This is the bulk of new SoC enablement and other platform changes for 3.17:
* Samsung S5PV210 has been converted to DT and multiplatform
* Clock drivers and bindings for some of the lower-end i.MX 1/2 platforms
* Kirkwood, one of the popular Marvell platforms, is folded into the
mvebu platform code, removing mach-kirkwood.
* Hwmod data for TI AM43xx and DRA7 platforms.
* More additions of Renesas shmobile platform support
* Removal of plat-samsung contents that can be removed with S5PV210 being
multiplatform/DT-enabled and the other two old platforms being removed.
New platforms (most with only basic support right now):
* Hisilicon X5HD2 settop box chipset is introduced
* Mediatek MT6589 (mobile chipset) is introduced
* Broadcom BCM7xxx settop box chipset is introduced
+ as usual a lot other pieces all over the platform code.

Without this, the USB devices are sometimes not detected on OMAP4 Panda
with u-boot v2013.10.
Unlike what the comment states, errata i660 does not state that we
can't RESET the USB host module. Instead it states that RESET is the
only way to recover from a deadlock situation.
RESET ensures that the module is in a known good state irrespective
of what bootloader does with the module, so it must be done at boot.

With commit '82702ea11ddfe0e43382e1fa5b66d807d8114916' "ARM: OMAP2+:
Fix serial init for device tree based booting" stubbing out
omap_serial_early_init() for Device tree based booting, there was a
crash observed on AM335x based devices when hwmod does a
_setup_reset() early at boot.
This was rootcaused to hwmod trying to reset console uart while
earlycon was using it. The way to tell hwmod not to do this is to
specify the HWMOD_INIT_NO_RESET flag, which were infact set by the
omap_serial_early_init() function by parsing the cmdline to identify
the console device.
Parsing the cmdline to identify the uart used by earlycon itself seems
broken as there is nothing preventing earlycon to use a different one.
This patch, instead, attempts to populate the requiste flags for hwmod
based on the CONFIG_DEBUG_OMAPxUARTy FLAGS. This gets rid of the need
for cmdline parsing in the DT as well as non-DT cases to identify the
uart used by earlycon.

retained since MMC, NFS boot was not working. Since it is root caused
to be an issue with only DMA entries [1], irq can be safely removed.

Commit 3b9b10151c (ARM: OMAP4: hwmod data:

- The IO resource information like dma request lines, irq number and
ocp address space can be populated via dt blob. So such data is stripped
from OMAP4 SOC hwmod data file.
- The devices which are still missing the device tree bindings,
address space entries are not removed yet. When such devices add
the dt bindings, respective address space data can be deleted.
- Also other unnecessary hwmods like firewalls are removed as a part of this.
Since emif was getting registered only because of this firewalls links,
the mpu->emif direct link is added now.
The above update, results in reduction of about ~1650 lines of code.

OMAP UART IP needs software control for slave idle modes based on functional
state of the IP. i.e The IP slave idle settings should be set to 'noidle' when
being used and then put back to 'smart_idle' when unused. Currently this is
handled by the driver with function pointers implemented in platform code.
This however breaks in case of device tree because of missing idle handling
APIs.
Previous patches in this series added a flag HWMOD_SWSUP_SIDLE_ACTIVE which
takes care of the mentioned requirement. Hence add the flag for all UART IPs
to take advantage of feature supported by framework.
Subsequent patches removes the slave idle handling from driver code.

Commit 17b7e7d335 ("ARM: OMAP4:
clock/hwmod data: start to remove some IP block control "clocks"")
introduced a regression preventing the L3INIT clockdomain of OMAP4
systems from entering idle. This in turn prevented these systems from
entering full chip clock-stop.
The regression was caused by the incorrect removal of a so-called
"optional functional clock" from the OMAP4 clock data. This wasn't
caught for two reasons. First, I missed the retention entry failure
in the branch test logs:
http://www.pwsan.com/omap/testlogs/cleanup_a_3.9/20130126014242/pm/4460pandaes/4460pandaes_log.txt
Second, the integration data for the OCP2SCP PHY IP block, added by
commit 0c6688753f ("ARM: OMAP4: hwmod
data: add remaining USB-related IP blocks"), should have associated this
clock with the IP block, but did not.
Fix by adding back the so-called "optional" functional clock to the
clock data, and by linking that clock to the OCP2SCP PHY IP block
integration hwmod data.

Add AESS memory bank data in hwmod in order to provide memory address
information to the driver.
This version also changes the AESS main clock to use a
non-CLKCTRL-based functional clock. These are being removed from the
clock data, since they should be handled by the IP block integration
code. Without this change, the kernel crashes during boot. Thanks to
Tony Lindgren for reporting this during a test merge.

Enable the AESS auto-gating control bit during AESS hwmod setup. This
fixes the following boot warning on OMAP4:
omap_hwmod: aess: _wait_target_disable failed
Without this patch, the AESS IP block does not indicate to the PRCM
that it is idle after it is reset. This prevents some types of SoC
power management until something sets the auto-gating control bit.

Convert all DEFINE_OMAP_MUX_GATE() combinations that list MODULEMODE
registers in their gate arguments to DEFINE_OMAP_MUX(), dropping the
MODULEMODE data. This is possible because the MODULEMODE bits control
IP blocks, not clocks; and the hwmod code takes care of IP block
control. Rename these clocks to reflect the original multiplexer name
as specified in the comments. And convert the hwmod data to use the
multiplexer clock name.

