The way that we detect which OMAP3 chips support I/O wakeup and
software I/O chain clock control is broken.
Currently, I/O wakeup is marked as present for all OMAP3 SoCs other
than the AM3505/3517. The TI81xx family of SoCs are at present
considered to be OMAP3 SoCs, but don't support I/O wakeup. To resolve
this, convert the existing blacklist approach to an explicit,
whitelist support, in which only SoCs which are known to support I/O
wakeup are listed. (At present, this only includes OMAP34xx,
OMAP3503, OMAP3515, OMAP3525, OMAP3530, and OMAP36xx.)
Also, the current code incorrectly detects the presence of a
software-controllable I/O chain clock on several chips that don't
support it. This results in writes to reserved bitfields, unnecessary
delays, and console messages on kernels running on those chips:
http://www.spinics.net/lists/linux-omap/msg58735.html
Convert this test to a feature test with a chip-by-chip whitelist.

An API which translates a standard hwmod name to corresponding
platform_device is useful for drivers when they need to look up the
device associated with a hwmod name to map back into the device
structure pointers. These ideally should be used by drivers in
mach directory. Using a generic hwmod name like "gpu" instead of
the actual device name which could change in the future, allows
us to:
a) Could in effect help replace apis such as omap2_get_mpuss_device,
omap2_get_iva_device, omap2_get_l3_device, omap4_get_dsp_device,
etc..
b) Scale to more devices rather than be restricted to named functions
c) Simplify driver's platform_data from passing additional fields
all doing the same thing with different function pointer names
just for accessing a different device name.

This generalizes the omap2_mcbsp1_mux_clkr_src and omap2_mcbsp1_mux_fsr_src
implementation between generic McBSP and OMAP2 specific McBSP code. These
functions are used to select source for CLKR and FSR signals on OMAP2+.
Start generalizing the code by implementing an optional mux_signal function
pointer in platform data that will implement the actual muxing and which is
called now from omap2_mcbsp1_mux_clkr_src and omap2_mcbsp1_mux_fsr_src.
These functions are to be removed later and cleanup the API so that
mux_signal gets its arguments directly from client code.

This generalizes the omap2_mcbsp_set_clks_src implementation between generic

Implement generalization by having an optional set_clk_src function pointer

pass higher level source clock name (later coming from client driver) that
platform specific code will map to platform specific clock name.
API cleanup between McBSP and client code comes later.

Active sidetone requires that McBSP interface clock doesn't idle and there
is no mechanism in hwmod to turn autoidling on/off in runtime. McBSP2 and 3
in OMAP34xx share their interface clock with McBSP sidetone module and
that interface clock must be active when the sidetone is operating.
Sidetone has its own autoidle bit which should keep the interface clock
active but it is broken. Putting the McBSP core to no-idle mode when the
sidetone is active is no good either since it results to higher power
consumption when using the threshold based DMA transfers.
For making the McBSP code more generic, move this sidetone clock management
with fixme comments to mach-omap2/mcbsp.c and pass pointer to it via
platform data.

In the omap_device PM domain callbacks, use omap_device idle/enable to
automatically manage device idle states during system suspend/resume.
If an omap_device has not already been runtime suspended, the
->suspend_noirq() method of the PM domain will use omap_device_idle()
to idle the HW after calling the driver's ->runtime_suspend()
callback. Similarily, upon resume, if the device was suspended during
->suspend_noirq(), the ->resume_noirq() method of the PM domain will
use omap_device_enable() to enable the HW and then call the driver's
->runtime_resume() callback.
If a device has already been runtime suspended, the noirq methods of
the PM domain leave the device runtime suspended by default.
However, if a driver needs to runtime resume a device during suspend
(for example, to change its wakeup settings), it may do so using
pm_runtime_get* in it's ->suspend() callback.

Add a new field to provide the mode supported by the module.
The mode will control the way mandatory clocks are managed by the PRCM.
0 : Module is temporarily disabled by SW. OCP access to module are stalled.
Can be used to change timing parameter of GPMC module.
1 : Module is managed automatically by HW according to clock domain
transition. A clock domain sleep transition put module into idle.
A wakeup domain transition put it back into function.
If CLKTRCTRL=3, any OCP access to module is always granted.
Module clocks may be gated according to the clock domain state.
2 : Module is explicitly enabled. Interface clock (if not used for
functions) may be gated according to the clock domain state.
Functional clocks are guarantied to stay present. As long as
in this configuration, power domain sleep transition cannot happen.
Some modules will have a modulemode initialized at 1 (HWCTRL) by default.
This is the case for interconnect and simple module like GPIO, WDT, MAILBOX.

