clk registration by clk providers and debugfs "nice to haves" for rate
constraints. I'll highlight that we're now setting the clk_init_data pointer
inside struct clk_hw to NULL during clk_register(), which may break some
drivers that thought they could use that pointer during normal operations. That
change has been sitting in next for a while now but maybe something is still
broken. We'l see. Other than that the core framework changes aren't invasive
and they're fixing bugs, simplifying, and making things better.
On the clk driver side we got the usual addition of new SoC support, new
features for existing drivers, and bug fixes scattered throughout. The biggest
diffstat is the Amlogic driver that gained CPU clk support in addition to
migrating to the new way of specifying clk parents. After that the Qualcomm,
i.MX, Mediatek, and Rockchip clk drivers got support for various new SoCs and
clock controllers from those vendors.
Core:
- Drop NULL checks in clk debugfs
- Add min/max rates to clk debugfs
- Set clk_init_data pointer inside clk_hw to NULL after registration
- Make clk_bulk_get_all() return an 'id' corresponding to clock-names
- Evict parents from parent cache when they're unregistered
New Drivers:
- Add clock driver for i.MX8MN SoCs
- Support aspeed AST2600 SoCs
- Support for Mediatek MT6779 SoCs

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.

Some modules may need to change its clock rate before turn on it.
So changing PLL's rate when it is off should be allowed.
This patch removes PLL enabled check before set rate, so that
PLLs can set new frequency even if they are off.
On MT8173 for example, ARMPLL's enable bit can be controlled by
other HW. That means ARMPLL may be turned on even if we (CPU / SW)
set ARMPLL's enable bit as 0. In this case, SW may want and can
still change ARMPLL's rate by changing its pcw and postdiv settings.
But without this patch, new pcw setting will not be applied because
its enable bit is 0.

However, the pcw change bit on MT8183 was moved onto CON0 because

We could add this flag to enable this function of MUX in CCF.

This function is called from driver probe, which isn't the same as
__init code because driver probe can happen later. Drop the __init

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.

Changes from v1->v2:
Add 'select RESET_CONTROLLER' under COMMON_CLK_MEDIATEK and enable
reset.c to be built when COMMON_CLK_MEDIATEK is selected. That should
be quite reasonable because the reset controller is tightly embedded
inside and exported from these clock subsystems. At least it can be found
on infracfg and pericfg subsystem that both are really fundamental block
lots of devices must depend on.
commit 74cb0d6dde ("clk: mediatek: fixup test-building of MediaTek clock
drivers") can let the build system looking into the directory where the
clock drivers resides and then allow test-building the drivers.
But the change also gives rise to certain incorrect behavior which is
reset.c being built even not depending on either COMPILE_TEST or
ARCH_MEDIATEK alternative dependency. To get rid of reset.c being built
unexpectedly on the other platforms, it would be a good change that the
file should be built depending on its own specific configuration rather
than just on generic RESET_CONTROLLER one.

Even though the header file linux/clk-provider.h is already being properly
included in clk-mtk.h, the definition of struct clk_onecell_data still
must depend on CONFIG_COMMON_CLK defined and thus it's possible that
below build warnings occur when CONFIG_COMMON_CLK is not being selected.
Therefore, these functions which need struct clk_onecell_data without
declaring that structure first requires simply declaring that this struct
exists prior to referencing it in clk-mtk.h
Changes from v1->v2:
enhance v1 based on two useful solutions Jean Delvare kindly suggested.
