With the new clk parenting code and CLK_FIXED_FACTOR_{HW,FW_NAME}
macros, we can reference parents locally via pointers to struct clk_hw
or DT clock-names.
Convert existing CLK_FIXED_FACTOR definitions to either the _HW or
_FW_NAME variant based on whether the parent clock is internal or
external to the CCU.

With the new clk parenting code and CLK_HW_INIT_* macros, we can
reference parents locally via pointers to struct clk_hw or DT
clock-names.
Convert existing CLK_HW_INIT_* definitions to describe parents using
either struct clk_hw pointers or clock-names from the device tree
binding.
For the AR100, this also allows us to merge the generic AR100 and the
A83T specific one, which only differed in the global clock names for
their parent clocks. The device tree bindings used the same name
specifiers.

Commit 89a5ddcc799d ("clk: Add of_clk_hw_register() API for early clk
drivers") introduces a new API for registering clks, which allows the
user to directly specify a device node, even if there is no struct
device attached to it. The device node is used for local DT clock-names
matching.
Switch to of_clk_hw_register() so that local DT clock-names matching
works.

With the new clk parenting code, clk_init_data was expanded to include
.parent_data, for clk drivers to specify parents using a combination of
device tree clock-names, pointers to struct clk_hw, device tree clocks,
and/or fallback global clock names.
Add a new macro, CLK_FIXED_FACTOR_FW_NAME, that takes a string to match
a clock-names entry in the device tree to specify the clock parent.

Add a new macro, CLK_FIXED_FACTOR_HWS, that can take an array of pointers
to struct clk_hw, instead of a string, as its parent. Taking an array
instead of a direct pointer allows the reuse of the array for multiple

allocated for each clk declaration.

With the new clk parenting code, struct clk_init_data was expanded to
include .parent_hws, for clk drivers to directly list parents by
pointing to their respective struct clk_hw's.
Add macros that can take either one single struct clk_hw *, or an array

A special CLK_HW_INIT_HWS macro is included, which takes an array of
struct clk_hw *, but sets .num_parents to 1. This variant is to allow
the reuse of the array, instead of having a compound literal allocated
for each clk sharing the same parent.

Following the commit fc0c209c147f ("clk: Allow parents to be specified
without string names"), the parent name string is not always populated.
Instead, fetch the parents clk_core struct using the appropriate helper,
and read its name directly. If that fails, go through the possible
sources of parent names. The order in which they are used is different
from how parents are looked up, with the global name having precedence
over local fw_name and indices. This makes more sense as a) the
parent_maps structure does not differentiate between legacy global names
and fallback global names, and b) global names likely provide more
information than local fw_names.

Future SoCs are going to have more than 255 device clocks in certain cases,
and thus the API must be extended to support this. The support is done in
backwards compatible extension, in which the new u32 clock identifier
fields are only used if the existing u8 size clock identifier is set as
255. In all the other cases, the existing u8 clock identifier is used. As
the size of the messages sent / received is not verified for existing
devices / old firmware, increasing the size of the messages from the end
is also fine. Due to this reason, depending on ABI version isn't necessary
either.

Update the Meson G12A Clock driver to support the Amlogic G12B SoC.
G12B clock driver is very close, the main differences are :
- the clock tree is duplicated for the both clusters, and the
SYS_PLL are swapped between the clusters
- G12B has additional clocks like for CSI an other components
Here only the cpu clock tree is handled.

Add the cts_i958 clock to control the clock source of the spdif output
block. It is used to select whether the clock source of the spdif output
is cts_amclk (when data are taken from i2s buffer) or the cts_mclk_i958

The code was setting the bit 21 of the CPCCR register to use a divider
of 2 for the "pll half" clock, and clearing the bit to use a divider
of 1.
This is the opposite of how this register field works: a cleared bit
means that the /2 divider is used, and a set bit means that the divider
is 1.
Restore the correct behaviour using the newly introduced .div_table
field.

Some clocks provided on Ingenic SoCs have dividers, whose hardware value
as written in the register cannot be expressed as an affine function
to the actual divider value.
For instance, for the CPU clock on the JZ4770, the dividers are coded as
follows:
------------------
| Bits | Div |
------------------
| 0 0 0 | 1 |
| 0 0 1 | 2 |
| 0 1 0 | 3 |
| 0 1 1 | 4 |
| 1 0 0 | 6 |
| 1 0 1 | 8 |
| 1 1 0 | 12 |
------------------
To support this setup, we introduce a new field in the
ingenic_cgu_div_info structure that allows to specify the divider table.

Currently, the clock identifiers are limited to 255. To support future
SoCs, this muse be extended to 32 bits, which should provide way more
than enough space. Basic support for extending the clock API is going
to be implemented in the firmware driver, but there are some minor
changes that need to be done on the clock driver side first.
