      clocksource: add samsung pwm timer driver · f1189989
      Tomasz Figa authored
      
      
      This adds a new clocksource driver for the PWM timer that is
      present in most Samsung SoCs, based on the existing driver in
      arch/arm/plat-samsung/samsung-time.c and many changes implemented by
      Tomasz Figa.
      
      Originally, the conversion of all Samsung machines to the new driver was
      planned for 3.10, but that work ended up being too late and too invasive
      just before the merge window.
      
      Unfortunately, other changes in the Exynos platform resulted in some
      Exynos4 setups, particularly the Universal C210 board to be broken. In
      order to fix that with minimum risk, so we now leave the existing pwm
      clocksource driver in place for all older platforms and use the new
      driver only for device tree enabled boards. This way, we can get the
      broken machines running again using DT descriptions.
      
      All clocksource changes were implemented by Tomasz, while the DT
      registration was rewritten by Arnd.

      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.

      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.