In OMAP PRCM terminology, the clock domain is defined as a group of IPs
that share some clocks and most of the time an interface clock.
Every IP does belong to a clockdomain.
For the moment the clock domain attribute is affected to a clock node.
The issue with that approach, is that a clock might or not belong to a
clock domain. Moreover during module transition, it is up to a module
to handle properly the clock domain state and not to a clock node.
Create a clkdm_name attribute to provide this information per hwmod.
Populate this attribute for every OMAP4 hwmod entries.
Future cleanup series with remove that information from the OMAP4 clock
when it is relevant.

The sequence of _ocp_softreset doesn't work for i2c. The i2c module has a
special sequence to reset the module. The sequence is
- Disable the I2C.
- Write to SOFTRESET bit.
- Enable the I2C.
- Poll on the RESETDONE bit.
The sequence is implemented as a function and the i2c_class is updated with
the correct 'reset' pointer. omap_hwmod_softreset function is implemented
which triggers the softreset by writing into sysconfig register. On following
this sequence, i2c module resets properly and timeouts are not seen.

As part of removing cpu_...() from the OMAP I2C driver, we need to
convert the CPU tests into functionality flags that are set by
hwmod class in the same way the IP revision is.
More flags are needed than will fit in the existing u8 flags
member of omap_i2c_dev_attr.
These flags can refer to options inside the IP block but they are
most needed for information about cpu implementation specific
options that are not part of the IP block itself. For example,
how the CPU data bus is wired to the IP block databus differs
between OMAP cpus and affects how you must shift the address in
the IP block, but is not a feature of the IP block itself.

This also corrects an issue where some boards are trying to pass NAND

Finally, .dev_ready is treated as a flag by the driver, so make it bool

This allows us to remove cpu_is_omap calls from init_irq functions.
There should not be any need for cpu_is_omap calls as at this point.
During the timer init we only care about SoC generation, and not about
subrevisions.
The main reason for the patch is that we want to initialize only
minimal omap specific code from the init_early call.

"omap: iovmm: don't check 'da' to set IOVMF_DA_FIXED flag",
changes iovmm to receive flags specified by user, however
the upper 16 bits of the flags are wiped by iovmm itself.
This fixes IOVMF_DA_FIXED flags from being lost, and lets the user

The set_vpp() method provided by physmap passes a map_info back to
the platform code, which has little relevance as far as the platform
is concerned (this parameter is completely unused).
Instead, pass the platform_device, which can be used in the pismo
driver to retrieve some important information in a nicer way, instead
of the hack that was in place.
The empty set_vpp function in board-at572d940hf_ek.c is left untouched,
as the board/SoC is scheduled for removal.

To be able to relocate the .bss section at run time independently from
the rest of the code, we must make sure that no GOTOFF relocations are
used with .bss symbols. This usually means that no global variables can
be marked static unless they're also const.
Let's remove the static qualifier from current offenders, or turn them

Header files in arch/arm/*/include/mach included from
arch/arm/include/asm/*.h are there to provide necessary definitions for
either the rest of the kernel or the ARM specific parts. They shouldn't
be polluted with *any* platform private stuff which is not absolutely
necessary to satisfy the rest of the kernel.
Hence move the OMAP specific SMP boot functions to different header
instead of keeping them in 'plat/smp.h' which gets included indirectly
by linux/smp.h

NOTE!
This merge commit was created to fix compilation error. The block
tree was merged upstream and removed the 'elv_queue_empty()'
function which the new 'mtdswap' driver is using. So a simple
merge of the mtd tree with upstream does not compile. And the
mtd tree has already be published, so re-basing it is not an option.
To fix this unfortunate situation, I had to merge upstream into the
mtd-2.6.git tree without committing, put the fixup patch on top of
this, and then commit this. The result is that we do not have commits
which do not compile.
In other words, this merge commit "merges" 3 things: the MTD tree, the
upstream tree, and the fixup patch.

