...
* clk-basic-be:
clk: core: replace clk_{readl,writel} with {readl,writel}
clk: core: remove powerpc special handling
powerpc/512x: mark clocks as big endian
clk: mux: add explicit big endian support
clk: multiplier: add explicit big endian support
clk: gate: add explicit big endian support
clk: fractional-divider: add explicit big endian support
clk: divider: add explicit big endian support
This code is hand-rolling the CLK_IS_CRITICAL flag to keep a clk on once
it's registered. Just mark it as CLK_IS_CRITICAL instead so that the
framework can handle keeping the clk prepared and enabled for all
eternity.

The of_find_compatible_node() returns a node pointer with refcount
incremented, but there is the lack of use of the of_node_put() when
done. Add the missing of_node_put() to release the refcount.

Now that we have clk_hw based provider APIs to register clks, we
can get rid of struct clk pointers in this driver, allowing us to
move closer to a clear split of consumer and provider clk APIs.

This clock provider uses the consumer API, so include clk.h
explicitly.

With arch/arm calling of_clk_init(NULL) from time_init(), we can now
remove custom .init_time hooks. Highbank clock provider need a reference
to system registers, as a workaround current clk driver maps those
independent of arch code now.

The highbank clock will glitch with the current code if the
clock rate is reset without relocking the PLL. Program the PLL
correctly to prevent glitches.
