The files in include/mach are only used from mach/davinci, so they are no longer needed in the traditional location. Move them to arch/arm/mach-davinci/ and drop the logic for the special include path. The mach/uncompress.h file is not used at all and can just be removed.

|
|
* Note on SLEEPCOUNT:
|
|
* The SLEEPCOUNT feature is mainly intended for cases in which
|
|
* the internal oscillator is used. The internal oscillator is
|
|
* fully disabled in deep sleep mode. When you exist deep sleep
|
|
* mode, the oscillator will be turned on and will generate very
|
|
* small oscillations which will not be detected by the deep sleep
|
|
* counter. Eventually those oscillations will grow to an amplitude
|
|
* large enough to start incrementing the deep sleep counter.
|
|
* In this case recommendation from hardware engineers is that the
|
|
* SLEEPCOUNT be set to 4096. This means that 4096 valid clock cycles
|
|
* must be detected before the clock is passed to the rest of the
|
|
* system.
|
|
* In the case that the internal oscillator is not used and the
|
|
* clock is generated externally, the SLEEPCOUNT value can be very
|
|
* small since the clock input is assumed to be stable before SoC
|
|
* is taken out of deepsleep mode. A value of 128 would be more than
|
|
* adequate.
