0ef64986d6 ARM: omap: dma: get rid of errata global
There's no need for this to be a global variable; move it into the
errata configuration function instead.

b9f2b21a32 Devicetree changes for v3.15
Updates to devicetree core code. This branch contains the following notable changes:
 * Add reserved memory binding
 * Make struct device_node a kobject and remove legacy /proc/device-tree
 * ePAPR conformance fixes
 * Update in-kernel DTC copy to version v1.4.0
 * Preparation changes for dynamic device tree overlays
 * minor bug fixes and documentation changes
 
 The most significant change in this branch is the conversion of struct
 device_node to be a kobject that is exposed via sysfs and removal of the
 old /proc/device-tree code. This simplifies the device tree handling
 code and tightens up the lifecycle on device tree nodes.

6a0e6b3872 ARM: OMAP2+: DT 'compatible' tweak for displays
As there is no common panel framework in the kernel, we have OMAP
specific panel drivers. However, the DT data should be generic. This
brings the issue that some other platform could use the same panels, and
would need to create a driver with the same 'compatible' string as the
OMAP driver.

In the long run, we have to get a common panel framework. For the time
being, this patch solves the issue:

At early boot time, we go through the DT nodes looking for the panels
the kernel supports for OMAP. For each found node, the 'compatible'
string is prepended with "omapdss,", i.e. "sony,acx565akm" becomes
"omapdss,sony,acx565akm". The OMAP display drivers all have "omapdss,"
at the beginning of their compatible field.

This allows us to have generic DT data, but OMAP specific display
drivers.

dcdf407b9d ARM: OMAP2+: add omapdss_init_of()
The OMAP display architecture requires a bunch of platform devices which
are not created via .dts (for now). We also need to pass a few function
pointers and the DSS hardware version from the arch code to omapdss
driver.

This patch adds omapdss_init_of() function, called from board-generic at
init time, which handles those tasks.

698b485325 ARM: OMAP2+: INTC: Acknowledge stuck active interrupts
When an interrupt has become active on the INTC it will stay active
until it is acked, even if masked or de-asserted. The
INTC_PENDING_IRQn registers are however updated and since these are
used by omap_intc_handle_irq to determine which interrupt to handle,
it will never see the active interrupt. This will result in a storm of
useless interrupts that is only stopped when another higher priority
interrupt is asserted.

Fix by sending the INTC an acknowledge if we find no interrupts to
handle.

910f1678bb ARM: OMAP2+: use pdata quirks for iommu reset lines
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).

0ac4f03f62 ARM: OMAP2+: change the ISP device archdata MMU name for DT
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.

200a274f35 ARM: OMAP3: fix iva mmu programming issues
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.

895a9613a1 ARM: OMAP3: remove deprecated CONFIG_OMAP_IOMMU_IVA2
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.

5b5c013591 ARM: OMAP2+: AM43x: Use gptimer as clocksource
The SyncTimer in AM43x is clocked using the following two sources:
1) An inaccuarte 32k clock (CLK_32KHZ) derived from PER DPLL, causing system
   time to go slowly (~10% deviation).
2) external 32KHz RTC clock, which may not always be available on board like
   in the case of ePOS EVM

Use gptimer as clocksource instead, as is done in the case of AM335x
(which does not have a SyncTimer). With this, system time keeping works
accurately.

b62d91e5e1 ARM: OMAP2+: make reset pulse for sbc-t3x usb hubs
sbc-t3x boards features two external USB ports on SB-T35 baseboard.
The baseboardi USB hub reset signal should be de-asserted to make
those ports functional.

sbc-t3517 features additional (assembled on CoM) USB hub which also
requires reset signal handling.

Add quirks code to handle proper reset pulse signal.
