If we exit the for_each_of_cpu_node loop early, the reference on the
current node must be decremented, otherwise there is a leak.

This is because the "powersave" mux clock 0 was provided in an unterminated
array, which is required by the loop in the driver:
/* Count, allocate, and register clock muxes */
for (n = 0; desc[n].name;)
n++;
Here n will go out of bounds and then call clk_register_mux() on random
memory contents after the mux clock.
Fix this by terminating the array with a blank entry.

When CPU frequency is at 250 MHz and set_rate() is called with 500 MHz (L1)
quickly followed by a call with 1 GHz (L0), the CPU does not necessarily
stay in L1 for at least 20ms as is required by Marvell errata.
This situation happens frequently with the ondemand cpufreq governor and
can be also reproduced with userspace governor. In most cases it causes CPU
to crash.
This change fixes the above issue and ensures that the CPU always stays in
L1 for at least 20ms when switching from any state to L0.

It was observed that the workaround introduced by commit 61c40f35f5cd
("clk: mvebu: armada-37xx-periph: Fix switching CPU rate from 300Mhz to
1.2GHz") when base CPU frequency is 1.2 GHz is also required when base
CPU frequency is 1 GHz. Otherwise switching CPU frequency directly from
L2 (250 MHz) to L0 (1 GHz) causes a crash.
When base CPU frequency is just 800 MHz no crashed were observed during
switch from L2 to L0.

Remove the .set_parent method in clk_pm_cpu_ops.
This method was supposed to be needed by the armada-37xx-cpufreq driver,
but was never actually called due to wrong assumptions in the cpufreq

needed anymore.

>>> referenced by ap-cpu-clk.c

ap_cp_unique_name is only compiled into the kernel image when
CONFIG_ARMADA_AP_CP_HELPER is selected (as it is not user selectable).
However, CONFIG_ARMADA_AP_CPU_CLK does not select it.
This has been a problem since the driver was added to the kernel but it
was not built before commit c318ea261749 ("cpufreq: ap806: fix cpufreq

Armada 3700 PCIe IP relies on the PCIe clock managed by this
driver. For reasons related to the PCI core's organization when
suspending/resuming, PCI host controller drivers must reconfigure
their registers at suspend_noirq()/resume_noirq() which happens after
suspend()/suspend_late() and before resume_early()/resume().
Device link support in the clock framework enforce that the clock
driver's resume() callback will be called before the PCIe
driver's. But, any resume_noirq() callback will be called before all
the registered resume() callbacks.
The solution to support PCIe resume operation is to change the
"priority" of this clock driver PM callbacks to "_noirq()".

Pull clk updates from Stephen Boyd:
"This round of clk driver and framework updates is heavy on the driver
update side. The two main highlights in the core framework are the
addition of an bulk clk_get API that handles optional clks and an
extra debugfs file that tells the developer about the current parent
of a clk.
The driver updates are dominated by i.MX in the diffstat, but that is
mostly because that SoC has started converting to the clk_hw style of
clk registration. The next big update is in the Amlogic meson clk
driver that gained some support for audio, cpu, and temperature clks
while fixing some PLL issues. Finally, the biggest thing that stands
out is the conversion of a large part of the Allwinner sunxi-ng driver
to the new clk parent scheme that uses less strings and more pointer
comparisons to match clk parents and children up.
In general, it looks like we have a lot of little fixes and tweaks
here and there to clk data along with the normal addition of a handful
of new drivers and a couple new core framework features.
Core:
- Add a 'clk_parent' file in clk debugfs
- Add a clk_bulk_get_optional() API (with devm too)
New Drivers:
- Support gated clk controller on MIPS based BCM63XX SoCs
- Support SiLabs Si5341 and Si5340 chips
- Support for CPU clks on Raspberry Pi devices
- Audsys clock driver for MediaTek MT8516 SoCs
Updates:
- Convert a large portion of the Allwinner sunxi-ng driver to new clk parent scheme
- Small frequency support for SiLabs Si544 chips
- Slow clk support for AT91 SAM9X60 SoCs
- Remove dead code in various clk drivers (-Wunused)
- Support for Marvell 98DX1135 SoCs
- Get duty cycle of generic pwm clks
- Improvement in mmc phase calculation and cleanup of some rate defintions
- Switch i.MX6 and i.MX7 clock drivers to clk_hw based APIs
- Add GPIO, SNVS and GIC clocks for i.MX8 drivers
- Mark imx6sx/ul/ull/sll MMDC_P1_IPG and imx8mm DRAM_APB as critical clock
- Correct imx7ulp nic1_bus_clk and imx8mm audio_pll2_clk clock setting
- Add clks for new Exynos5422 Dynamic Memory Controller driver
- Clock definition for Exynos4412 Mali
- Add CMM (Color Management Module) clocks on Renesas R-Car H3, M3-N, E3, and D3
- Add TPU (Timer Pulse Unit / PWM) clocks on Renesas RZ/G2M
- Support for 32 bit clock IDs in TI's sci-clks for J721e SoCs
- TI clock probing done from DT by default instead of firmware
- Fix Amlogic Meson mpll fractional part and spread sprectrum issues
- Add Amlogic meson8 audio clocks
- Add Amlogic g12a temperature sensors clocks
- Add Amlogic g12a and g12b cpu clocks

