clk: core: Force setting the phase delay when no change
This patch reverts commit
023bd7166be0 ("clk: skip unnecessary
set_phase if nothing to do"), fixing two problems:
* in some SoCs, the hardware phase delay depends on the rate ratio of
the clock and its parent. So, changing this ratio may imply to set
new hardware values, even if the logical delay is the same.
* when the delay was the same as previously, an error was returned.

clk: Simplify __of_clk_get_hw_from_provider()
__of_clk_get_hw_from_provider() is confusing because it will
return EPROBE_DEFER if there isn't a ->get() or ->get_hw()
function pointer in a provider. That's just a bug though, and we
used to NULL pointer exception when ->get() was missing anyway,
so let's make this more obvious that they're not optional. The
assumption is that most providers will implement ->get_hw() so we
only fallback to the ->get() function if necessary. This
clarifies the intent and removes any possibility of probe defer
happening if clk providers are buggy.

clk: versatile/icst: add Integrator core module clocks
The Integrator/AP and Integrator/CP have special derivatives
of the ICST525 control registers, where some bits have been
hardwired but others are possible to adjust, resulting in a
control register that makes it possible to set an even,
desired megahertz value.
The Integrator/AP and Integrator/CP have slightly different
layout so we support them using different compatible
strings.
After adding these clocks, the Integrator-specific cpufreq
driver can be switched over to use the generic operating
point device tree cpufreq driver.
Instead of simply writing a value to the oscillator control
register we switch to the more elaborate method of providing
a bitmask and use regmap_update_bits() to poke the right bits
for the desired frequency, this is needed since these control
registers sometimes control more than one clock.

clk: tegra: remove TEGRA_PLL_USE_LOCK for PLLD/PLLD2
Tegra114 has a HW bug that the PLLD/PLLD2 lock bit cannot be asserted when
the DIS power domain is during up-powergating process but the clamp to this
domain is not removed yet. That causes a timeout and aborts the power
sequence, although the PLLD/PLLD2 has already locked. To remove the false
alarm, we don't use the lock for PLLD/PLLD2. Just wait 1ms and treat the
clocks as locked.

These clocks are the ones which will be used as source for the

Most of them are gatable. Most of the time their rate are their parent

choose between the TBG clocks for most of them.
However, some of them can't choose their parent or directly depend of the
xtal clocks. Other ones do not use exactly the same pattern to find the
ratio between their parent rate and their rate.
For these reason each clock is a composite clock and the operations they
use are different depending of the clock.
According to the datasheet it would be possible to select the parent
clock and the ratio, however currently the driver does not support it.

clk: twl6040: Rename the driver and use consistent names in the code
The driver is to provide the functional clock to OMAP4/5 McPDM. The clock
is named as pdmclk in the documentations so change the function names,
structure names and variables to align with this.
At the same time rename the driver from "twl6040-clk" to "twl6040-pdmclk".
This can be done w/o regression since the clock driver is not in use at
the moment, the MFD core driver is not even registering the device for it.

clk: twl6040: Register the clock as of_clk_provider
In order ot be able to use the pdmclk clock via DT it need to be registered
as of_clk_provide.
Since the twl6040 clock driver does not have it's own DT node, use the
parent's node for registering.

Both SATA and second USB3.0 interface are supported in Armada-39x SoC

The binding documentation has also been updated accordingly.
