[PATCH 0/5] clk: Use of_clk_get_parent_count() instead of open coding

[Geert Uytterhoeven <geert+renesas@xxxxxxxxx>]

	Hi all,

In several places, the functionality of of_clk_get_parent_count() is open
coded. Replace them by of_clk_get_parent_count() to reduce code size.

The first 3 patches can be applied independently, as the affected clock
drivers are used with CONFIG_COMMON_CLK=y and CONFIG_OF=y only.

Patch 4 adds dummy implementations of of_clk_get_parent_count() for the
cases where CONFIG_OF or CONFIG_COMMON_CLK are not set.
This is an RFC, as
  1. Dummies are needed in two places,
  2. We don't have any dummies yet for the !CCF case.

Patch 5 depends on patch 4, since the arm,sp804 timer is also used on
platforms where CONFIG_OF or CONFIG_COMMON_CLK are not set.

This was compile-tested using:
  - multi_v7_defconfig (CCF, OF)
  - realview_defconfig (CCF, no OF)
  - versatile_defconfig (no CCF, no OF)
  - bcm2835_defconfig (CCF, OF)
  - axm55xx_defconfig (CCF, OF)
  - at91_dt_defconfig (CCF, OF)
  - omap2plus_defconfig (CCF, OF)

Thanks!
