[2/3,v2] clk: versatile: Export icst_clk_setup()

Commit Message

Linus Walleij Feb. 19, 2020, 10:05 a.m. UTC

Export this clock setup method so we can register the
IM-PD1 clocks with common code in the next step.

Signed-off-by: Linus Walleij <[e-mail]>

ChangeLog v1->v2:
- New patch to reuse the machinery for properly probing
  device tree clocks using clk_hw etc.
