Add a driver for the clocks provided by the MIPS Boston board from
Imagination Technologies. 2 clocks are provided - the system clock & the
CPU clock - and each is a simple fixed rate clock whose frequency can be
determined by reading a register provided by the board.

Current implementation of scpi_clk_add just print a warning when clock
fails to register but then keep going as if nothing happened. The
provider is then registered with bogus data.
This may latter lead to an Oops in __clk_create_clk when
hlist_add_head(&clk->clks_node, &hw->core->clks) is called.
This patch fixes the issue and errors if a clock fails to register.

CONFIG_COMPILE_TEST allows building a configuration without
TI_SCI_PROTOCOL, which then fails to link:
drivers/clk/keystone/sci-clk.o: In function `ti_sci_clk_probe':
sci-clk.c:(.text.ti_sci_clk_probe+0x4c): undefined reference to `devm_ti_sci_get_handle'
This makes it a hard dependency. Right now, that means we can't
actually compile-test the driver unless ARCH_KEYSTONE is set as
well, but we can fix that by allowing TI_MESSAGE_MANAGER to
be selected for COMPILE_TEST as well.

Similarly to commit f1e9203e2366 ("clk: samsung: Fix Exynos 5420 pinctrl
setup and clock disable failure due to domain being gated") for
Exynos5420, the Exynos4412 also requires that EPLL is not disabled.
Otherwise any access to MAUDIO block will silently halt.
This was not visible before because EPLL on Exynos4 could not be
disabled before commit 6edfa11cb396 ("clk: samsung:
Add enable/disable operation for PLL36XX clocks"). After this commit,
on Odroid U3 board one can see silent hang, usually with last (but

controller that derive all clocks from a single crystal, using some
documented and some undocumented PLLs, half dividers, counters and
gates. This is a best attempt to construct a clock driver for the
clocks so at least we can gate off unused hardware and driver the

and NAND_CLK_ROOT. However, the gate has been in the chain of the
latter only. This does not allow to use the NAND_USDHC_BUS_CLK_ROOT
only, e.g. as required by APBH-Bridge-DMA.

shared clock gate to correctly model the hardware.

The timer will register into system at very early phase at kernel boot;
if timer needs to use clock, the clock should be get ready in function
of_clk_init() so later the timer driver probe can retrieve clock
successfully. This is finished in below flow on arm64:
start_kernel()
`-> time_init()
`-> of_clk_init(NULL) => register timer's clock
`-> clocksource_probe() => register timer
On Hi3660 the sp804 timer uses clock "osc32k", this clock is registered
as platform driver rather than CLK_OF_DECLARE_DRIVER method. As result,
sp804 timer probe returns failure due if cannot bind clock properly.
To fix the failure, this patch is to split crgctrl clocks into two
subsets. One part is for fixed_rate_clks which includes pre-defined
fixed rate clocks, and "osc32k" clock is in this category; So we change
their registration to CLK_OF_DECLARE_DRIVER method, as result the clocks
can be registered ahead with function of_clk_init() and timer driver can
bind timer clock successfully; the rest of the crgctrl clocks are still
registered by the probe of the platform driver.
This patch also adds checking for all crgctrl clocks registration and
print out log if any clock has failure.

This commit updates the CP110 system controller driver to add the
definition for a missing clock.
The SDIO clock is dedicated driving the SDHCI interface and its frequency
is 400MHz (2/5 of PLL source clock).
The SDIO interface should be bound to this clock and not the core clock
as in the older code.
Using the wrong clock lead to a maximum SDHCI frequency of 250 Mhz, while
the HW really supports up to 400 Mhz.
This patch also fixes the NAND clock relationship documentation.

The initial intent when the binding of the cp110 system controller was to
have one flat node. The idea being that what is currently a clock-only
driver in drivers would become a MFD driver, exposing the clock, GPIO and
pinctrl functionality. However, after taking a step back, this would lead
to a messy binding. Indeed, a single node would be a GPIO controller,
clock controller, pinmux controller, and more.
This patch adopts a more classical solution of a top-level syscon node
with sub-nodes for the individual devices. The main benefit will be to
have each functional block associated to its own sub-node where we can
put its own properties.
The introduction of the Armada 7K/8K is still in the early stage so the
plan is to remove the old binding. However, we don't want to break the
device tree compatibility for the few devices already in the field. For
this we still keep the support of the legacy compatible string with a big
warning in the kernel about updating the device tree.

Using the *-clock-output-names property was a convenient way to have a
unique name for each clock even when there are multiple cp110 blocks
as we can find on Armada 8K.
However it has some drawbacks: the main one being a stronger link than
necessary between the driver and the device tree. For example the clock
name can't be changed, removed or moved. It is still the early stage of
introduction of the Armada 7K/8K and the hardware is still not totally
documented, especially for the clock part. By removing the use of
*-clock-output-names it will be easier to add new clocks without breaking
the compatibility.
The name of each clock is now created by using its physical address as a
prefix (as it was done for the platform device names). Thanks to this we
have an automatic way to compute a unique name.

In K2G, the clock handling is done through firmware executing on a
separate core. Linux kernel needs to communicate to the firmware
through TI system control interface to access any power management
related resources, including clocks.
The keystone sci-clk driver does this, by communicating to the
firmware through the TI SCI driver. The driver adds support for
registering clocks through DT, and basic required clock operations
like prepare/get_rate, etc.

The clock controller on Meson8, Meson8b and Meson8m2 is very similar
based on the code from the Amlogic GPL kernel sources. Add separate
compatibles for each SoC to make sure that we can easily implement
all the small differences for each SoC later on.
In general the Meson8 and Meson8m2 seem to be almost identical as they
even share the same mach-meson8 directory in Amlogic's GPL kernel
sources.
The main clocks on Meson8, Meson8b and Meson8m2 are very similar,
because they are all using the same PLL values, 90% of the clock gates
are the same (the actual diffstat of the mach-meson8/clock.c and
mach-meson8b/clock.c files is around 30 to 40 lines, when excluding
all commented out code).
The difference between the Meson8 and Meson8b clock gates seem to be:
- Meson8 has AIU_PCLK, HDMI_RX, VCLK2_ENCT, VCLK2_ENCL, UART3,
CSI_DIG_CLKIN gates which don't seem to be available on Meson8b
- the gate on Meson8 for bit 7 seems to be named "_1200XXX" instead
of "PERIPHS_TOP" (on Meson8b)
- Meson8b has a SANA gate which doesn't seem to exist on Meson8 (or
on Meson8 the same bit is used by the UART3 gate in Amlogic's GPL
kernel sources)
None of these gates is added for now, since it's unclear whether these
definitions are actually correct (the VCLK2_ENCT gate for example is
defined, but only used in some commented block).
The main difference between all three SoCs seem to be the video (VPU)
clocks. Apart from different supported clock rates (according to vpu.c
in mach-meson8 and mach-meson8b from Amlogic's GPL kernel sources) the
most notable difference is that Meson8m2 has a GP_PLL clock and a mux
(probably the same as on the Meson GX SoCs) to support glitch-free
(clock rate) switching.
None of these VPU clocks are not supported by our mainline meson8b
clock driver yet though.
