Subject: arm64: tegra: Let the EMC hardware use the EMC clock
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0bab86abe5b8c0c9491d44074d8abb012aa256e3;p=linux.git

arm64: tegra: Let the EMC hardware use the EMC clock

The EMC hardware block needs access to the EMC clock in order to scale
the external memory frequency. Add the clocks property so that drivers
for the EMC can acquire a reference to the EMC clock.
