Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/blackfin-2.6

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/cooloney/blackfin-2.6: (24 commits)
  [Blackfin] arch: import defines for BF547 -- it is just like the BF548, but no CAN
  [Blackfin] arch: fix build fails only include header files when enabled
  [Blackfin] arch: declare default INSTALL_PATH for Blackfin ports
  [Blackfin] arch: Encourage users to use the spidev character driver: Provide platform support
  [Blackfin] arch: Enable UART2 and UART3 for bf548
  [Blackfin] arch: Enable NET2272 on BF561-EZkit - remove request_mem_region
  [Blackfin] arch:Fix BUG [#3876] pfbutton test for BTN3 on bf533 don't show complete info
  [Blackfin] arch: remove duplicated definitions of the line discipline numbers N_* in asm-blackfin/termios.h
  [Blackfin] arch: fix building with mtd uclinux by putting the mtd_phys option into the function it actually gets used in
  [Blackfin] arch: simpler header and update dates
  [Blackfin] arch: move the init sections to the end of memory
  [Blackfin] arch: change the trace buffer control start/stop logic in the exception handlers
  [Blackfin] arch: fix typo in printk message
  [Blackfin] arch: this is an ezkit, not a stamp, so fixup the init function name
  [Blackfin] arch: add slightly better help text for CPLB_INFO
  [Blackfin] arch: Fix BUG - Enable ISP1362 driver to work ok with BF561
  [Blackfin] arch: Fix header file information
  [Blackfin] arch: Add Support for ISP1362
  [Blackfin] arch: add support for cmdline partitioning to the BF533-STAMP flash map driver and enable it as a module by default
  [Blackfin] arch: hook up set_irq_wake in Blackfin's irq code

help
Sleep "Deeper" Mode (High Power Savings) - This mode reduces dynamic
power dissipation by disabling the clock to the processor core (CCLK).
Furthermore, Standby sets the internal power supply voltage (VDDINT)
to 0.85 V to provide the greatest power savings, while preserving the
processor state.
The PLL and system clock (SCLK) continue to operate at a very low
frequency of about 3.3 MHz. To preserve data integrity in the SDRAM,
the SDRAM is put into Self Refresh Mode. Typically an external event
such as GPIO interrupt or RTC activity wakes up the processor.
Various Peripherals such as UART, SPORT, PPI may not function as
normal during Sleep Deeper, due to the reduced SCLK frequency.
When in the sleep mode, system DMA access to L1 memory is not supported.
