[PATCH 1/5] ARM: dts: pxa: add pwri2c to pxa device-tree

From: Robert Jarzmik <robert.jarzmik@free.fr>
Date: 2015-01-31 22:49:01 

Each pxa variant has 2 I2C busses on the SoC :
 - the casual I2C
 - the power I2C, normally driving power regulators, and capable of
 receiving orders on core frequency modifications

Add the missing pwri2c to pxa description.

Each pxa27x has an embedded usb udc controller. Add it in the pxa27x
device-tree description.

[PATCH 5/5] ARM: dts: pxa: add pxa-timer to pxa27x

From: Robert Jarzmik <robert.jarzmik@free.fr>
Date: 2015-01-31 22:48:59 

Each pxa has an embedded OS Timers IP. The kernel cannot work without a
valid clocksource, and this adds the OS Timers to the pxa device-tree
description.

There is absolutely no need for this container node.

Please get rid of it and place the node below directly under the parent
node.

Mark.

[PATCH 2/5] ARM: dts: pxa: add clocks

    

      From: Robert Jarzmik <robert.jarzmik@free.fr>

      Date: 2015-01-31 22:49:21 
    

  

  
Add clocks to the IPs already described in the pxa device-tree
files. There are more clocks in the clock tree than IPs described in the
current pxa device-tree.

This patch ensures that :
 - the current description is correct
 - the clocks are actually claimed, so that clock framework doesn't
   disable them automatically (unused clocks shutdown)
