Subject: [PATCH v3 2/5] ARM: timer-sp: Use of_clk_get_parent_count() instead of open coding

Signed-off-by: Geert Uytterhoeven <geert+renesas@...der.be>
Acked-by: Daniel Lezcano <daniel.lezcano@...aro.org>
---
This depends on "[PATCH v3 1/5] clk: Extract OF clock helpers in
<linux/of_clk.h>".

v3:
  - Add Acked-by,

v2:
  - of_clk_get_parent_count() was moved to <linux/of_clk.h>,
  - Dropped RFC, as a dummy is now available in the !CONFIG_COMMON_CLK
    case.
