e53a11bef5 arm: allwinner: Set aw_ccu to BUS_PASS_BUS
In r350842 I've switched the bus pass to resource so it matches the other
clock drivers but this cannot work as this drivers is meant to match
the dts node '/clocks' and if we don't do it at this pass simplebus is
catching this node and we cannot attach.
This solve booting on Allwinner boards that are still using /clocks (A20 SoC)

d27bec74fe allwinner: Add support to min/max in aw_clk_frac
The Fractionals clock in Allwinner device have some min/max frequencies

8c8b86922a allwinner: Add a new clock aw_clk_m
We used the aw_clk_nm clock for clock with only one divider factor
and used a fake multiplier factor. This cannot work properly as we
end up writing the "fake" factor to the register (and so always set
the LSB to 1).
Create a new clock for those.
The reason for not using the clk_div clock is because those clocks are
a bit special. Since they are (almost) all related to video we also need
to set the parent clock (the main PLL) to a frequency that they can support.
As the main PLL have some minimal frequency that they can support we need to
be able to set the main PLL to a multiple of the desired frequency.
Let say you want to have a 71Mhz pixel clock (typical for a 1280x800 display)
and the main PLL cannot go under 192Mhz, you need to set it to 3 times the
desired frequency and set the divider to 3 on the hdmi clock.
So this also introduce the CLK_SET_ROUND_MULTIPLE flag that allow for this kind
of scenario.

cfc8861b06 allwinner: Rework the BUS_PASS on drivers
- Put all clock and control unit driver in BUS_PASS_RESOURCE except
  for the DE2 CCU as it needs the main CCU to be available.
- Use BUS_PASS_CPU for a20_cpu_cfg as it makes more sense.
- For aw_syscon use SCHEDULER pass as we need it early for drivers
  that attach in BUS_PASS_SUPPORTDEV
- For the rest we can use BUS_PASS_SUPPORTDEV

b93539730b Rename pwmbus.h to ofw_pwm.h, because after all the recent changes, there
is nothing left in the file that related to pwmbus at all.  It just contains
prototypes for the functions implemented in dev/pwm.ofw_pwm.c, so name it
accordingly and fix the include protect wrappers to match.

A new pwmbus.h will be coming along in a future commit.

f8f8d87cd9 Restructure the pwm device hirearchy and interfaces.
The pwm and pwmbus interfaces were nearly identical, this merges them into a
single pwmbus interface.  The pwmbus driver now implements the pwmbus
interface by simply passing all calls through to its parent (the hardware
driver).  The channel_count method moves from pwm to pwmbus, and the
get_bus method is deleted (just no longer needed).

The net effect is that the interface for doing pwm stuff is now the same
regardless of whether you're a child of pwmbus, or some random driver
elsewhere in the hierarchy that is bypassing the pwmbus layer and is talking
directly to the hardware driver via cross-hierarchy connections established
using fdt data.

The pwmc driver is now a child of pwmbus, instead of being its sibling
(that's why the get_bus method is no longer needed; pwmc now gets the
device_t of the bus using device_get_parent()).

1bf4afc527 Don't call pwmbus_attach_bus(), because it may not be present if this
driver is compiled into the kernel but pwmbus will be loaded as a module
when needed (and because of that, pwmbus_attach_bus() is going away in
the near future).  Instead, just directly do what that function did:
register the fdt xfef handle, and attach the pwmbus.

5ef9c1079e In detach(), check for failure of bus_generic_detach(), only release
resources if they got allocated (because detach() gets called from attach()
to handle various failures), and delete the pwmbus child if it got created.

e12be3218a Include eventhandler.h in more compilation units
This was enumerated with exhaustive search for sys/eventhandler.h includes,
cross-referenced against EVENTHANDLER_* usage with the comm(1) utility.  Manual
checking was performed to avoid redundant includes in some drivers where a
common os_bsd.h (for example) included sys/eventhandler.h indirectly, but it is
possible some of these are redundant with driver-specific headers in ways I
didn't notice.

(These CUs did not show up as missing eventhandler.h in tinderbox.)

e2e050c8ef Extract eventfilter declarations to sys/_eventfilter.h
This allows replacing "sys/eventfilter.h" includes with "sys/_eventfilter.h"
in other header files (e.g., sys/{bus,conf,cpu}.h) and reduces header
pollution substantially.

EVENTHANDLER_DECLARE and EVENTHANDLER_LIST_DECLAREs were moved out of .c
files into appropriate headers (e.g., sys/proc.h, powernv/opal.h).

As a side effect of reduced header pollution, many .c files and headers no
longer contain needed definitions.  The remainder of the patch addresses
adding appropriate includes to fix those files.

LOCK_DEBUG and LOCK_FILE_LINE_ARG are moved to sys/_lock.h, as required by
sys/mutex.h since r326106 (but silently protected by header pollution prior
to this change).

No functional change (intended).  Of course, any out of tree modules that
relied on header pollution for sys/eventhandler.h, sys/lock.h, or
sys/mutex.h inclusion need to be fixed.  __FreeBSD_version has been bumped.

bfcf888a87 arm: allwinner: Fix audio for Allwinner H3/H5
Due to three conditions the codec driver for Allwinner A10/A20 and H3/H5 did not work properly here:

    Wrong bit position for the analog audio reset
    Hardware Reset of codec was not de-asserted correctly
    Linux DTS file did not contain the address of the analog register the way as the driver was expecting it.

This patch proposes fixes for those three parts.

5f50cbd3de aw_rtc: Register the clocks
Since latest DTS update the rtc is supposed to register two clocks :

- osc32k (the 32k oscillator on the board that the RTC uses directly and
that other peripheral can use)
- iosc (the internal oscillator of the RTC when available which frequency
depend on the SoC revision)

Since we need the RTC before the proper clock control unit (because it uses
those clocks) attach it a BUS_PASS_BUS + MIDDLE and attach the clock control
unit at BUS_PASS_BUS + LAST for the SoC that requires it.
