Clock "emc" is for the External Memory Controller. The USB driver has no
business touching this clock directly. Remove the code that does so.

Greg, Alan, I'd like to take this patch through the Tegra tree to avoid
any merge conflicts with the Tegra USB changes that have recently
happened there.
Venu, When creating your patch to convert the Tegra USB PHY driver to a
platform driver, can you assume these patches are applied first? Thanks.
I assume that these patches make sense to you; could you ack them if so.

The patch to add USB PHY nodes to device tree was written before Tegra
supported the clocks property in device tree. Now that it does, add the
required clocks properties to these nodes.
This will allow all clk_get_sys() calls in tegra_usb_phy.c to be replaced
by clk_get(phy->dev, clock_name), as part of converting the PHY driver to
a platform driver.

Hmmm. Thinking about that first clock more, if we name it just "phy" in
both the UTMI and ULPI PHY nodes, we could make tegra_phy_init() perform
the clk_get() for all PHY types, and use the same clock name everywhere,
and hence remove the type-specific clk_get()s from tegra_phy_init() and
utmip_pad_open().
Venu, will this work for other chips such as Tegra30/Tegra114 and so on
into the future, or do chips after Tegra20 introduce any new clocks, and
hence break this scheme?

Should be fine, as same clocks are used across all chips.

Thanks. I've applied both patches to Tegra's for-3.9/soc branch, with
patch 2/2 modified to name the first clock "phy" rather than "utmi" or
"ulpi".

Stephen,
This was primarily done to make sure that EMC is set to a minimum
frequency, below which data errors may occur during USB transfers.
If we plan to remove this, how should we make sure that the EMC
is programmed for the required frequency during USB transfers?

You could use something like the API I added in "ARM: tegra: add EMC
clock scaling API". This needs some rework and I looked into integrating
this with the DEVFREQ framework, but I don't think it fits too well.
Bandwidth requirements should always be communicated to the EMC driver
and not described by clock rates.
Regards,
Lucas

I agree.
Besides, on some boards there's an EMC scaling table defined already, so
the EMC driver is simply overriding the value the USB driver selects anyway.