These > comparisons should be >= to prevent reading beyond the end of
of the clk_data->hws[] buffer.
The clk_data->hws[] array is allocated in cp110_syscon_common_probe()
when we do:
cp110_clk_data = devm_kzalloc(dev, sizeof(*cp110_clk_data) +
sizeof(struct clk_hw *) * CP110_CLK_NUM,

As you can see, it has CP110_CLK_NUM elements which is equivalent to

Pull clk updates from Stephen Boyd:
"This time it looks like a quieter release cycle in the clk tree. I
guess that's because of summer time holidays/vacations. The biggest
change in the diffstat is in the Qualcomm clk driver, where they got
support for CPUs and handful of SoCs. After that, the at91 driver got
a major rewrite for newer DT bindings that should make things easier
going forward and the TI code moved to a clockdomain based design.
The long tail is mostly small driver updates for newer clks and some
simpler SoC clock drivers such as the Hisilicon and imx support.
In the core framework, we only have two small changes this time.
One is a new clk API to get all clks for a device with the bulk clk
APIs. This allows drivers that don't care about doing anything besides
turning on all the clks to just clk_get() them all and turn them on.
The other change is the beginning of a way to support save and restore
of clk settings in the clk framework. TI is the only user right now,
but we will want to expand upon this design in the future to support
more save and restore of clk registers. At least this gets us started
and works well enough for one SoC, but there's more work in the
future.

The parent clock is get only to have its name, and then the clock is no
more used, so we can safely free it using clk_put. Furthermore as between
the successful devm_clk_get() and the devm_clk_put() call we don't exit
the probe function in error so I can use non managed version of clk_get()
and clk_put().

Add suspend/resume hooks in Armada 37xx peripheral clocks driver to
handle S2RAM operations.
One can think that these hooks are useless by comparing the register
values before and after a suspend/resume cycle: they will look the same
anyway. This is because of some scripts executed by the Cortex-M3 core
during ATF operations to init both the clocks and the DDR. These values
could be modified by the BL33 stage or by Linux itself and should be
preserved.

Pull clk updates from Stephen Boyd:
"The new and exciting feature this time around is in the clk core.
We've added duty cycle support to the clk API so that clk signal duty
cycle ratios can be adjusted while taking into account things like clk
dividers and clk tree hierarchy. So far only one SoC has implemented
support for this, but I expect there will be more to come in the
future.
Outside of the core, we have the usual pile of clk driver updates and
additions. The Amlogic meson driver got the most lines in the diffstat
this time around because it added support for a whole bunch of
hardware and duty cycle configuration. After that the Rockchip PX30,
Qualcomm SDM845, and Renesas SoC drivers fill in a majority of the
diff. We're left with the collection of non-critical fixes after that.
Overall it looks pretty quiet this time.
Core:
- Clk duty cycle support
- Proper CLK_SET_RATE_GATE support throughout the tree
New Drivers:
- Actions Semi Owl series S700 SoC clk driver
- Qualcomm SDM845 display clock controller
- i.MX6SX ocram_s clk support
- Uniphier NAND, USB3 PHY, and SPI clk support
- Qualcomm RPMh clk driver
- i.MX7D mailbox clk support
- Maxim 9485 Programmable Clock Generator
- expose 32 kHz PLL on PXA SoCs
- imx6sll GPIO clk gate support
- Atmel at91 I2S audio clk support
- SI544/SI514 clk on/off support
- i.MX6UL GPIO clock gates in CCM CCGR
- Renesas Crypto Engine clocks on R-Car H3
- Renesas clk support for the new RZ/N1D SoC
- Allwinner A64 display engine clock support
- support for Rockchip's PX30 SoC
- Amlogic Meson axg PCIe and audio clocks
- Amlogic Meson GEN CLK on gxbb, gxl and axg
Updates:
- remove an unused variable from Exynos4412 ISP driver

- add missing of_node_put()s in some i.MX clk drivers
- Tegra SDMMC clk jitter improvements with high speed signaling modes
- SPDX tagging for qcom and cs2000-cp drivers
- stop leaking con ids in __clk_put()
- fix a corner case in fixed factor clk probing where node is in DT
but parent clk is registered much later

When building armada-37xx-periph, num_parents isn't used in function
clk_pm_cpu_get_parent:
drivers/clk/mvebu/armada-37xx-periph.c: In function ‘clk_pm_cpu_get_parent’:
drivers/clk/mvebu/armada-37xx-periph.c:419:6: warning: unused variable ‘num_parents’ [-Wunused-variable]
int num_parents = clk_hw_get_num_parents(hw);
^~~~~~~~~~~
Remove the declaration of num_parents to dispose the warning.

The return value of the get_parent operation is a u8, whereas a -EINVAL
was returned. This wrong value was return if the value was bigger that
the number of parent but this case was already handled by the core.
So we can just remove this chunk of code to fix the issue.
