Subject: clk: tegra: pll: Add tegra_pll_wait_for_lock to clk header
X-Git-Tag: v4.5-rc1~82^2~1^2~20
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6583a6309e83e89f00e104c4ffd9df01d2e5a9f8;p=karo-tx-linux.git

clk: tegra: pll: Add tegra_pll_wait_for_lock to clk header

Create a wrapper interface to make use of the existing
clk_pll_wait_for_lock. This will be useful for implementations
of callbacks in Tegra SoC specific clock drivers.
