This adds a new driver for mach-davinci PSC clocks. This is porting the
code from arch/arm/mach-davinci/psc.c to the common clock framework and
is converting it to use regmap to simplify the code. Additionally, it
adds device tree support for these clocks.
Note: although there are similar clocks for TI Keystone we are not able
to share the code for a few reasons. The keystone clocks are device tree
only and use legacy one-node-per-clock bindings. Also the keystone
driver makes the assumption that there is only one PSC per SoC and uses
global variables, but here we have two controllers per SoC.

This adds a new driver for mach-davinci PLL clocks. This is porting the
code from arch/arm/mach-davinci/clock.c to the common clock framework.
Additionally, it adds device tree support for these clocks.
The ifeq ($(CONFIG_COMMON_CLK), y) in the Makefile is needed to prevent
compile errors until the clock code in arch/arm/mach-davinci is removed.
Note: although there are similar clocks for TI Keystone we are not able
to share the code for a few reasons. The keystone clocks are device tree
only and use legacy one-node-per-clock bindings. Also the register
layouts are a bit different, which would add even more if/else mess
to the keystone clocks. And the keystone PLL driver doesn't support
setting clock rates.

Commit aa795c41d9cd ("clk: Add devm_of_clk_add_hw_provider()/del_provider()
APIs") adds devm_of_clk_add_hw_provider which takes care of deleting the
clock provider when the clock providers device is removed.
This patch makes use of devm_of_clk_add_hw_provider() instead of
of_clk_add_hw_provider() so that we can eliminate the need of explicit
scmi_clocks_remove for just doing of_clk_del_provider()

For upcoming targets like sdm845, POR value of the hardware clock control
bit is set for most of root clocks which needs to be cleared for software
to be able to control. For older targets like MSM8996, this bit is reserved
bit and having POR value as 0 so this patch will work for the older targets
too. So update the configuration mask to take care of the same to clear

It's found that the clock phase output from clk_summary is
wrong compared to the actual phase reading from the register.
cat /sys/kernel/debug/clk/clk_summary | grep sdio_sample
sdio_sample 0 1 0 50000000 0 -22
It exposes an issue that clk core, clk_core_get_phase, always
returns the cached core->phase which should be either updated
by calling clk_set_phase or directly from the first place the
clk was registered.
When registering the clk, the core->phase geting from ->get_phase()
may return negative value indicating error. This is quite common
since the clk's phase may be highly related to its parent chain,
but it was temporarily orphan when registered, since its parent
chains hadn't be ready at that time, so the clk drivers decide to
return error in this case. However, if no clk_set_phase is called or
maybe the ->set_phase() isn't even implemented, the core->phase would
never be updated. This is wrong, and we should try to update it when
all its parent chains are settled down, like the way of updating clock
rate for that. But it's not deserved to complicate the code now and
just update it anyway when calling clk_core_get_phase, which would be
much simple and enough.

Clearfog boards can come with a CPU clocked at 1600MHz (commercial)
or 1333MHz (industrial).
They have also some dip-switches to select a different clock (666, 800,
1066, 1200).
The funny thing is that the recovery button is on the MPP34 fq selector.
So, when booting an industrial board with this button down, the frequency
666MHz is selected (and the kernel didn't boot).
This patch add all the missing clocks.
The only mode I didn't test is 2GHz (uboot found 4294MHz instead :/ ).

When changing or retrieving clock parents, the caller is in a sleepable
state (like prepare) so the GPIO operation need not be atomic. Replace
gpiod_{g|s}et_value with gpiod_{g|s}et_value_cansleep in the {g|s}et_parent
calls for the GPIO based clock mux.
This fixes a "slowpath" warning when the GPIO controller is an I2C expander
or something similar.

The clock for which all PWM devices on MT7623 or MT2701 actually depending
on has to be divided by four from its parent clock axi_sel in the clock
path prior to PWM devices.
Consequently, adding a fixed-factor clock axisel_d4 as one-fourth of
clock axi_sel allows that PWM devices can have the correct resolution
calculation.

Thanks to new documentation, we have a better view of the clock tree.
There were few mistakes in the first version of this driver, the main one
being the parental link between the clocks. Actually the tree is more
flat that we though. Most of the IP blocks require two clocks: one for
the IP itself and one for accessing the registers, and unlike what we
wrote there is no link between these two clocks.
The other mistakes were about the name of the clocks: the root clock is
not the Audio PLL but the PLL0, and what we called the EIP clock is named
the x2 Core clock and is used by other IP block than the EIP ones.

Note that this commit fixes a long standing bug preventing one from
using an HDMI display if it's plugged after the FW has booted Linux.
This is because PLLH is used by the HDMI encoder to generate the pixel

When we build this driver with on x86-32, gcc produces a false-positive warning:
drivers/clk/renesas/clk-sh73a0.c: In function 'sh73a0_cpg_clocks_init':
drivers/clk/renesas/clk-sh73a0.c:155:10: error: 'parent_name' may be used uninitialized in this function [-Werror=maybe-uninitialized]
return clk_register_fixed_factor(NULL, name, parent_name, 0,
We can work around that warning by adding a fake initialization, I tried
and failed to come up with any better workaround. This is currently one
of few remaining warnings for a 4.14.y randconfig build, so it would be
good to also have it backported at least to that version. Older versions
have more randconfig warnings, so we might not care.
I had not noticed this earlier, because one patch in my randconfig test
tree removes the '-ffreestanding' option on x86-32, and that avoids
the warning. The -ffreestanding flag was originally global but moved
into arch/i386 by Andi Kleen in commit 6edfba1b33c7 ("[PATCH] x86_64:
Don't define string functions to builtin") as a 'temporary workaround'.
Like many temporary hacks, this turned out to be rather long-lived, from
all I can tell we still need a simple fix to asm/string_32.h before it
can be removed, but I'm not sure about how to best do that.

clk_round_rate() is intended to be used to round a given clock rate to
the closest one achievable by the actual clock. This implies that the
input to clk_round_rate() is expected to be unachievable - and such
cases shouldn't be treated as exceptional.
To reflect this, remove the WARN_ONs which trigger when an unachievable
clock rate is passed to vexpress_osc_round_rate().

According to the Aspeed specification, the reset and enable sequence
should be done when the clock is stopped. The specification doesn't
define behavior if the reset is done while the clock is enabled.
From testing on the AST2500, the LPC Controller has problems if the
clock is reset while enabled.
Therefore, check whether the clock is enabled or not before performing
the reset and enable sequence in the Aspeed clock driver.

Some of the Aspeed clocks are disabled by setting the relevant bit in
the "clock stop control" register to one, while others are disabled by
setting their bit to zero. The driver already uses a flag per gate to
identify this behavior, but doesn't apply it in the clock is_enabled
function.
Use the existing gate flag to correctly return whether or not a clock
is enabled in the aspeed_clk_is_enabled function.

Pull i.MX clock misc updates from Shawn Guo:
- A correction on i.MX6SX CKO clock mux options.
- A fix on i.MX7D Video PLL clock tree to include the missing dividers.
- Update i.MX6UL/ULL clock driver to add epdc_podf instead of sim_podf
clock for i.MX6ULL.
