  clk: meson: mpll: fix mpll0 fractional part ignored
  clk: samsung: exynos5420: The EPLL rate table corrections
  clk: sunxi-ng: sun5i: Add clk_set_rate_parent to the CPU clock

Currently a bug in the sci_clk_get implementation causes it to always
return a clock belonging to the last device in the static list of clock
data. This is due to a bug in the init code that causes the array
used by sci_clk_get to only be populated with the clocks for the last
device, as each device overwrites the entire array with its own clocks.

Fix this by calculating the actual number of clocks for the SoC, and
allocating the whole array in one go. Also, we don't need the handle
to the init data array anymore after doing this, instead we can
just compare the dev_id / clk_id against the registered clocks and
use binary search for speed.

This patch fixes values of the EPLL K coefficient and changes
the EPLL output frequency values to match exactly what is
possible to achieve with given M, P, S, K coefficients.
This allows to avoid rounding errors and unexpected frequency
being set with clk_set_rate(), due to recalc_rate returning
different values than the PLL rate specified in the
exynos5420_epll_24mhz_tbl table. E.g. this prevents a case
where two consecutive clk_set_rate() calls with same argument
result in different PLL output frequency.

The PLL output frequencies have been calculated with formula:

f = fxtal * (M * 2^16 + K) / (P * 2^S) / 2^16

where fxtal = 24000000.

As there is no way to actually query the hardware for the current clock
rate, now racalc_rate() just returns the last rate that was previously
set. But if the rate was not set yet, we return the bogus rate of 1000Hz.

The branch clocks have the same rate as their parent, so in this case we
just need to remove recalc_rate ops and then the core framework will handle
this automagically. The round_rate() is unused, so remove it as well.

commit e2860e1f ("serial: 8250_of: Add reset support")
introduced reset support for the 8250_of driver.

However it unconditionally uses the assert/deassert pair to
deassert reset on the device at probe and assert it at
remove. This does not work with systems that have a
self-deasserting reset controller, such as Gemini, that
recently added a reset controller.

As a result, the console will not probe on the Gemini with
this message:

Serial: 8250/16550 driver, 1 ports, IRQ sharing disabled
of_serial: probe of 42000000.serial failed with error -524

This (-ENOTSUPP) is the error code returned by the
deassert() operation on self-deasserting reset controllers.

To work around this, implement dummy .assert() and
.deassert() operations in the Gemini combined clock and
reset controller. This fixes the issue on this system.

The output buffer input mux can be configured in either of three
states -- disabled, input from FOD, input from previous output.
Once the .prepare() callback of the output buffer is called, the
output buffer input mux must be set to either input from FOD or
input from previous output, it cannot be set to Disabled anymore
or the output won't work.

Default to the input from FOD if the output buffer input mux was
Disabled and the .prepare() was called on it.

Note that we do not set the output buffer input mux back to Disabled
in the .unprepare() callback as there is no obvious benefit of doing
so. We disable the entire output buffer in the .unprepare() callback
already.

In case the initial values of the FOD registers are not configured in
the OTP or by the bootloader, it is possible that the FOD registers
will contain zeroes. The code in vc5_fod_recalc_rate() immediately
feeds the FOD divider value obtained from the FOD registers into the
div64_u64() and if the FOD divider value is zero, triggers division
by zero exception.

Check if the FOD divider value is zero and return the frequency of
the FOD output as 0 Hz if it is so. This prevents the division by
zero exception.

AXS10X boards manages it's clocks using various PLLs. These PLL has same
dividers and corresponding control registers mapped to different addresses.
So we add one common driver for such PLLs.

Each PLL on AXS10X board consist of three dividers: IDIV, FBDIV and
ODIV. Output clock value is managed using these dividers.

We add pre-defined tables with supported rate values and appropriate
configurations of IDIV, FBDIV and ODIV for each value.

As of today we add support for PLLs that generate clock for the
following devices:
 * ARC core on AXC CPU tiles.
 * ARC PGU on ARC SDP Mainboard.
and more to come later.

By this patch we add support for two plls (arc core pll and pgu pll),
so we had to use two different init types: CLK_OF_DECLARE for arc core pll and
regular probing for pgu pll.
