Not as far as I can see.  fixed-clock appears to have two properies:

        clock-frequency
        clock-output-names

and nothing else.  See of_fixed_clk_setup in drivers/clk/clk-fixed-rate.c.
You'll also find that the documentation in this file says this about it:

Looks like Documentation/devicetree/bindings/clock/fixed-clock.txt is
misleading then:

"Optional properties:
- gpios : From common gpio binding; gpio connection to clock enable pin."

It seems so.  It appears that the binding was added to clk-fixed-rate.c
here:

Date:   Sat Apr 7 21:39:39 2012 -0500

and the binding documentation separately:

Date:   Mon Apr 9 14:50:06 2012 -0500

From what I can see, this "gpios" property has never been supported.