Currently IOVMM driver sets IOVMF_DA_FIXED/IOVMF_DA_ANON flags according
to input 'da' address when mapping memory:
da == 0: IOVMF_DA_ANON
da != 0: IOVMF_DA_FIXED
It prevents IOMMU to map first page with fixed 'da'. To avoid such
issue, IOVMM will not automatically set IOVMF_DA_FIXED. It should now
come from the user throught 'flags' parameter when mapping memory.
As IOVMF_DA_ANON and IOVMF_DA_FIXED are mutually exclusive, IOVMF_DA_ANON
can be removed. The driver will now check internally if IOVMF_DA_FIXED

The MMC controller on the OMAP2420 is different from those
on the OMAP2430, OMAP3 and OMAP4 families - all of the latter
are identical. The one on the OMAP2420 is closer to that
on OMAP1 chips.
Currently, the n8x0 is the only OMAP2420 platform supported
in mainline which registers the MMC controller. Upcoming
changes to register the controllers using hwmod data are
potentially invasive. To reduce the risk, separate out the
2420 controller registration from the common init function
and update its only user. Also seperating out mux settings

On OMAP4, the dpll post divider outputs (MX outputs)
along with clockout_x2 output provide a way to allow/deny
hardware level autogating.
Allowing autoidle would mean that the hw would autogate
this clock when there is no dependency for it.
Denying idle would mean that this clock output will be
forced to stay enabled.

Allow OMAP4 ES2.1 and ES2.2 revisions to be recognized in the
omap4_check_revision() function.
Mainly, ES2.1 has fixes that allow LPDDR to be used at 100% OPP (400MHz).
ES2.2 additionally has a couple of power management fixes (to reduce
leakage), an I2C1 SDA line state fix, and a floating point write
corruption fix (cortex erratum).
Even though the current mainline support doesn't need to distinguish
between ES2.X versions, it's still useful to know the correct silicon
rev when issues are reported. Moreover, these id checks can be used by
power management code that selects suitable OPPs considering the
memory speed limitation on ES2.0.

Cleans up all base address definitions for omap_mcspi

Changes involves:
1) Removing all base address macro defines.
2) Using omap-device layer to register device and utilizing data from
hwmod data file for base address, dma channel number, Irq_number,
device attribute(number of chipselect).
3) Appending base address with pdata reg_offset for omap4 boards.
For omap4 all regs used in driver deviate with reg_offset_macros
defined with an value of 0x100. So pass this offset through pdata
and append the same to base address retrieved from hwmod data file
and we are not mapping *_HL_* regs which are not used in driver.

This is due to the recent ARM init_sched_clock() changes and the late
initialization of the counter_32k clock source. More information here:
http://marc.info/?l=linux-omap&m=129513468605208&w=2
Fix by initializing the counter_32k clocksource during the machine timer
initialization.

A panel connects to one of the overlay managers of DSS through some interface block.
On OMAP4, specifying the type of the display is not sufficient to conclude which manager
the panel should be connected to.
Hence, a new member 'channel' is introduced in omap_dss_device structure to determine
which manager the panel uses. The dss_recheck_connections() called in dss_driver_probe()
uses this channel parameter to set the correct manager to the corresponding omap_dss_device.
The channel parameter is used only once to ensure the correct managers are set for each
panel. The parameter dssdev->manager->id will take care of ensuring that the panel and
then the interface driver configures the correct DISPC channel.
Also, add a new Overlay Manager in manager.c, make other changes needed for LCD2 channel.

On OMAP4, we have a new DISPC channel for Overlay Manager LCD2. There is a set
of regsiters for LCD2 channel similar to the existing LCD channel, like
DISPC_CONTROL2, DISPC_DIVISOR2, DISPC_CONFIG2 and so on.
Introduce new enum members for LCD2 Channel and corresponding Overlay Manager
in display.h.
Represent the following DISPC register defines with channel as a parameter
to differentiate between LCD and LCD2 registers (and also DIGIT in some cases):
DISPC_DEFAULT_COLOR, DISPC_TRANS_COLOR, DISPC_TIMING_H, DISPC_TIMING_V,
DISPC_POL_FREQ, DISPC_DIVISOR, DISPC_SIZE_LCD, DISPC_DATA_CYCLEk,
DISPC_CPR_COEF_R, DISPC_CPR_COEF_G and DISPC_CPR_COEF_B
This parametrization helps in reducing the number of register defines for DISPC.
Replace the existing reads/writes to these registers in this new way.
Also, Introduce defines for registers DISPC_CONTROL2 and DISPC_CONFIG2 which
are used exclusively for LCD2 channel.

Generic DPI panel driver includes the driver and 4 similar panel configurations. It
will match the panel name which is passed from platform data and setup the
right configurations.
With generic DPI panel driver, we can remove those 4 duplicated panel display
drivers. In the future, it is simple for us just add new panel configuration
date in panel-generic-dpi.c to support new display panel.
