From: Stephen Warren <swarren@nvidia.com>

This clock has been missing from all our upstream clock drivers. Add it
by copying the tegra_clk_periph_gate() call from Tegra30; the data
matches what's in the ChromeOS kernel for this clock.

Mike, I'd need to apply this to the Tegra tree as part of the common
clock framework conversion.

In the latest Tegra CCF series that I posted, I've rolled all these
small fixes in already.
