      drm/nouveau/fbcon: fix font width not divisible by 8 · 28668f43
      Mikulas Patocka authored
      The patch f045f459 ("drm/nouveau/fbcon: fix out-of-bounds memory accesses")
      tries to fix some out of memory accesses. Unfortunatelly, the patch breaks the
      display when using fonts with width that is not divisiable by 8.
      
      The monochrome bitmap for each character is stored in memory by lines from top
      to bottom. Each line is padded to a full byte.
      
      For example, for 22x11 font, each line is padded to 16 bits, so each
      character is consuming 44 bytes total, that is 11 32-bit words. The patch
      f045f459 changed the logic to "dsize = ALIGN(image->width *
      image->height, 32) >> 5", that is just 8 words - this is incorrect and it
      causes display corruption.
      
      This patch adds the necesary padding of lines to 8 bytes.
      
      This patch should be backported to stable kernels where f045f459 was
      backported.

      This adds drm bridge support for the NXP/Freescale DCU. The patchset
      has been discussed on the mailing list since quite some time...
      Plus there is a small fix provided by Peter.

      Dave Airlie authored
      This time, a bunch of cleanups and refactoring work so that we can get
      dt bindings upstream.  In general, we keep compatibility with existing
      downstream bindings as much as possible, to make backports to device
      kernels easier, but now we have cleaner upstream bindings so that we
      can start landing gpu/display support in upstream dts files.
      
      Plus shrinker and madvise support, which has been on my todo list for
      a long time.  And support for arbitrary # of cmd bufs in submit ioctl
      (I've got libdrm+mesa userspace for this on branches) to enable some
      of the mesa batch/reorder stuff I'm working on.  Userspace decides
      whether this is supported based on advertised driver version.  For the
      interesting userspace bits, see:

      Plus support for ASoC hdmi audio codec, and few other random other
      cleanups.

      drm: rcar-du: Remove i2c slave encoder interface for hdmi encoder · 1d926114
      Archit Taneja authored
      The hdmi output in rcar-du uses the i2c slave encoder interface to link
      to the adv7511 encoder chip. The kms driver creates encoder and connector
      entities that internally uses the drm_encoder_slave_funcs ops provided by
      the slave encoder driver.
      
      Change the driver such that it expects a bridge entity instead of a slave
      encoder. The hdmi connector code isn't needed anymore as we expect the
      adv7511 bridge driver to create/manage the connector.
      
      Note that the kms driver still expects a connector node for hdmi to be
      present in DT. This node has no connection to the connector created
      by the bridge driver.
