Some gate clocks have special needs which must be handled during the disable-unused clocks sequence. These needs might be driven by software due to the fact that we're disabling a clock outside of the normal clk_disable path and a clk's enable_count will not be accurate. On the other hand a specific hardware programming sequence might need to be followed for this corner case. This change is needed for the upcoming OMAP port to the common clock framework. Specifically, it is undesirable to treat the disable-unused path identically to the normal clk_disable path since other software layers are involved. In this case OMAP's clockdomain code throws WARNs and bails early due to the clock's enable_count being set to zero. A custom callback mitigates this problem nicely.

This fixes a bit error in the U8500 clock implementation: the unused p2_pclk12 registered at bit 12 in periphereral group 6 was defined as using bit 11 rather than bit 12. When walking over and disabling the unused clocks in the tree at late init time, p2_pclk12 was disabled, by effectively clearing the but for p2_pclk11 instead of bit 12 as it should have, thus disabling gpio block 6 and 7.

When a clock, C is initialised any orphan clocks listing C as a possible parent are reparented to it regardless of the parent requested by the orphan's get_parent() operation. This means that multiplexers registered before their parents are reparented to the first parent subsequently declared, regardless of the selection made by the hardware registers. For example: static const char *sel[] = { "srcA", "srcB", "dummy", "srcC" }; child = clk_register_mux(NULL, "child", sel, ARRAY_SIZE(sel), ...); clk_register_fixed(NULL, "dummy", ...); clk_register_fixed(NULL, "srcA", ...); clk_register_fixed(NULL, "srcB", ...); clk_register_fixed(NULL, "srcC", ...); Causes child's parent to always be "dummy". To fix this, when an orphanned clock has a get_parent() operation, only reparent to the clock indicated by get_parent().

Dummy clocks were added for ARM platforms, so that clk_get() for interface clk doesn't fail for amba devices from amba_probe(). Because there is no amba device for SPEAr that doesn't have a valid clock with dev_id for SPEAr, we don't need these dummy clocks. Hence, remove them.

It turns out that all platforms using the ICST VCO are really just touching two registers, and in the same way as well: one register with the VCO configuration as such, and one lock register that makes it possible to write to the VCO.
