The clock controller is located in a register range (called "HHI") which
contains more than just registers for the clock controller. Known
consumers of the HHI register range are:
- the clock controller
- a reset controller
- temperature sensor calibration coefficient (TSC) (only on Meson8b and
Meson8m2)
- HDMI controller
The main reason for using a syscon is the "temperature sensor
calibration coefficient" which has to be set for the built-in temperature
sensor to work correctly. Four TSC bits are located in the SAR ADC's
register space. However on Meson8b and Meson8m2 there is a fifth TSC bit
which is unfortunately located in the HHI register space. To be more
precise, bit 9 of the HHI_DPLL_TOP_0 register (which sits right between
the HHI_SYS_PLL and HHI_VID_PLL registers).
Get the regmap from the parent (HHI syscon) node to support all
functionality of the HHI register range. Backwards compatibility with
old .dtbs is ensured by falling back to parsing the registers just like
before this change.

Add the clocks entries used in the video clock path, the clock path
is doubled to permit having different synchronized clocks for different
parts of the video pipeline.
All dividers are flagged with CLK_GET_RATE_NOCACHE, and all gates are flagged
with CLK_IGNORE_UNUSED since they are currently directly handled by the
Meson DRM Driver.
Once the DRM Driver is fully migrated to using the Common Clock Framework
to handle the video clock tree, the CLK_GET_RATE_NOCACHE and CLK_IGNORE_UNUSED
will be dropped.

In an attempt to better describe the HDMI PLL, a single DCO clock was
left for GXBB and GXL, but the GXL DCO does not have a pre-multiplier.

Certain firmware configurations "protect" clks and cause the entire
system to reboot when a non-secure OS such as Linux tries to read or
write protected clk registers. But other firmware configurations allow
reading or writing the same registers, and they may actually require
that the OS use the otherwise locked down clks. Support the
'protected-clocks' property by never registering these protected clks
with the common clk framework. This way, when firmware is protecting
these clks we won't have the chance to ever read or write these
registers and take down the entire system.

The "security processor", sometimes referred to as "wireless trusted
module" or "generic encrypt unit" is a low-power core present on MMP2,
that has nothing to do with security, wireless, trust or encryption.
On an OLPC machine it runs CForth and serves as a keyboard controller:
http://dev.laptop.org/git/users/wmb/cforth/tree/src/app/arm-xo-1.75/ps2.fth
The register address was obtained from the OLPC kernel, since the
datasheet seems to be the Marvell's most important business secret.

On the Khadas VIM2 (GXM) and LePotato (GXL) board there are problems
with reboot; e.g. a ~60 second delay between issuing reboot and the
board power cycling (and in some OS configurations reboot will fail
and require manual power cycling).
Similar to 'commit c987ac6f1f088663b6dad39281071aeb31d450a8 ("clk:
meson-gxbb: set fclk_div2 as CLK_IS_CRITICAL")' the SCPI Cortex-M4
Co-Processor seems to depend on FCLK_DIV3 being operational.
Until commit 05f814402d6174369b3b29832cbb5eb5ed287059 ("clk:
meson: add fdiv clock gates"), this clock was modeled and left on by
the bootloader.
We don't have precise documentation about the SCPI Co-Processor and
its clock requirement so we are learning things the hard way.
Marking this clock as critical solves the problem but it should not
be viewed as final solution. Ideally, the SCPI driver should claim
these clocks. We also depends on some clock hand-off mechanism
making its way to CCF, to make sure the clock stays on between its
registration and the SCPI driver probe.

Currently MP clocks don't consider adjusting parent rate even if they
are allowed to do so. Such behaviour considerably lowers amount of
possible rates, which is very inconvenient when such clock is used for
pixel clock, for example.
In order to improve the situation, adjusting parent rate is considered
when allowed.
This code is inspired by clk_divider_bestdiv() function, which does
basically the same thing for different clock type.

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.

When a memblock allocation APIs are called with align = 0, the alignment
is implicitly set to SMP_CACHE_BYTES.
Implicit alignment is done deep in the memblock allocator and it can
come as a surprise. Not that such an alignment would be wrong even
when used incorrectly but it is better to be explicit for the sake of
clarity and the prinicple of the least surprise.
Replace all such uses of memblock APIs with the 'align' parameter
explicitly set to SMP_CACHE_BYTES and stop implicit alignment assignment
in the memblock internal allocation functions.
For the case when memblock APIs are used via helper functions, e.g. like
iommu_arena_new_node() in Alpha, the helper functions were detected with
Coccinelle's help and then manually examined and updated where
appropriate.
The direct memblock APIs users were updated using the semantic patch below:

Pull ARM SoC driver updates from Arnd Bergmann:
"The most noteworthy SoC driver changes this time include:
- The TEE subsystem gains an in-kernel interface to access the TEE
from device drivers.
- The reset controller subsystem gains a driver for the Qualcomm
Snapdragon 845 Power Domain Controller.
- The Xilinx Zynq platform now has a firmware interface for its
platform management unit. This contains a firmware "ioctl"
interface that was a little controversial at first, but the version
we merged solved that by not exposing arbitrary firmware calls to
user space.
- The Amlogic Meson platform gains a "canvas" driver that is used for
video processing and shared between different high-level drivers.
The rest is more of the usual, mostly related to SoC specific power
management support and core drivers in drivers/soc:
- Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
features related to power and reset control.
- The Mediatek mt8183 and mt6765 SoC platforms gain support for their
respective power management chips.
- A new driver for NXP i.MX8, which need a firmware interface for
power management.
- The SCPI firmware interface now contains support estimating power
usage of performance states
- The NVIDIA Tegra "pmc" driver gains a few new features, in
particular a pinctrl interface for configuring the pads.
- Lots of small changes for Qualcomm, in particular the "smem" device
driver.
- Some cleanups for the TI OMAP series related to their sysc
controller.
Additional cleanups and bugfixes in SoC specific drivers include the
Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms"

Pull Devicetree updates from Rob Herring:
"A bit bigger than normal as I've been busy this cycle.
There's a few things with dependencies and a few things subsystem
maintainers didn't pick up, so I'm taking them thru my tree.
The fixes from Johan didn't get into linux-next, but they've been
waiting for some time now and they are what's left of what subsystem
maintainers didn't pick up.
Summary:
- Sync dtc with upstream version v1.4.7-14-gc86da84d30e4
- Work to get rid of direct accesses to struct device_node name and
type pointers in preparation for removing them. New helpers for
parsing DT cpu nodes and conversions to use the helpers. printk
conversions to %pOFn for printing DT node names. Most went thru
subystem trees, so this is the remainder.
- Fixes to DT child node lookups to actually be restricted to child
nodes instead of treewide.
- Refactoring of dtb targets out of arch code. This makes the support
more uniform and enables building all dtbs on c6x, microblaze, and
powerpc.
- Various DT binding updates for Renesas r8a7744 SoC
- Vendor prefixes for Facebook, OLPC
- Restructuring of some ARM binding docs moving some peripheral
bindings out of board/SoC binding files
- New "secure-chosen" binding for secure world settings on ARM
- Dual licensing of 2 DT IRQ binding headers"
