Pull char/misc driver merge from Greg Kroah-Hartman:
 "Here is the "big" char/misc driver tree update for the 3.7-rc1 merge
  window.

  Nothing major, just a number of driver updates and fixes, all of which
  have been in the linux-next releases for a while now either in my
  tree, or in Andrew's (the lis3l driver changes came from his tree last
  week).

+
+This device is matched via its bus drivers, and has a number of properties
+that apply in on the generic device (independent from the bus).
+
+
+Required properties for the SPI bindings:
+ - compatible: 		should be set to "st,lis3lv02d_spi"
+ - reg:			the chipselect index
+ - spi-max-frequency:	maximal bus speed, should be set to 1000000 unless
+			constrained by external circuitry
+ - interrupts:		the interrupt generated by the device
+
+Required properties for the I2C bindings:
+ - compatible:		should be set to "st,lis3lv02d"
+ - reg:			i2c slave address
+ - Vdd-supply:		The input supply for Vdd
+ - Vdd_IO-supply:	The input supply for Vdd_IO
+
+
+Optional properties for all bus drivers:
+
+ - st,click-single-{x,y,z}:	if present, tells the device to issue an
+				interrupt on single click events on the
+				x/y/z axis.
+ - st,click-double-{x,y,z}:	if present, tells the device to issue an
+				interrupt on double click events on the
+				x/y/z axis.
+ - st,click-thresh-{x,y,z}:	set the x/y/z axis threshold
+ - st,click-click-time-limit:	click time limit, from 0 to 127.5msec
+				with step of 0.5 msec
+ - st,click-latency:		click latency, from 0 to 255 msec with
+				step of 1 msec.
+ - st,click-window:		click window, from 0 to 255 msec with
+				step of 1 msec.
+ - st,irq{1,2}-disable:		disable IRQ 1/2
+ - st,irq{1,2}-ff-wu-1:		raise IRQ 1/2 on FF_WU_1 condition
+ - st,irq{1,2}-ff-wu-2:		raise IRQ 1/2 on FF_WU_2 condition
