These functions are only used within clock-pcom.c, therefore mark
them as static.

If the array of clk_lookups contains aliases for the same struct
clk, msm_clock_init() will add the clock to the clocks list
twice. This would cause list corruption so let's just remove the
clocks list and any associated code and iterate over the array
instead.

This means you'll end up calling clock_debug_add() twice for the same
struct clk - this sounds like a bad idea in itself. It looks like
there's no protection within that function against it being called
twice with the same struct clk.
Are you sure this is safe?

This hasn't proven to be a problem so far because debugfs returns an
error when you create a directory with the same name twice. If we ever
do something more in clock_debug_add() we would have a problem.

Move the unsigned id member out of struct clk since its only
really useful for proc_comm clocks. This means we have to define
all the struct clk's before hand, but we actually want to do this
so we can point voter clocks at the struct clk directly.

Voting clocks are linked to the clock they vote on with a parent
pointer. Add support for these functions so the upcoming clock
voter sub driver can use it to initialize clocks.

The debugfs operations currently sidestep the top level
enable/disable code and directly call the ops->enable/disable
functions. This won't work well when we generically enable parent
clocks in the toplevel clock code. Therefore call enable/disable
directly from the debugfs code to get proper parent enabling.

Enable the parent clocks whenever a clock is enabled and disable
a parent clock whenever a clock is disabled. This simplifies
sub-driver code by centralizing the parent enabling in the
top-level.

Some clocks have multiple consumers where each consumer requires
a minimum rate. Implement a sub driver to aggregate
clk_set_rate() calls from each consumer and call clk_set_rate()
on the parent clock when the minimum requested rate of all the
voters changes.

The pbus clock always runs at half the ebi1 clock frequency.
Since ebi1 clock votes are dropped when the application processor
is power collapsed, the ebi1 clock is reserved for the acpuclock
driver. Other drivers which have ebi1 clock requirements that are
independent of application processor power status use the pbus.
To keep this change transparent across drivers and SoCs, add new
ops that divides the rate by 2 before sending the request to the
modem.

Not all clock drivers want to implement support for all the
clk_*() operations. Since only clk_enable(), clk_disable(), and
clk_set_rate() are mandatory, allow the other clk_*() functions
to be optionally implemented by subdrivers. Also make
clk_enable() and clk_disable() optional so that clocks with no
on/off support don't have to define empty clk_enable/disable ops.

Some clocks are simple enough that determining if they are
enabled or disabled can be done by reading the 'count' member of
struct clk. Implement support for such clocks in clock-debug.c so
that these types of clocks don't need to implement the
is_enabled() ops.

The 7x30 clock driver needs to perform clock resets and the only
way that is possible is through proc_comm. Expose the reset
functionality as a new function callable from the 7x30 clock
driver.

Add debugfs nodes to list all of the supported rates for rate-settable
locally-controlled clocks. This allows a clock's supported rates to
be queried from userspace, and allows more comprehensive userspace
clock tests to be developed.

From: Matt Wagantall <mattw@codeaurora.org>
Use the SoC's ring oscillator hardware to measure the clock rate
of locally-controlled clocks. This allows for the development of
more comprehensive end-to-end clock tests.
A 'measure' debugfs node is created for each clock to perform the
measurement and retrieve the result. soc_clk_measure_rate() should
*only* be used for debug purposes since it busy-loops while the
measurement takes place (~15 ms).
Clock rates are in units of Hz. Clocks that don't support rate
measurement will return -1.

From: Matt Wagantall <mattw@codeaurora.org>
Users of these debug facilities should keep in mind that these
clocks can gate automatically when the CPU or L2 is idle,
resulting in a lower-than-expected or 0 Hz measurement in those
cases.
Also, because the test points used to measure these clocks are
after a hard-wired divide-by-two, the rates of these clocks
are multiplied again by two in software to get the actual CPU
and L2 rates. When observing these clocks on an oscilloscope,
however, the half-rate clocks are what is seen.

Implement a dummy clock driver and macro in the spirit of
CLK_PCOM(). This is useful on targets where a pclk doesn't exist
and we want to keep drivers sane by providing such clocks.

The machine descriptor for FLUID was missing. Adding it allows us
to boot FLUID devices since the basic support for 8660 is the
same.

All locally controlled clocks can participate in the auto off
operations. Make the auto off flag default (and 0) to save lines
in struct clk definitions. We make the auto_off ops optional to
avoid marking PLLs and XOs explicitly.

These were just defined to be the same as CLKFLAG_MIN,
CLKFLAG_MAX and (CLKFLAG_MIN | CLKFLAG_MAX). Expand them
to avoid the unnecessary level of redirection.

From: Matt Wagantall <mattw@codeaurora.org>
The ADM driver wishes to vote for EBI1 clock rates during ADM
transfers. Add voter clocks for this purpose.
On msm8960, this also requires the creation of an EBI voter clock
for the msm_bus driver, since it was previously using the clock
directly.

From: Stephen Boyd <sboyd@codeaurora.org>
Every board file calls msm_clock_init() to initialize the clocks
and msm_clock_init() in turn calls msm_clk_soc_init() to do any
SoC specific initialization. Invert the call order so that boards
that require SoC specific initialization call the SoC specific
function first which then calls the generic msm_clock_init().
This removes one more obstacle in the path of multi-arch kernels
in mach-msm.

Earlier code for MSM uarts had three separate drivers, one for the old
"legacy" hardware, one for the new DMA-based hardware, and a third
that used the DMA-based hardware in a legacy-compatible mode.
The current msm_serial driver handles both the older hardware and the
DMA-based hardware in non-DMA mode from the same driver. Rename the
clocks for this device to support this usage.

The driver explicitly requests a clock rate for the UART, but it is
off by a factor of four from the dividers that it programs into the
UART. Fix this by setting the rate to 1/4 of the current value.
