to something appropriate fixes
the problem.
