[PATCH 0/4] Introduce DesignWare USB3 Driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

the following patches introduce the DesignWare
USB3 Driver.

This controller will be used on the OMAP5 series
of processors and this is the first contribution
to Linux Kernel from OMAP5 program.

The driver is rather stable, but we have few issues
on the FPGA platform that we're using. It's very
complex platform and very timing and temperature-sensitive.

Thanks for Synopsys for all the help debugging many
issues with the HAPS platform (a valuable effort).

We will keep on adding new features to this driver
as the development goes, but as of now, it should behave
OK with Mass Storage and g_zero at least on FS/HS and SS.

Keep in mind that this was only tested on FPGA (HAPS-61)
and a virtual model of the HW and we might have to fix
a few things up when we get a real ASIC to test against.

Greg,

I will send you a pull request for this, if you prefer,
on monday, but I would suggest giving this a few days
or soaking in the mailing list so that other companies
which might be using this same IP have time to give it
a shot. Maybe Synopsys might also be willing to help
testing on HAPS-51 platform, but I'm speculating here ;-)

The original shortlog of the driver is quoted below
for reference:
