        by proc_ns_follow_link were found by Dave Jones.
      
        I am including the enhancement for mount to only trigger requests of
        filesystem modules here instead of delaying this for the 3.10 merge
        window because it is both trivial and the kind of change that tends to
        bit-rot if left untouched for two months."

      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.

      proc: Use nd_jump_link in proc_ns_follow_link · db04dc67
      Eric W. Biederman authored
      Update proc_ns_follow_link to use nd_jump_link instead of just
      manually updating nd.path.dentry.
      
      This fixes the BUG_ON(nd->inode != parent->d_inode) reported by Dave
      Jones and reproduced trivially with mkdir /proc/self/ns/uts/a.
      
      Sigh it looks like the VFS change to require use of nd_jump_link
      happend while proc_ns_follow_link was baking and since the common case
      of proc_ns_follow_link continued to work without problems the need for
      making this change was overlooked.

      Platform: x86: chromeos_laptop : Add basic platform data for atmel devices · 2ef39204
      Benson Leung authored
      Add basic platform data to get the current upstream driver working
      with the 224s touchpad and 1664s touchscreen.
      We will be using NULL config so we will use the settings from the
      devices' NVRAMs.

      Input: atmel_mxt_ts - Support for touchpad variant · 22dfab7f
      Daniel Kurtz authored
      This same driver can be used by atmel based touchscreens and touchpads
      (buttonpads). Platform data may specify a device is a touchpad
      using the is_tp flag.
      
      This will cause the driver to perform some touchpad specific
      initializations, such as:
        * register input device name "Atmel maXTouch Touchpad" instead of
        Touchscreen.
        * register BTN_LEFT & BTN_TOOL_* event types.
        * register axis resolution (as a fixed constant, for now)
        * register BUTTONPAD property
        * process GPIO buttons using reportid T19
      
      Input event GPIO mapping is done by the platform data key_map array.
      
      key_map[x] should contain the KEY or BTN code to send when processing
      GPIOx from T19. To specify a GPIO as not an input source, populate
      with KEY_RESERVED, or 0.

      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.

      drm/mgag200: Reject modes that are too big for VRAM · 0ba53171
      Christopher Harvey authored
      A monitor or a user could request a resolution greater than the
      available VRAM for the backing framebuffer. This change checks 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
      in via the video= parameter.
