Subject: phy: ti-pipe3: Introduce mode property in driver data
X-Git-Tag: v2020.01~10^2~3
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=53df65a9d2bafcd6ef01f27888fb7be61e7bbd08;p=oweals%2Fu-boot.git

phy: ti-pipe3: Introduce mode property in driver data

Introduce a mode property in the driver data so that
we don't have to keep using "of_device_is_compatible()"
throughtout the driver.

No functional change.
