Subject[PATCH V3 00/12] clk: Add non CONFIG_HAVE_CLK routines
Date
Many drivers are shared between architectures that may or may not have HAVE_CLK
selected for them. To remove compilation errors for them we enclose clk_*()
calls in these drivers within #ifdef CONFIG_HAVE_CLK, #endif.

This patchset removes the need of these CONFIG_HAVE_CLK statements, by
introducing dummy routines when HAVE_CLK is not selected by platforms. So,
definition of these routines will always be available. These calls will return
error for platforms that don't select HAVE_CLK.

I hope i don't break anything now. ;)

V2->V3:
- Dummy routines now return NULL or 0.
- All user drivers must fail if clk_get returned error other than NULL.
- All user drivers don't need to validate their clk pointer before every call to
clk_*() routines.
- Patches dropped earlier are again taken back, as they were following similar
approach to what is implemented now.

V1->V2:
- Removed few patches as they might break working drivers
- Updated 1st patch, as it doesn't apply cleanly on latest linux-next after this
got applied.

ARM: 7376/1: clkdev: Implement managed clk_get()

- Similarly, updated stmmac patch as there were updates for it too.
