The mux in the clkout path needs the current selected parent to
be enabled for the switch to work. Use the correct mux type
to have the clk framework take care of this requirement.

When configuring a kernel including support for Renesas ARM/ARM64 Socs,
but excluding support for the RZ/N1D SoC, the user is always asked about
the RZ/N1D clock driver. As this driver is already auto-selected when
building a kernel including support for the RZ/N1D SoC, there is no need
to make the CLK_R9A06G032 symbol visible, unless compile-testing.
Align the symbol description with the other symbols.

It appears that some code lines raise the question why they are needed
and how they are participated in the calculus of the resulting values.

MSM8939 has 3 a53pll clocks with different frequency table for Cluster0,
Cluster1 and CCI. It adds function qcom_a53pll_get_freq_tbl() to create
pll_freq_tbl from OPP, so that those a53pll frequencies can be defined
in DT with operating-points-v2 bindings rather than being coded in the
driver. In this case, one compatible rather than three would be needed
for these 3 a53pll clocks.

Different from MSM8916 which has only one a53pll/mux clock, MSM8939 gets
three for Cluster0 (little cores), Cluster1 (big cores) and CCI (Cache
Coherent Interconnect). That said, a53pll/mux clock needs to be named
uniquely. Append @unit-address of device node to the clock name, so
that a53pll/mux will be named like below on MSM8939.
a53pll@b016000
a53pll@b116000
a53pll@b1d0000
a53mux@b1d1000

The clock source for MSM8916 cpu cores is like below.
|\
a53pll --------| \ a53mux +------+
| |------------| cpus |
gpll0_vote --------| / +------+
|/
So a53mux rather than a53pll is actually the parent clock of cpu cores.
It makes more sense to flag a53mux as critical instead, so that when
either a53pll or gpll0_vote is used by cpu cores, the clock will be kept
enabled while the other can be disabled.

As GDSCs are registered and found to be already enabled gdsc_init()
ensures that 1) the kernel state matches the hardware state, and 2)
votable GDSCs are properly enabled from this master as well.
But as the (optional) supply regulator is enabled deep into
gdsc_toggle_logic(), which is only executed for votable GDSCs, the
kernel's state of the regulator might not match the hardware. The
regulator might be automatically turned off if no other users are
present or the next call to gdsc_disable() would cause an unbalanced
regulator_disable().
Given that the votable case deals with an already enabled GDSC, most of
gdsc_enable() and gdsc_toggle_logic() can be skipped. Reduce it to just
clearing the SW_COLLAPSE_MASK and enabling hardware control to simply
call regulator_enable() in both cases.
The enablement of hardware control seems to be an independent property
from the GDSC being enabled, so this is moved outside that conditional
segment.
Lastly, as the propagation of ALWAYS_ON to GENPD_FLAG_ALWAYS_ON needs to
happen regardless of the initial state this is grouped together with the
other sc->pd updates at the end of the function.

.determine_rate is meant to replace .round_rate. The former comes with a
benefit which is especially relevant on 32-bit systems: since
.determine_rate uses an "unsigned long" (compared to a "signed long"
which is used by .round_rate) the maximum value on 32-bit systems
increases from 2^31 (or approx. 2.14GHz) to 2^32 (or approx. 4.29GHz).
Implement .determine_rate in addition to .round_rate so drivers that are
using clk_divider_{ro_,}ops can benefit from this by default. Keep the
.round_rate callback for now since some drivers rely on
clk_divider_ops.round_rate being implemented.

Currently, no driver support for DDR memory controller (DMC) is present,
as a result, no driver is explicitly consuming the ddrphy clock. This means
that VPLL1 (parent of ddr clock) will be shutdown if we enable
and then disable any child clock of VPLL1 (e.g. SCLK_I2S0_8CH_TX).
If VPLL1 is disabled, the whole system will freeze, because the DDR
controller will lose its clock. So, it's necessary to prevent VPLL1 from
shutting down, by marking the ddrphy4x CLK_IS_CRITICAL.
This bug was discovered when I was porting rockchip_i2s_tdm driver to
mainline kernel from Rockchip 4.4 kernel. I guess that other Rockchip
SoCs without DMC driver may need the same patch. If this applies to
other devices, please let us know.

The rk3036/rk3328 pll types were converted to checking the lock status
via the internal register in january 2020, so don't need the grf
reference since then.
But it was forgotten to remove grf check when deciding between the
pll rate ops (read-only vs. read-write), so a clock driver without
the needed grf reference might've been put into the read-only mode
just because the grf reference was missing.
This affected the rk356x that needs to reclock certain plls at boot.
Fix this by removing the check for the grf for selecting the utilized
operations.

so it is possible to config:

Although it does not cause build breaks with such configuration,
I think it is clearer to make COMMON_CLK_MT8167* depend on
