As per recent discussion on the linux-omap list, we are
moving in the direction where, we will have only architecture,
ARCH_OMAP2PLUS and all devices/platforms will be treated
as a SoC underneath.
So the first step in this direction is to adopt this change
for all new devices getting in, converting
cpu_is_am33xx/335x() ==> soc_is_am33xx/335x()

During kernel init, the AM3505/AM3517 UART4 cannot complete its softreset:
omap_hwmod: uart4: softreset failed (waited 10000 usec)
This also results in another warning later in the boot process:
omap_hwmod: uart4: enabled state can only be entered from initialized, idle, or disabled state
From empirical observation, the AM35xx UART4 IP block requires either
uart1_fck or uart2_fck to be enabled while UART4 resets. Otherwise
the reset will never complete. So this patch adds uart1_fck as an
optional clock for UART4 and adds the appropriate hwmod flag to cause
uart1_fck to be enabled during the reset process. (The choice of
uart1_fck over uart2_fck was arbitrary.)
Unfortunately this observation raises many questions. Is it necessary
for uart1_fck or uart2_fck to be controlled with uart4_fck for the
UART4 to work correctly? What exactly do the AM35xx UART4 clock
tree and the related PRCM idle management FSMs look like? If anyone
has the ability to answer these questions through empirical functional
testing, or hardware information from the AM35xx designers, it would
be greatly appreciated.

Add missing terminators to the arrays of IRQ, DMA, and address space
structure records in the AM35xx UART4 hwmod data. Without these
terminators, the following warnings appear on boot:

Partially fix the hwmod data for the AM35xx USB OTG hwmod. This
should resolve the following boot warning on AM35xx platforms:
omap_hwmod: am35x_otg_hs: cannot be enabled for reset (3)
While here, also fix the clkdev records, to avoid warnings about
duplicate clock aliases.
The hwmod is also connected to the wrong interconnect. It should be
connected to the IPSS, not the L4 CORE. But that is left for a future
fix, since it probably has a dependency on some hwmod core changes.

The OMAP dmtimer driver allows you to dynamically configure the functional
clock that drives the timer logic. The dmtimer driver uses the device name and
a "con-id" string to search for the appropriate functional clock.
Currently, we define a clock alias for each functional clock source each timer
supports. Some functional clock sources are common to all of the timers on a
device and so for these clock sources we can use a single alias with a unique
con-id string.
The possible functional clock sources for an OMAP device are a 32kHz clock,
a system (MHz range) clock and (for OMAP2 only) an external clock. By defining
a unique con-id name for each of these (timer_32k_ck, timer_sys_ck and
timer_ext_ck) we can eliminate a lot of the clock aliases for timers. This
reduces code, speeds-up searches and clock initialisation time.

The init for 3505/3517 specific clocks depends on the ordering of
cpu_is checks, is error prone and confusing (there are 2 separate
checks for cpu_is_omap3505()).
Remove the 3505-specific checking since CK_3505 flag is not used, and
treat all AM35x clocks the same.
This means that the SGX clock (the only AM35x clkdev not currently
flagged for 3505) will now be registered on 3505, but that is
harmless. That can be cleaned up when the clkdev nodes are removed in
favor of them being registered by hwmod.

Commit 2a9f5a4d455 "OMAP3 clock: remove unnecessary duplicate of dpll4_m2_ck,
added for 36xx" consolidated dpll4 clock structures between 34xx and 36xx,
but left 34xx CLKSEL masks for most dpll4 related clocks, which causes
clock code to not behave correctly when booting on DM3730 with higher
(36xx only) divisors set:
[ 0.000000] WARNING: at arch/arm/mach-omap2/clkt_clksel.c:375 omap2_init_clksel_parent+0x104/0x114()

[ 0.000000] clock: Could not find fieldval 0 for clock dpll4_m3_ck parent dpll4_ck
Fix this by switching to 36xx masks, as valid divisors will be limited
by clksel_rate lists.

Several platforms create IOMEM defines for casting to 'void __iomem *',
and other platforms are incorrectly using __io() macro for the same
purpose. This creates a common definition and removes all the platform
specific versions. Rather than try to make linux/io.h and asm/io.h
assembly safe, the assembly version of IOMEM is moved into
asm/assembler.h.

The oscillator that supplies GPT12_FCLK and WDT1_FCLK exists in the
WKUP powerdomain[1]. This resolves at least one boot-time warning:
omap_hwmod: gpt12_fck: missing clockdomain for gpt12_fck.

Extend the existing function to create clkdev for every optional
clocks to add a well one "fck" alias for the main_clk of the
omap_hwmod.
It will allow to remove these static clkdev entries from the
clockXXX_data.c file.

Currently, clock database has <dev, clock-name> tuples for DSS2. Because of
this, the clock names are different across different OMAP platforms.
This patch aligns the DSS2 clock names and roles across OMAP 2420, 2430, 3xxx,
44xx platforms in the clock databases, hwmod databases for opt-clocks, and DSS
clock handling.
This ensures that clk_get/put/enable/disable APIs in DSS can use uniform role
names.

All clock management is moved to dss platform driver. clk_get/put APIs use
dss device instead of core platform device.
Hwmod adaptation design requires each of the DSS HW IP to be a platform driver.
So the device name is changed from omapdss to omapdss_dss in 2420, 2430,
3xxx clock database files. Now the core driver "omapdss" only takes care
of panel registration with the custom bus.
core driver also uses the clk_enable() / clk_disable() APIs exposed by DSS for
clock management.
DSS driver would do clock management of clocks needed by DISPC, RFBI, DSI, VENC
TODO: The clock content would be adapted to omap_hwmod in a seperate series.

Remove the DPLL rate tolerance code that is called during rate
rounding. As far as I know, this code is never used, since it's been
more important for callers of the DPLL round_rate()/set_rate()
functions to obtain an exact rate than it is to save a relatively
small amount of power.

Mark each interface clock with a corresponding CM_AUTOIDLE bit with
a clkops that has the allow_idle/deny_idle function pointers populated.
This allows the OMAP clock framework to enable and disable autoidle for
these clocks.

The devices of clocks are set to usbhs, so that
only usbhs common driver can invoke these clocks.
The dummy per port clocks are added to omap3
clock data base. This helps to invoke common
clock get APIs for omap3 and omap4.

Disable autoidle on all clocks during clock framework initialization.
(If CONFIG_PM is set, autoidle is re-enabled for all clocks later in
the boot process.)
The principle behind this patch, and some similar patches, is that the
kernel should start with all power management features disabled.
Later in the boot process, the PM code, if compiled in with CONFIG_PM,
enables or re-enables power management features.

DPLL1 on omap3 is very similar to the rest of
the non-core dpll's.
Hence populate clkops_omap3_noncore_dpll_ops
as the clkops for it, instead of the
currently populated clkops_null.
