clk: rockchip: add pclk_cpu to the list of rk3188 critical clocks

pclk_cpu needs to keep running because it is needed for devices like
the act8865 regulator but with the recent gpio clock handling this is
not always the case anymore. So add it to the list of critical clocks.

clk: rockchip: handle critical clocks after registering all clocks

Currently the registration of critical clocks is done in the function
shared between rk3066 and rk3188 clock trees. That results in them
getting handled maybe before all of them are registered.

Therefore move the critical clock handling down to the end of the soc-
specific clock registration function, so that all clocks are registered
before they're maybe handled as critical clock.

clk: pistachio: Fix PLL rate calculation in integer mode

.recalc_rate callback for the fractional PLL doesn't take operating
mode into account when calculating PLL rate. This results in
the incorrect PLL rates when PLL is operating in integer mode.

Operating mode of fractional PLL is based on the value of the
fractional divider. Currently it assumes that the PLL will always
be configured in fractional mode which may not be
the case. This may result in the wrong output frequency.

Also vco was calculated based on the current operating mode which
makes no sense because .set_rate is setting operating mode. Instead,
vco should be calculated using PLL settings that are about to be set.

clk: pistachio: Fix override of clk-pll settings from boot loader

PLL enable callbacks are overriding PLL mode (int/frac) and
Noise reduction (on/off) settings set by the boot loader which
results in the incorrect clock rate.

PLL mode and noise reduction are defined by the DSMPD and DACPD bits

by deasserting all power-down bits of the PLL control register,

clk: rockchip: register pll mux before pll itself

The structure is xin24m -> pll -> pll-mux (xin24m,pll,xin32k). The pll
does have an init callback to make sure the boot-selected frequency is
using the expected pll settings and resets the same frequency using
the values provided in the driver if necessary.

The setting itself also involves remuxing the pll-mux temporarily to
the xin24m source to let the new pll rate settle. Until now this worked
flawlessly, even when it had the flaw of accessing the mux settings
before the mux actually got registered.

With the recent clock-core conversions this flaw became apparent in
null pointer dereference in
[<c03fc400>] (clk_hw_get_num_parents) from [<c0400df0>] (clk_mux_get_parent+0x14/0xc8)
[<c0400ddc>] (clk_mux_get_parent) from [<c040246c>] (rockchip_rk3066_pll_set_rate+0xd8/0x320)

So to fix that, simply register the pll-mux before the pll, so that
it will be fully initialized when the pll clock executes its init-
callback and possibly touches the pll-mux clock.

However TSADC is present only on Exynos4210 so on Trats2 board (with

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

clk: kill off set_irq_flags usage

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.

clk: rockchip: Fix PLL bandwidth

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).

MT8173 MMPLL frequency settings are different from common PLLs.
It needs different post divider settings for some ranges of frequency.
This patch add support for MT8173 MMPLL frequency setting by adding

clk: Allow providers to configure min/max rates

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.
