Add a debugfs node called "summary" to /sys/kernel/debug/clock/
that displays a quick summary of all clocks registered in the
"clocks" structure. The format of the output from this node is:
<clock-name> <parent-name> <rate> <usecount>
This debugfs node was very helpful for taking a quick snapshot of
the linux clock tree for OMAP and ensuring clock frequencies
calculated by the kernel were indeed correct. This patch helped
uncover some bugs in the linux clock tree for OMAP4.

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.

Since we cannot trust (or even reliably find) the OMAP I2C
peripheral unit's own revision register, we must inform the
OMAP i2c driver of which IP version it is running on. We
do this by tagging the omap_hwmod_class for i2c on all the
OMAP2+ platform / cpu specific hwmod init and passing it up
to the driver (next patches).

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.

Peter Maydell noticed when running under QEMU he was getting
errors reporting 32-bit access to I2C peripheral unit registers
that are documented to be 8 or 16-bit only[1][2]
The I2C driver is blameless as it wraps its accesses in a
function using __raw_writew and __raw_readw, it turned out it
is the hwmod stuff.
However the hwmod code already has a flag to force a
perhipheral unit to only be accessed using 16-bit operations.
This patch applies the 16-bit only flag to the 2430,
OMAP3xxx and OMAP44xx hwmod structs. 2420 was already
correctly marked up as 16-bit.
The 2430 change will need testing by TI as arranged
in the comments to the previous patch version.
When the 16-bit flag is or-ed with other flags, it is placed
first as requested in comments.

Currently using pm_runtime with DSS requires the DSS driver to enable
the DSS functional clock before calling pm_runtime_get(). That makes it
impossible to use pm_runtime in DSS as it is meant to be used, with
pm_runtime callbacks.
This patch changes the hwmod database for OMAP4 so that enabling the
hwmod via pm_runtime will also enable the DSS functional clock, allowing
us to use pm_runtime properly in DSS driver.
The DSS HWMOD side is not really correct, not before nor after this
patch, and getting DSS to retention will probably not work currently.
However, it is not supported in the mainline kernel anyway, so this
won't break anything.
So this patch allows us to write the pm_runtime adaptation for the DSS
driver the way it should be done, and the HWMOD/PM side can be fixed
later.

On OMAP4430 devices, because of boot ROM code bug, MPU OFF state can't
be attempted independently. When coming out of MPU OFF state, ROM code
disables the clocks of IVAHD, TESLA which is not desirable. Hence the
MPU OFF state is not usable on OMAP4430 devices.
OMAP4460 onwards, MPU OFF state will be descoped completely because
the DDR firewall falls in MPU power domain. When the MPU hit OFF state,
DDR won't be accessible for other initiators. The deepest state supported
is open switch retention (OSWR) just like CORE and PER PD on OMAP4430.
So in summary MPU power domain OFF state is not supported on OMAP4
and onwards designs. Thanks to new PRCM design, device off mode can
still be achieved with power domains hitting OSWR state.

On OMAP4, CPU accesses on unmapped addresses are redirected to GPMC by
L3 interconnect. Because of CPU speculative nature, such accesses are
possible which can lead to indirect access to GPMC and if it's clock is
not running, it can result in hang/abort on the platform.
Above makes access to GPMC unpredictable during the execution, so it's
module mode needs to be kept under hardware control instead of software
control.
Since the auto gating is supported for GPMC, there isn't any power impact
because of this change.
The issue was un-covered with security middleware running along with HLOS.
In this case GPMC had a valid MMU descriptor on secure side where as HLOS
didn't map the GMPC because it isn't being used.
