The jz4740-cgu driver already has access to the CGU, so it makes sense
to move the few remaining accesses to the CGU from arch/mips/jz4740
there too. Move the jz4740_clock_{suspend,resume} functions there for
such consistency. The arch/mips/jz4740/clock.c file now contains nothing
more of use & so is removed.

This driver supports the CGU clocks for Ingenic SoCs. It is generic
enough to be usable across at least the JZ4740 to the JZ4780, and will
be made use of on such devices in subsequent commits. This patch by
itself only adds the SoC-agnostic infrastructure that forms the bulk of
the CGU driver for the aforementioned further commits to make use of.

When registering clk-si5351 by platform_data, we should not pass struct clk
for the reference clocks. Drop struct clk from platform_data and rework the
driver to use devm_clk_get of named clock references.
While at it, check for at least one valid input clock and properly prepare/
enable valid reference clocks.

Before commit 035a61c314 ("clk: Make clk API return per-user
struct clk instances") we acquired the enable_lock in
__clk_set_parent_{before,after}() by means of calling
clk_enable(). After commit 035a61c314 we use clk_core_enable()
in place of the clk_enable(), and clk_core_enable() doesn't
acquire the enable_lock. This opens up a race condition between
clk_set_parent() and clk_enable(). Fix it.

Commit ae43b32891 ("ARM: 8202/1: dmaengine: pl330: Add runtime Power
Management support v12") added pm support for the pl330 dma driver but
it makes the clock for the Exynos5420 MDMA0 DMA controller to be gated
during suspend and this in turn makes its parent clock aclk266_g2d to
be gated. But the clock needs to be ungated prior suspend to allow the
system to be suspend and resumed correctly.
Add GATE_BUS_TOP register to the list of registers to be restored when
the system enters into a suspend state so aclk266_g2d will be ungated.
Thanks to Abhilash Kesavan for figuring out that this was the issue.

clk_calc_new_rates is assuming these functions can't return a negative

Some board designers, when running out of clock output pads, decide to
(mis)use PWM output pads to provide a clock to external components.
This driver supports this practice by providing an adapter between the
PWM and clock bindings in the device tree. As the PWM bindings specify
the period in the device tree, this is a fixed clock.

The pxa3xx scheduler relies on the pxa-timer, which requires a clock for
its rate. As the clock handling will be taken over by the clock
framework, add this missing clock.
The miss was discovered by attempting to run a zylonite platform in a
device-tree configuration, with the future patch to shift clocks
handling to clock framework applied.

The current parent, plld_out0, does not exist. The proper name is
pll_d_out0. While at it, rename the plld_dsi clock to pll_d_dsi_out to
be more consistent with other clock names.

There is no reason why Tegra114 cannot use the same generic code to set
up the oscillator, clk_m and pll_ref clocks. The only effective change
that this causes is that the CLK_SET_PARENT_RATE flag is dropped, but
since these clocks are all fixed it is not needed anyway.

Currently the Tegra clock driver simplifies the clock tree somewhat by
taking advantage of the fact that clk_m runs at the same frequency as
the oscillator. While that's true on all currently supported SoCs, it
does not apply to Tegra210 anymore. On Tegra210 clk_m is typically
divided down from the oscillator frequency. To support that setup, add
a separate clock for the oscillator that both clk_m and pll_ref derive
from.
Modify the tegra_osc_clk_init() function to take an additional divider
parameter for clk_m. Existing SoCs always pass in 1, whereas Tegra210
will read the divider from a register in the clock & reset controller.

Tegra210 has an extra bank of peripheral clock registers. Add it to the
generic peripheral clock code.

The number of resets controls is 32 times the number of peripheral
register banks rather than 32 times the number of clocks. This reduces
(drastically) the number of reset controls registered from 10080 (315
clocks * 32) to 224 (6 peripheral register banks * 32).
This also fixes a potential crash because trying to use any of the
excess reset controls (224-10079) would have caused accesses beyond
the array bounds of the peripheral register banks definition array.
