Just curious: does the current Chip Idea USB driver work 'as is' on mx5?

Are you also going to submit the <soc>.dtsi and <board>.dts patches?

I would like to try it on a mx53qsb.

Regards,

Fabio Estevam

Not "as is" but we are working on it to get all patches for that
mainline. Currently there is the static CI13XXX_REQUIRE_TRANSCEIVER flag
in the ci13xxx_imx_data, which makes the socs with no real xceiver
depend on the nop-xceiver. But that one lags clk_prepare_{enable, disable}.
But we already prepared that in some, "hopefully ready for mainline", patches.

Yes, the dtsi patch is alread on the list:

we got it already running with that board and the above mentioned
dependencies.

Cheers,

This is very good news. I will wait for the patches to reach the
mainling lists and then will have a try.

Thanks,
