The exclusive gates may be set up in the wrong way by software running
before the clock driver comes up. In that case the exclusive setup is
locked in its initial state, as the complementary function can't be
activated without disabling the initial setup first.
To avoid this lock situation, reset the exclusive gates to the off
state and allow the kernel to provide the proper setup.

On H3 (ES1.x, ES2.0) and M3-W (ES1.0, ES1.1) the clock setting for HS400
needs a quirk to function properly. The reason for the quirk is that
there are two settings which produces same divider value for the SDn
clock. On the effected boards the one currently selected results in
HS400 not working.
This change uses the same method as the Gen2 CPG driver and simply
ignores the first clock setting as this is the offending one when
selecting the settings. Which of the two possible settings is used have
no effect for SDR104.

The driver tries to figure out which state a SD clock is in when the
clock is registered, instead of setting a known state. This can be
problematic for two reasons.
1. If the clock driver can't figure out the state of the clock,
registration of the clock fails, and setting of a known state by a
clock user is not possible.
2. The state of the clock depends on if and how the bootloader
configured it. The driver only checks that the rate is known, not if
the clock is stopped or not for example.
Fix this by setting a known state and making sure the clock is stopped.

do not have own DT node. The clock provider information is usually in the
main device node which is owned by the MFD device. Change the devm variant

device has no own node or if the node does not contain the #clock-cells
property. In such case use the parent node if it contains the #clock-cells.

All the audio interfaces on Allwinner SoCs need to change their module
clocks during operation, to switch between support for 44.1 kHz and 48
kHz family sample rates. The clock rate for the module clocks is
governed by their upstream audio PLL. The module clocks themselves only
have a gate, and sometimes a divider or mux. Thus any rate changes need
to be propagated upstream.
Set the CLK_SET_RATE_PARENT flag for all audio module clocks to achieve
this.

The audio blocks require specific clock rates. Until now we were using
the closest clock rate possible with integer N-M factors. This resulted
in audio playback being slightly slower than it should be.
The vendor kernel gets around this (for newer SoCs) by using sigma-delta
modulation to generate a fractional-N factor. As the PLL hardware is
identical in most chips, we can back port the settings from the newer
SoC, in this case the H3, onto the A33.

i.MX7ULP Clock functions are under joint control of the System
Clock Generation (SCG) modules, Peripheral Clock Control (PCC)
modules, and Core Mode Controller (CMC)1 blocks
The clocking scheme provides clear separation between M4 domain
and A7 domain. Except for a few clock sources shared between two
domains, such as the System Oscillator clock, the Slow IRC (SIRC),
and and the Fast IRC clock (FIRCLK), clock sources and clock
management are separated and contained within each domain.
M4 clock management consists of SCG0, PCC0, PCC1, and CMC0 modules.
A7 clock management consists of SCG1, PCC2, PCC3, and CMC1 modules.
This driver only adds clock support in A7 domain.
Note that most clocks required to be operated when gated, e.g. pll,
pfd, pcc. And more special cases that scs/ddr/nic mux selecting
different clock source requires that clock to be enabled first,
then we need set CLK_OPS_PARENT_ENABLE flag for them properly.
