Some bcm2835 clocks used by hardware (like "PWM" or "H264") can have multiple
parent clocks. These clocks divide the rate of a parent which can be selected by
setting the proper bits in the clock control register.
Previously all these parents where handled by a mux clock. But a mux clock
cannot be used because updating clock control register to select parent needs a
password to be xor'd with the parent index.
This patch get rid of mux clock and make these clocks handle their own parent,
allowing them to select the one to use.

This adds support for enabling, disabling, and setting the rate of the
audio domain clocks. It will be necessary for setting the pixel clock
for HDMI in the VC4 driver and let us write a cpufreq driver. It will
also improve compatibility with user changes to the firmware's
config.txt, since our previous fixed clocks are unaware of it.
The firmware also has support for configuring the clocks through the
mailbox channel, but the pixel clock setup by the firmware doesn't
work, and it's Raspberry Pi specific anyway. The only conflicts we
should have with the firmware would be if we made firmware calls that
result in clock management (like opening firmware V3D or ISP access,
which we don't support in upstream), or on hardware over-thermal or
under-voltage (when the firmware would rewrite PLLB to take the ARM
out of overclock). If that happens, our cached .recalc_rate() results
would be incorrect, but that's no worse than our current state where
we used fixed clocks.
The existing fixed clocks in the code are left in place to provide
backwards compatibility with old device tree files.

Rather than "manually" setting up each CCU's clock entries at run
time, define a flexible array of generic Kona clock structures
within the CCU structure itself. Each of these entries contains
generic kona clock information (like its CCU pointer and clock
framework initialization data). Each also has a pointer to a
structure contianing clock type-dependent initialization data
(like register definitions).
Since we'll iterate over these arrays we need to be sure they have
slots for all potential clock index values. (E.g. for the root CCU
we must have at least BCM281XX_ROOT_CCU_CLOCK_COUNT slots.) To
ensure this we always define an extra entry and fill it using the
special initializer LAST_KONA_CLK.
Just about everything we need to know about a clock can be defined
statically. As a result, kona_clk_setup() can be changed to take
just a kona_clk structure as its argument, and peri_clk_setup() can
be simplified. With the information pre-defined we are also able
to handle most clock setup genericially. We can do away with the
CCU-specific callback functions that previously were needed to set
up the entries in CCU's clock array.

We also know at build time how many clocks a given CCU will provide,
though the number of of them for each CCU is different. Record the
number of clocks we need in the CCU's clk_onecell_data struct
(which is used when we register the CCU with the common clock code
as a clock provider). Rename that struct field "clk_data" (because
"data" alone gets a little confusing).
Use the known clock count to move the allocation of each CCU's
clocks array into ccu_clks_setup() rather than having each CCU's

As I developed the bcm281xx clock code I understood there were
restrictions on device tree "compatible" strings names, and as a
result "bcm11351" was used in places despite the part family being
more properly called "bcm281xx". This can be a little confusing.
In some cases I went to far and things using "bcm11351" when that
was not necessary.
This patch remedies this. It renames the symbol used to define the

Add code for device tree support of clocks in the BCM281xx family of
SoCs. Machines in this family use peripheral clocks implemented by
"Kona" clock control units (CCUs). (Other Broadcom SoC families use
Kona style CCUs as well, but support for them is not yet upstream.)
A BCM281xx SoC has multiple CCUs, each of which manages a set of
clocks on the SoC. A Kona peripheral clock is composite clock that
may include a gate, a parent clock multiplexor, and zero, one
or two dividers. There is a variety of gate types, and many gates
implement hardware-managed gating (often called "auto-gating").
Most dividers divide their input clock signal by an integer value
(one or more). There are also "fractional" dividers which allow
division by non-integer values. To accomodate such dividers,
clock rates and dividers are generally maintained by the code in
"scaled" form, which allows integer and fractional dividers to
be handled in a uniform way.
If present, the gate for a Kona peripheral clock must be enabled
when a change is made to its multiplexor or one of its dividers.
Additionally, dividers and multiplexors have trigger registers which
must be used whenever the divider value or selected parent clock is
changed. The same trigger is often used for a divider and
multiplexor, and a BCM281xx peripheral clock occasionally has two
triggers.
The gate, dividers, and parent clock selector are treated in this
code as "components" of a peripheral clock. Their functionality is
implemented directly--e.g. the common clock framework gate
implementation is not used for a Kona peripheral clock gate. (This
has being considered though, and the intention is to evolve this
code to leverage common code as much as possible.)
The source code is divided into three general portions:
drivers/clk/bcm/clk-kona.h
drivers/clk/bcm/clk-kona.c
These implement the basic Kona clock functionality,
including the clk_ops methods and various routines to
manipulate registers and interpret their values. This
includes some functions used to set clocks to a desired
initial state (though this feature is only partially
implemented here).
drivers/clk/bcm/clk-kona-setup.c
This contains generic run-time initialization code for
data structures representing Kona CCUs and clocks. This
encapsulates the clock structure initialization that can't
be done statically. Note that there is a great deal of
validity-checking code here, making explicit certain
assumptions in the code. This is mostly useful for adding
new clock definitions and could possibly be disabled for
production use.
drivers/clk/bcm/clk-bcm281xx.c
This file defines the specific CCUs used by BCM281XX family
SoCs, as well as the specific clocks implemented by each.
It declares a device tree clock match entry for each CCU
defined.
include/dt-bindings/clock/bcm281xx.h
This file defines the selector (index) values used to
identify a particular clock provided by a CCU. It consists
entirely of C preprocessor constants, to be used by both the
