      ARM: 5673/1: U300 fix initsection compile warning · a2bb9f4d
      Linus Walleij authored
      The u300_init_check_chip() function was not properly tagged with
      the __init macro and provided a initsection mismatch on
      compilation.

      ARM: Fix broken highmem support · dde5828f
      Russell King authored
      Currently, highmem is selectable, and you can request an increased
      vmalloc area.  However, none of this has any effect on the memory
      layout since a patch in the highmem series was accidentally dropped.
      Moreover, even if you did want highmem, all memory would still be
      registered as lowmem, possibly resulting in overflow of the available
      virtual mapping space.
      
      The highmem boundary is determined by the highest allowed beginning
      of the vmalloc area, which depends on its configurable minimum size
      (see commit 60296c71 for details on
      this).
      
      We should create mappings and initialize bootmem only for low memory,
      while the zone allocator must still be told about highmem.
      
      Currently, memory nodes which are completely located in high memory
      are not supported.  This is not a huge limitation since systems
      relying on highmem support are unlikely to have discontiguous memory
      with large holes.
      
      [ A similar patch was meant to be merged before commit 5f0fbf9e
        and be available  in Linux v2.6.30, however some git rebase screw-up
        of mine dropped the first commit of the series, and that goofage
        escaped testing somehow as well. -- Nico ]

      sh: sh7724 ddr self-refresh changes · 237674e0
      Magnus Damm authored
      This patch updates the SuperH Mobile sleep assembly code with
      support for DBSC memory controller found in the sh7724 processor.
      
      Without this fix the memory hooked up to the sh7724 processor
      will never enter self-refresh mode before suspending to ram. The
      effect of this is that the memory contents most likeley will be
      lost upon resume which may or may not be what you want.

      sh: use in-soc KEYSC on se7724 · 9747e78b
      Magnus Damm authored
      This patch updates the Solution Engine 7724 board code to use
      in-SoC KEYSC resources for the keyboard platform device. Using
      the in-SoC key scan controller fixes a crash-during-resume issue.
      
      Without this patch the KEYSC hardware block located in the board
      specific FPGA is used together with an external IRQ which is
      routed through the FPGA and handled by some board specific demux
      code. This board specific FPGA interrupt code does not implement
      desc->set_wake() so the enable_irq_wake() call in the sh_keysc
      driver will fail at suspend-to-ram time and the disable_irq_wake()
      will bomb out when resuming.
      
      Changing the platform data to use the in-SoC KEYSC hardware makes
      the se7724 board support code less special which is a good thing.
      Also, the board specific KEYSC pin setup code selects in-SoC pin
      functions already which makes the current FPGA platform device data
      look like a typo.

      sh: CMT suspend/resume · f6431732
      Magnus Damm authored
      This patch updates the SuperH CMT driver with suspend and resume
      callbacks for the suspend-to-ram case. This patch stops the CMT
      channel at suspend time to avoid unwanted wake up events.
