[PATCH 0/3] ARM: da8xx: remove con_id from USB clocks

[David Lechner]

This series removes unnecessary con_ids on da8xx USB clocks in preparation
of adding device tree support for clocks on this platform.

Note: this is a resend  of "USB: musb: da8xx: remove clock con_id" and
"USB: ohci: da8xx: remove clk con_id". I sent them before I realized that
things break if you don't also remove the con_id when registering the
clkdev. :-/

[PATCH 1/3] USB: musb: da8xx: remove clock con_id

[David Lechner]

There is only one clock for the DA8xx MUSB device, so we don't need the
con_id, so remove it. This way we don't have to add an unnecessary
property to the device tree bindings for the clock.

[PATCH 2/3] USB: ohci: da8xx: remove clk con_id

[David Lechner]

The ohci-da8xx device only has one clock, so a con_id is not needed, so
remove it. This way we don't have to add an unnecessary property to the
device tree bindings for the clock.

[PATCH 3/3] ARM: da8xx: remove con_id from USB clocks

[David Lechner]

There is only one clock each for "musb-da8xx" and "ohci-da8xx", so we
do not the the con_id. Removing them  will also prevent needing an
unnecessary device tree property when device tree bindings are added
for clocks.
