On SAMA7G5 the prescaler part of master clock has been implemented as a
changeable one. Everytime the prescaler is changed the PMC_SR.MCKRDY bit
must be polled. Value 1 for PMC_SR.MCKRDY means the prescaler update is
done. Driver polls for this bit until it becomes 1. On SAMA7G5 it has
been discovered that in some conditions the PMC_SR.MCKRDY is not rising
but the rate it provides it's stable. The workaround is to add a timeout
when polling for PMC_SR.MCKRDY. At the moment, for SAMA7G5, the prescaler
will be removed from Linux clock tree as all the frequencies for CPU could
be obtained from PLL and also there will be less overhead when changing
frequency via DVFS.

SAM9X60's PLL which is also part of SAMA7G5 is composed of 2 parts:
one fractional part and one divider. On SAMA7G5 the CPU PLL could be
changed at run-time to implement DVFS. The hardware clock tree on
SAMA7G5 for CPU PLL is as follows:
+---- div1 ----------------> cpuck
|
FRAC PLL ---> DIV PLL -+-> prescaler ---> div0 ---> mck0
The div1 block is not implemented in Linux; on prescaler block it has
been discovered a bug on some scenarios and will be removed from Linux
in next commits. Thus, the final clock tree that will be used in Linux
will be as follows:
+-----------> cpuck
|
FRAC PLL ---> DIV PLL -+-> div0 ---> mck0
It has been proposed in [1] to not introduce a new CPUFreq driver but
to overload the proper clock drivers with proper operation such that
cpufreq-dt to be used. To accomplish this DIV PLL and div0 implement
clock notifiers which applies safe dividers before FRAC PLL is changed.
The current commit treats only the DIV PLL by adding a notifier that
sets a safe divider on PRE_RATE_CHANGE events. The safe divider is
provided by initialization clock code (sama7g5.c). The div0 is treated
in next commits (to keep the changes as clean as possible).

clk: at91: re-factor clocks suspend/resume
SAMA5D2 and SAMA7G5 have a special power saving mode (backup mode) where
most of the SoC's components are powered off (including PMC). Resuming
from this mode is done with the help of bootloader. Peripherals are not
aware of the power saving mode thus most of them are disabling clocks in
proper suspend API and re-enable them in resume API without taking into
account the previously setup rate. Moreover some of the peripherals are
acting as wakeup sources and are not disabling the clocks in this
scenario, when suspending. Since backup mode cuts the power for
peripherals, in resume part these clocks needs to be re-configured.
The initial PMC suspend/resume code was designed only for SAMA5D2's PMC
(as it was the only one supporting backup mode). SAMA7G supports also
backup mode and its PMC is different (few new functionalities, different
registers offsets, different offsets in registers for each
functionalities). To address both SAMA5D2 and SAMA7G5 PMC add
.save_context()/.resume_context() support to each clocks driver and call
this from PMC driver.

As there is a `rate` field in clk_smd_rpm, clk_smd_rpm_recalc_rate() can
be used by branch clocks to report rate as well, rather than assuming
the rate is always same as parent clock. This assumption doesn't hold
on platforms like QCM2290, where xo_board is 38.4MHz while bi_tcxo is
19.2MHz.
To get this work, XO buffered clocks need the following updates.
- Assign a correct rate rather than the fake one which is being used to
generate binary value for clk_smd_rpm_req interface.
- Explicitly handle the clk_smd_rpm_req interface value for XO buffered
clocks (.rpm_res_type being QCOM_SMD_RPM_CLK_BUF_A).

0 means clock is not supplied and 1 means clock is supplied.
This patch fixes the issue by removing the inverted logic.
Fixing the above, triggered following 2 issues
1) GIC interrupts don't work if we disable IA55_CLK and DMAC_ACLK.
Fixed this issue by adding these clocks as critical clocks.
2) DMA is not working, since the DMA driver is not turning on DMAC_PCLK.
So will provide a fix in the DMA driver to turn on DMA_PCLK.

The CPU clocks don't currently have any owner (e.g., cpufreq-dt doesn't
enable() them -- and even if it did, it's not early enough compared to
other consumers -- nor does arch/arm64/kernel/smp.c), and instead are
simply assumed to be "on" all the time.
They are also parents of a few other clocks which haven't been
previously exposed for other devices to consume. If we want to expose
those clocks, then the common clock framework may eventually choose to
disable their parents (including the CPU PLLs) -- which is no fun for
anyone.
Thus, mark the CPU clocks as critical, to prevent them from being
disabled implicitly.

clk: mediatek: Fix corner case of tuner_en_reg
On MT8195, tuner_en_reg is moved to register offest 0x0.
If we only judge by tuner_en_reg, it may lead to wrong address.
Add tuner_en_bit to the check condition. And it has been confirmed,
on all the MediaTek SoCs, bit0 of offset 0x0 is always occupied by
clock square control.
