ARM: OMAP2+: am33xx: Make am33xx as a separate class
Initially, we decided to make am33xx family of device to fall
under omap3 class (cpu_is_omap34xx() = true), since it carries
Cortex-A8 core. But while adding complete baseport support
(like, clock, power and hwmod) support, it is observed that,
we are creating more and more problems by treating am33xx device
as omap3 family, as nothing matches between them
(except cortex-A8 mpu).
So, after long discussion we have came to the conclusion that,
we should not consider am33xx device as omap3 family, instead
create separate class (SOC_AM33XX) under OMAP2PLUS.
This means, for am33xx device, cpu_is_omap34xx() will return false,
and only cpu_is_am33xx() will be true.

3. 32KHz based gptimer.
The optional gptimer based clocksource was added so that it can
give the high precision than sync-timer, so expected usage was 2
and not 3.
Unfortunately option 2, clocksource doesn't meet the requirement of
free-running clock as per clocksource need. It stops in low power states
when sys_clock is cut. That makes gptimer based clocksource option
useless for OMAP2/3/4 devices with sys_clock as a clock input.
So, in order to use option 2, deeper idle state MUST be disabled.
Option 3 will still work but it is no better than 32K sync-timer
based clocksource.
We must support both sync timer and gptimer based clocksource as
some OMAP based derivative SoCs like AM33XX does not have the
sync timer.
Considering above, make sync-timer and gptimer clocksource runtime
selectable so that both OMAP and AMXXXX continue to use the same code.
And, in order to precisely configure/setup sched_clock for given
clocksource, decision has to be made early enough in boot sequence.
So, the solution is,
Use standard kernel parameter ("clocksource=") to override
default 32k_sync-timer, in addition to this, we also use hwmod database
lookup mechanism, through which at run-time we can identify availability
of 32k-sync timer on the device, else fall back to gptimer.
Also, moved low-level SoC specific init code to respective files,
(mach-omap1/timer32k.c and mach-omap2/timer.c)

Depending on the bootloader, passing command-line arguments

to pass along the quotes, passing only 'gp' part of the string,
which leads to wrong override configuration.
The only affected kernel parameter configuration for OMAP family

So this patch changes "gp timer" => "gp_timer", for clockevent,

ARM: OMAP2+: WDTIMER integration: fix !PM boot crash, disarm timer after hwmod reset
Without runtime PM enabled, hwmod needs to leave all IP blocks in an
enabled state by default so any driver access to the HW will succeed.
This is accomplished by seting the postsetup_state to enabled for all
hwmods during init when runtime PM is disabled.
Currently, we have a special case for WDT in that its postsetup_state
is always set to disabled. This is done so that the WDT is disabled
and the timer is disarmed at boot in case there is no WDT driver.
This also means that when runtime PM is disabled, if a WDT driver *is*
built in the kernel, the kernel will crash on the first access to the
WDT hardware.
We can't simply leave the WDT module enabled, because the timer is
armed by default after reset. That means that if there is no WDT
driver initialzed or loaded before the timer expires, the kernel will
reboot.
To fix this, a custom reset method is added to the watchdog class of
omap_hwmod. This method will *always* disarm the timer after hwmod
reset. The WDT timer then will only be rearmed when/if the driver is
loaded for the WDT. With the timer disarmed by default, we no longer
need a special-case for the postsetup_state of WDT during init, so it
is removed.
Any platforms wishing to ensure the watchdog remains armed across the
entire boot boot can simply disable the reset-on-init feature of the
watchdog hwmod using omap_hwmod_no_setup_reset().
Tested on 3530/Overo, 4430/Panda.
NOTE: on 4430, the hwmod OCP reset does not seem to rearm the timer as
documented in the TRM (and what happens on OMAP3.) I noticed this
because testing the HWMOD_INIT_NO_RESET feature with no driver loaded,
I expected a reboot part way through the boot, but did not see a
reboot. Adding some debug to read the counter, I verified that right
after OCP softreset, the counter is not firing. After writing the
magic start sequence, the timer starts counting. This means that the
timer disarm sequence added here does not seem to be needed for 4430,
but is technically the correct way to ensure the timer is disarmed, so
it is left in for OMAP4.
Special thanks to Paul Walmsley for helping brainstorm ideas to fix
this problem.

users of it with pwrdm_state_switch()

ARM: OMAP3+: dpll: Configure autoidle mode only if it's supported
The current DPLL code enables and disables autoidle features
without checking whether the autoidle register is available.
Fix this by putting a check for the existence of the autoidle
register in the DPLL data.
With such a check in place, for DPLLs which do not support this
feature, simply skipping the autoidle_reg entry in the DPLL data
is sufficient.

ARM: OMAP4+: Add prm and cm base init function.
Instead of statically defining seperate arrays for every OMAP4+ archs,
have a generic init function to populate the arrays. This avoids the
need for creating new array for every arch added in the future that
reuses the prm and cm registers read/write code.

ARM: OMAP3: clock data: treat all AM35x devices the same
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.
