      videomode: videomode_from_timing work · 6cd2c7db
      Tomi Valkeinen authored
      
      
      We currently have videomode_from_timing(), which takes one
      display_timing entry from display_timings.
      
      To make it easier to use display_timing without display_timings, this
      patch renames videomode_from_timing() to videomode_from_timings(), and
      adds a new videomode_from_timing() which just converts a given
      display_timing to videomode.

      videomode: remove timing_entry_index · 694f0506
      Tomi Valkeinen authored
      
      
      Display timing's fields have minimum, typical and maximum values. These
      can be accessed by using timing_entry_index enum, and
      display_timing_get_value() function.
      
      There's no real need for this extra complexity. The values can be
      accessed more easily by just using the min/typ/max fields.

      videomode: create enum for videomode's display flags · 32ed6ef1
      Tomi Valkeinen authored
      
      
      Instead of having plain defines for the videomode's flags, add an enum
      for the flags. This makes the flags clearer to use, as the enum tells
      which values can be used with the flags field.

      videomode: combine videomode dmt_flags and data_flags · 06a33079
      Tomi Valkeinen authored
      
      
      Both videomode and display_timing contain flags describing the modes.
      These are stored in dmt_flags and data_flags. There's no need to
      separate these flags, and having separate fields just makes the flags
      more difficult to use.
      
      This patch combines the fields and renames VESA_DMT_* flags to
      DISPLAY_FLAGS_*.

      videomode: simplify videomode Kconfig and Makefile · a38884f6
      Tomi Valkeinen authored
      
      
      This patch simplifies videomode related Kconfig and Makefile. After this
      patch, there's only one non-user selectable Kconfig option left,
      VIDEOMODE_HELPERS. The reasons for the change:
      
      * Videomode helper functions are not something that should be shown in
        the kernel configuration options. The related code should just be
        included if it's needed, i.e. selected by drivers using videomode.
      
      * There's no need to have separate Kconfig options for videomode and
        display_timing. First of all, the amount of code for both is quite
        small. Second, videomode depends on display_timing, and display_timing
        in itself is not really useful, so both would be included in any case.
      
      * CONFIG_VIDEOMODE is a bit vague name, and CONFIG_VIDEOMODE_HELPERS
        describes better what's included.

      Atmel MXT touchscreen: increase reset timeouts · 8343bce1
      Linus Torvalds authored
      
      
      There is a more complete atmel patch-series out by Nick Dyer that fixes
      this and other things, but in the meantime this is the minimal thing to
      get the touchscreen going on (at least my) Pixel Chromebook.
      
      Not that I want my dirty fingers near that beautiful screen, but it
      seems that a non-initialized touchscreen will also end up being a
      constant wakeup source, so you have to disable it to go to sleep.  And
      it's easier to just fix the initialization sequence.

      drm/tegra: drop "select DRM_HDMI" · 36c1813b
      Paul Bolle authored
      Commit ac24c220
      
       ("drm/tegra: Use generic
      HDMI infoframe helpers") added "select DRM_HDMI" to the DRM_TEGRA
      Kconfig entry. But there is no Kconfig symbol named DRM_HDMI. The select
      statement for that symbol is a nop. Drop it.
      
      What was needed to use HDMI functionality was to select HDMI (which this
      entry already did through depending on DRM) and to include linux/hdmi.h
      (which this commit also did).

      drm/mgag200: Bug fix: Renesas board now selects native resolution. · ce495960
      Julia Lemire authored
      
      
      Renesas boards were consistently defaulting to the 1024x768 resolution,
      regardless of the native resolution of the monitor plugged in.  It was
      determined that the EDID of the monitor was not being read.  Since the
      DAC is a shared line, in order to read from or write to it we must take
      control of the DAC clock.  This can be done by setting the proper
      register to one.
      
      This bug fix sets the register MGA1064_GEN_IO_CTL2 to one.  The DAC
      control line can be used to determine whether or not a new monitor has
      been plugged in.  But since the hotplug feature is not one we will
      support, it has been decided to simply leave the register set to one.

      A monitor or a user could request a resolution greater than the

      required framebuffer size against the max VRAM size and rejects modes
      if they are too big. This change can also remove a mode request passed
