      drivers/video: fsl-diu-fb: rename "machine_data" to "data" · b7795052
      Timur Tabi authored 
      "machine_data" is too long and clunky, and the "machine" part doesn't make
much sense, anyway.

      video: s3c-fb: add shadow register protect · ff8c9107
      Jingoo Han authored 
      Shadow registers should be protectd whenever the registers are
updated. Shadow registers are updated after SHADOWCON shadow
register is cleared.

      video: s3c-fb: modify runtime pm functions · 35784b43
      Jingoo Han authored 
      Runtime suspend and runtime resume are modified in order to
reduce the complexity and improve the usability of runtime pm.
After probe function, s3c-fb driver is not suspended until
suspend or remove is called.

The scheme is changed as follows:
 runtime_get is only called in probe and resume.
 runtime_put is only called in remove and suspend.
 open/close cannot call the runtime_get/put.

Also, runtime_susepnd/resume are just called by runtime pm,
not doing suspend/resume routine any longer. This is because
open/close cannot call the runtime_get/put; the suspend/resume
routine in runtime_suspend/resume were previously used when
open and close were called.

The name of s3c-fb dev_pm_ops is changed from s3cfb_pm_ops to
s3c_fb_pm_ops in order to use more consistent naming.

      drivers/video: fsl-diu-fb: merge all allocated data into one block · ddd3d905
      Timur Tabi authored 
      The Freescale DIU driver allocates multiple blocks of memory, including
multiple DMA buffers.  Merge all of these blocks into one data structure.

Specifically:

1) struct fsl_diu_data now contains everything that needs to be allocated,
except for the framebuffers themselves.  DMA'able objects are aligned correctly
within the structure.

2) struct diu_addr is no longer needed, because we don't have to manage
multiple blocks of DMA memory.

3) Since there's no diu_addr any more, macro DMA_ADDR is used to calculate
the DMA address of any field in fsl_diu_data.

4) Functions allocate_buf() and free_buf() are no longer needed, because we
now assume that dma_alloc_coherent() will allocate a page-aligned block,
and everything is properly aligned with fsl_diu_data already, so we no longer
need to align any memory blocks ourselves.

5) The "dummy" area descriptor is now defined separately from the other
five ADs, so NUM_AOIS (previously called FSL_AOI_NUM) is now set to five
instead of six.  Previously, all six were combined together to avoid a
separate call to allocate_buf() just for the dummy AD.

6) framebuffer_alloc() and framebuffer_release() are no longer used.  The
framebuffer is initialized manually.

7) Error handling is simplified since there's only one memory buffer
allocated.

      This patch set missing bitmask of enabled hardware window which
should be checked whenever the hardware window is enabled.
