59fe66313a clk: versatile: remove unneeded error message
If kzalloc fails we will already have many messages in the log and we do
not need another message to know that kzalloc for sp810 has failed.

47c5ee34d8 clk: versatile: fix memory leak
If of_clk_parent_fill() fails then we printed an error message and
returned. But we missed freeing sp810.

62f4771198 clk: versatile: Switch to assigned clock parents
We're removing struct clk from the clk provider API. This code is
calling the consumer APIs to change the parent to a 1 MHz fixed
rate clock for each of the clocks that the driver provides. Move
to using the assigned-clock-parents DT property for this instead.
Because this is an ABI break, detect if the property is missing
and fall back to setting the parent explicitly before the clocks
are registered.

3294bee870 clk: versatile: off by one in clk_sp810_timerclken_of_get()
The ">" should be ">=" or we end up reading beyond the end of the array.

6d31e3b22e clk: versatile: Remove clk.h and clkdev.h includes
Clock provider drivers generally shouldn't include clk.h because
it's the consumer API. Remove the include here because this is a
provider driver. Also remove clkdev.h in files that aren't using
it and replace them with slab.h in files that were relying on the
implicit include of slab.h in clkdev.h.

6e973d2c43 clk: vexpress: Add separate SP810 driver
Factor out the SP810 clocking code into a separate driver,
selecting better (faster) parent at clk_prepare() time.
This is to avoid problems with clocking infrastructure
initialisation order, in particular to avoid dependency
of fixed clock being initialized before SP810. It also
makes vexpress platform OF-based clock initialisation code
unnecessary.
