The OMAP iommu driver performs the reset management for the
iommu instances in processor sub-systems using the omap_device
API which are currently supplied as platform data ops. Use pdata
quirks to maintain the functionality as the OMAP iommu driver
gets converted to use DT nodes, until the reset portions are
decoupled from omap_hwmod/omap_device into a separate reset
driver.
This patch adds the pdata quirks for the reset management of
iommus within the DSP (OMAP3 & OMAP4) and IPU subsystems (OMAP4).

The IOMMU DT adaptation support uses the device name instead
of an iommu object name. Fixup the ISP device archdata MMU
name at runtime if using DT-boot. This allows the OMAP3 camera
to be functional in both legacy and DT boots. The iommu object
names should eventually vanish when all the IOMMU users have
been converted to DT nodes.

The IVA MMU is not functional when used through the hwmod and
omap_device layers. Add fixes to clockdomain and hwmod data
to have it functional. The hwmod changes are needed to enable
the clock, and the SWSUP change is needed to wakeup the domain
because the power domain is programmed to be in RET, and there
is no automatic power domain switching to ON.

CONFIG_OMAP_IOMMU_IVA2 was defined originally to avoid conflicting
usage by tidspbridge and other iommu users. The same can be achieved
by marking the DT node disabled, so remove this obsolete flag and
the corresponding hwmod data can be enabled.

1) An inaccuarte 32k clock (CLK_32KHZ) derived from PER DPLL, causing system

2) external 32KHz RTC clock, which may not always be available on board like

Since commit 65aa94b204 (ARM: OMAP4: clockdomain/CM code: Update supported
transition modes), on OMAP4, all CLKDMs support HW_AUTO so this is used
instead of SW_SLEEP for the idling of clockdomains. However, additional
SoCs now leverage the OMAP4 clockdomain code so update it to use SW_SLEEP
if the clockdomain data specifies that the CLKDM has the
CLKDM_CAN_FORCE_SLEEP flag set rather than using HW_AUTO for both cases.
Without this patch, clockdomain handling is broken on AM43xx and no
clockdomains are actually being put into idle on this platform. Any
attempt to idle them results in the HW_AUTO value (0x3) being written
to them with no apparent effect.

thumb mode. Also few other regressions and fixes.

After splitting padconf core into two parts to avoid exposing
unaccessable registers, the new padconf core2 domain was left
without a wake-up interrupt.
Fix the issue by passing the shared wake-up interrupt in
platform data like we do for padconf core and wkup domains
already.

If CLK_SET_RATE_PARENT is set for a clkoutx2 clock, calling
clk_set_rate() on the clock "skips" the x2 multiplier as there are no
set_rate and round_rate functions defined for the clkoutx2.
This results in getting double the requested clock rates, breaking the
display on omap3430 based devices. This got broken when
d0f58bd3bb and related patches were merged
for v3.14, as omapdss driver now relies more on the clk-framework and
CLK_SET_RATE_PARENT.
This patch implements set_rate and round_rate for clkoutx2.
Tested on OMAP3430, OMAP3630, OMAP4460.
