This code is never called with a basic clock type, so the check
here is not doing anything useful and is blocking the removal of
__clk_get_flags(). Remove the check so we can delete the
__clk_get_flags() API.

clk providers shouldn't need to use the consumer APIs (clk.h).
Add provider APIs to replace the __clk_*() APIs that take a
struct clk_hw as their first argument instead of a struct clk.

Neither spdif_src nor spdif_pll exists, judging by the vendor kernel in
both cases spdif_pre was meant. This brings the naming in line and
hierachy in line with that of sclk_i2s0.
Also allow sclk_spdif and spdif_frac to change their parents rate as
that the upstream dividers are purely there to feed sclk_spdif

While children of orphan clocks are not carried in the orphan-list itself,
they're nevertheless orphans in their own right as they also don't have an
input-rate available. To ease tracking if a clock is an orphan or has an
orphan in its parent path introduce an orphan field into struct clk and
update it and the fields in child-clocks when a clock gets added or removed
from the orphan-list.

The gates were handled with a common piece of framework that was
registering all gates array, that was not using the CLK_OF_DECLARE logic,
and was not using clock-indices but some private masks that were pretty
much equivalent.
Move this code in a new driver that handles all the gates array and solves
both these issues.

The TSADC gate clock was used in Exynos4x12 DTSI for exynos-adc driver.
However TSADC is present only on Exynos4210 so on Trats2 board (with
Exynos4412 SoC) the exynos-adc driver could not be probed:
ERROR: could not get clock /adc@126C0000:adc(0)
exynos-adc 126c0000.adc: failed getting clock, err = -2
exynos-adc: probe of 126c0000.adc failed with error -2
Instead on Exynos4x12 SoCs the main clock used by Analog to Digital
Converter is located in different register and it is named in datasheet
as PCLK_ADC. Regardless of the name the purpose of this PCLK_ADC clock
is the same as purpose of TSADC from Exynos4210.
The patch adds gate clock for Exynos4x12 using the proper register so
backward compatibility is preserved. This fixes the probe of exynos-adc
driver on Exynos4x12 boards and allows accessing sensors connected to it
on Trats2 board (ntc,ncp15wb473 AP and battery thermistors).

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:
IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN
For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.

In the TRM we see that BWADJ is "a 12-bit bus that selects the values
1-4096 for the bandwidth divider (NB)":
NB = BWADJ[11:0] + 1
The recommended setting of NB: NB = NF / 2.
So:
NB = NF / 2
BWADJ[11:0] + 1 = NF / 2
BWADJ[11:0] = NF / 2 - 1
Right now, we have:
{ \
.rate = _rate##U, \
.nr = _nr, \
.nf = _nf, \
.no = _no, \
.bwadj = (_nf >> 1), \
}
That means we set bwadj to NF / 2, not NF / 2 - 1
All of this is a bit confusing because we specify "NR" (the 1-based
value), "NF" (the 1-based value), "NO" (the 1-based value), but
"BWADJ" (the 0-based value) instead of "NB" (the 1-based value).
Let's change to working with "NB" and fix the off by one error. This
may affect PLL jitter in a small way (hopefully for the better).

clk providers are using the consumer APIs to set min/max rates on
the clock they're providing. To encourage clk providers to move
away from the consumer APIs, add a provider API to set the
min/max rate of a clock. The assumption is that this is done
before the clock can be requested via clk_get() and that the
clock rate is already within the boundaries of the min/max that's
configured.