Remove some leaf "clocks" that are actually IP block idle control
points, since these should now be handled by the hwmod code.
There are still a few types of MODULEMODE clocks that need to be
cleaned up:
- those still in use by driver or integration code
- those in DEFINE_CLK_OMAP_MUX_GATE() blocks; the gate portion of
these should be removed
A similar process may also be possible on OMAP2/3.

Here are few more patches to finish the omap changes for
multiplatform conversion that are not strictly fixes, but
were too complex to do with the dependencies during the

platform_data, and the removal of remaining cpu_is_omap
macro usage outside mach-omap2.
Then there are several trivial fixes for typos and few

dma_mapping_error by the device driver. This requires minor changes to
some architectures which make use of dma-debug. Most of these changes
have the respective Acks by the Arch-Maintainers.

Signed-off-by: Olof Johansson <olof@lixom.net>
Based on earlier discussions[1] we attempted to find a suitable
location for the omap DMA header in commit 2b6c4e73 (ARM: OMAP:
DMA: Move plat/dma.h to plat-omap/dma-omap.h) until the conversion
to dmaengine is complete.
Unfortunately that was before I was able to try to test compile
of the ARM multiplatform builds for omap2+, and the end result
was not very good.
So I'm creating yet another all over the place patch to cut the
last dependency for building omap2+ for ARM multiplatform. After
this, we have finally removed the driver dependencies to the
arch/arm code, except for few drivers that are being worked on.
The other option was to make the <plat-omap/dma-omap.h> path
to work, but we'd have to add some new header directory to for
multiplatform builds.
Or we would have to manually include arch/arm/plat-omap/include
again from arch/arm/Makefile for omap2+.
Neither of these alternatives sound appealing as they will
likely lead addition of various other headers exposed to the
drivers, which we want to avoid for the multiplatform kernels.
Since we already have a minimal include/linux/omap-dma.h,
let's just use that instead and add a note to it to not
use the custom omap DMA functions any longer where possible.
Note that converting omap DMA to dmaengine depends on
dmaengine supporting automatically incrementing the FIFO
address at the device end, and converting all the remaining
legacy drivers. So it's going to be few more merge windows.

Currently OMAP2+ devices are using the function __omap_dm_timer_reset() to
configure the clock-activity, idle, wakeup-enable and auto-idle fields in the
timer OCP_CFG register. The name of the function is mis-leading because this
function does not actually perform a reset of the timer.
For OMAP2+ devices, HWMOD is responsible for reseting and configuring the
timer OCP_CFG register. Therefore, do not use __omap_dm_timer_reset() for
OMAP2+ devices and rely on HWMOD. Furthermore, some timer instances do not
have the fields clock-activity, wakeup-enable and auto-idle and so this
function could configure the OCP_CFG register incorrectly.
Currently HWMOD is not configuring the clock-activity field in the OCP_CFG
register for timers that have this field. Commit 0f0d080 (ARM: OMAP: DMTimer:
Use posted mode) configures the clock-activity field to keep the f-clk enabled
so that the wake-up capability is enabled. Therefore, add the appropriate flags
to the timer HWMOD structures to configure this field in the same way.
For OMAP2/3 devices all dmtimers have the clock-activity field, where as for
OMAP4 devices, only dmtimer 1, 2 and 10 have the clock-activity field.
Verified on OMAP2420 H4, OMAP3430 Beagle and OMAP4430 Panda that HWMOD is
configuring the dmtimer OCP_CFG register as expected for clock-events timer.

Most of the prototypes in plat-omap/common.h are not
common to omap1 and omap2+, they are local to omap2+
and should not be in plat-omap/common.h.
The only shared function prototype in this file is
omap_init_clocksource_32k(), let's put that into
counter-32k.h.
Note that the new plat/counter-32k.h must not be
included from drivers, that will break omap2+ build
for CONFIG_MULTIPLATFORM.

Resolve this kernel boot message:
omap_hwmod: mcpdm: cannot be enabled for reset (3)
The McPDM on OMAP4 can only receive its functional clock from an
off-chip source. This source is not guaranteed to be present on the
board, and when present, it is controlled by I2C. This would
introduce a board dependency to the early hwmod code which it was not
designed to handle. Also, neither the driver for this off-chip clock
provider nor the I2C code is available early in boot when the hwmod
code is attempting to enable and reset IP blocks. This effectively
makes it impossible to enable and reset this device during hwmod init.
At its core, this patch is a workaround for an OMAP hardware problem.
It should be possible to configure the OMAP to provide any IP block's
functional clock from an on-chip source. (This is true for almost
every IP block on the chip. As far as I know, McPDM is the only
exception.) If the kernel cannot reset and configure IP blocks, it
cannot guarantee a sane SoC state. Relying on an optional off-chip
clock also creates a board dependency which is beyond the scope of the
early hwmod code.
This patch works around the issue by marking the McPDM hwmod record
with the HWMOD_EXT_OPT_MAIN_CLK flag. This prevents the hwmod
code from touching the device early during boot.

There's no need to keep the device related things in the
common i2c.c as omap2+ is using hwmod. Split the code to
mach-omap1 and mach-omap2 parts and only leave common
code to plat-omap/i2c.c.
Note that as omap1 only has one i2c controller, we can
now remove the old device related macros.
