Compared to its OMAP cousin, there's no current support for

davinci: Add compare register support to timer code
The Timer64p timer has 8 compare registers that can
be used to generate interrupts when the timer value
matches the compare reg's value. They do not disturb
the timer itself. This can be useful when there is
only one timer available for both clock events and
clocksource.
When enabled, the clocksource remains a continuous
32-bit counter but the clock event will no longer
support periodic interrupts. Instead only oneshot
timers will be supported and implemented by setting
the compare register to the current timer value plus
the period that the clock event subsystem is requesting.
Compare registers support is enabled automatically
when the following conditions are met:
1) The same timer is being used for clock events
and clocksource.
2) The timer is the bottom half (32 bits) of the
64-bit timer (hardware limitation).
3) The the compare register offset and irq are
not zero.
Since the timer is always running, there is a hardware
race in timer32_config() between reading the current
timer value, and adding the period to the current
timer value and writing the compare register.
Testing on a da830 evm board with the timer clocked
at 24 MHz and the processor clocked at 300 MHz,
showed the number of counter ticks to do this ranged
from 20-53 (~1-2.2 usecs) but usually around 41 ticks.
This includes some artifacts from collecting the
information. So, the minimum period should be
at least 5 usecs to be safe.
There is also an non-critical lower limit that
the period should be since there is no point in
setting an event that is much shorter than the
time it takes to set the event, and get & handle
the timer interrupt for that event. There can
also be all sorts of delays from activities
occuring elsewhere in the system (including
hardware activitis like cache & TLB management).
These are virtually impossible to quantify so a
minimum period of 50 usecs was chosen. That will
certianly be enough to avoid the actual hardware
race but hopefully not large enough to cause
unreasonably course-grained timers.

OMAP3: PM: UART: disable clocks when idle and off-mode support
This patch allows the UART clocks to be disabled when the OMAP UARTs
are inactive, thus permitting the chip to hit retention in idle.
After the expiration of an activity timer, each UART is allowed to
disable its clocks so the system can enter retention. The activity
timer is (re)activated on any UART interrupt, UART wake event or any
IO pad wakeup. The actual disable of the UART clocks is done in the
'prepare_idle' hook called from the OMAP idle loop.
While the activity timer is active, the smart-idle mode of the UART is
also disabled. This is due to a "feature" of the UART module that
after a UART wakeup, the smart-idle mode may be entered before the
UART has communicated the interrupt, or upon TX, an idle mode may be
entered before the TX FIFOs are emptied.
Upon suspend, the 'prepare_suspend' hook cancels any pending activity
timers and allows the clocks to be disabled immediately.
In addition, upon disabling clocks the UART state is saved in case
of an off-mode transition while clocks are off.
Special thanks to Tero Kristo for the initial ideas and first versions
of UART idle support, and to Jouni Hogander for extra testing and
bugfixes.

the same base address. This isn't true on some newer SoCs.
To solve this, have the SoC-specific code set the JTAG ID register
base address in soc_info structure and add a 'cpu_id' member to it.
'cpu_id' will be used by the cpu_is_davinci_*() macros to match
the cpu id. Also move the info used to identify the cpu type into
the SoC-specific code to keep all SoC-specific code together.
The common code will read the JTAG ID register, search through
an array of davinci_id structures to identify the cpu type.
Once identified, it will set the 'cpu_id' member of the soc_info

davinci: Encapsulate SoC-specific data in a structure
Create a structure to encapsulate SoC-specific information.
This will assist in generalizing code so it can be used by
different SoCs that have similar hardware but with minor
differences such as having a different base address.
The idea is that the code for each SoC fills out a structure
with the correct information. The board-specific code then
calls the SoC init routine which in turn will call a common
init routine that makes a copy of the structure, maps in I/O
regions, etc.
After initialization, code can get a pointer to the structure
by calling davinci_get_soc_info(). Eventually, the common
init routine will make a copy of all of the data pointed to
by the structure so the original data can be made __init_data.
That way the data for SoC's that aren't being used won't consume
memory for the entire life of the kernel.
The structure will be extended in subsequent patches but
initially, it holds the map_desc structure for any I/O
regions the SoC/board wants statically mapped.

davinci: use 32-bit accesses for low-level debug macros
This patch defines debug macros for low-level debugging for Davinci
based platforms
Tested on :
- DM644x DaVinci EVM
- DM646X DaVinciHD EVM
- DM355 EVM
This patch attempts to solve the low-level debug issue in DM646x. The
UART on DM646x SoC allows only 32-bit access. The existing
debug-macro.S uses the macros from debug-8250.S file. This led to
garbage serial out in the case of DM646x.
The inclusion of debug-8250.S does not allow for run time fix for this
issue. There are compile time errors due to multiple definitions of
the macros. Also when building a single image for multiple DaVinci
Platforms, the ifdefs cannot be relied upon.
The solution below does not include the debug-8250.S file and defines
the necessary macros. This solution was arrived at after observing
that word access does not affect the low-level debug messages on
DM644x/DM355.
The other approach to this issue is to use the UART module information
available in the peripheral registers to decide the access
mechanism. But this will have to be done for every access of UART
specifically for DM646x. Also this calls for a modification of the
debug-8250.S file.
