Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:
 "This series include:
   - a new Remote Controller driver for ST SoC with the corresponding DT
     bindings
   - a new frontend (cx24117)
   - a new I2C camera flash driver (lm3560)
   - a new mem2mem driver for TI SoC (ti-vpe)
   - support for Raphael r828d added to r820t driver
   - some improvements on buffer allocation at VB2 core
   - usual driver fixes and improvements

  PS this time, we have a smaller number of patches.  While it is hard
  to pinpoint to the reasons, I believe that it is mainly due to:

   1) there are several patch series ready, but depending on DT review.
      I decided to grant some extra time for DT maintainers to look on
      it, as they're expecting to have more time with the changes agreed
      during ARM mini-summit and KS.  If they can't review in time for
      3.14, I'll review myself and apply for the next merge window.

   2) I suspect that having both LinuxCon EU and LinuxCon NA happening
      during the same merge window affected the development
      productivity, as several core media developers participated on
      both events"

+Device-Tree bindings for ST IRB IP
+
+Required properties:
+	- compatible: Should contain "st,comms-irb".
+	- reg: Base physical address of the controller and length of memory
+	  mapped region.
+	- interrupts: interrupt-specifier for the sole interrupt generated by
+	  the device. The interrupt specifier format depends on the interrupt
+	  controller parent.
+	- rx-mode: can be "infrared" or "uhf". This property specifies the L1
+	  protocol used for receiving remote control signals. rx-mode should
+	  be present iff the rx pins are wired up.
+	- tx-mode: should be "infrared". This property specifies the L1
+	  protocol used for transmitting remote control signals. tx-mode should
+	  be present iff the tx pins are wired up.
+
+Optional properties:
+	- pinctrl-names, pinctrl-0: the pincontrol settings to configure muxing
+	  properly for IRB pins.
+	- clocks : phandle with clock-specifier pair for IRB.
+
+Example node:
+
+	rc: rc@fe518000 {
+		compatible	= "st,comms-irb";
+		reg		= <0xfe518000 0x234>;
+		interrupts	= <0 203 0>;
+		rx-mode		= "infrared";
