[PATCH v3 1/5] ARM: dts: pxa: add pwri2c to pxa device-tree

From: Robert Jarzmik <robert.jarzmik@free.fr>
Date: 2015-02-07 12:39:52

pxa27x 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 pxa27x description.

Since v2: as Dmitry pointed out, no pwri2c on pxa25x, only pxa27x

[PATCH v3 5/5] ARM: dts: pxa: add pxa-timer to pxa27x

From: Robert Jarzmik <robert.jarzmik@free.fr>
Date: 2015-02-07 12:39:55

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.

Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr>

Since v1: removed clocksource node, pxa-timer being directly under
          pxabus (Rob's comment).
Since v2: renamed pxa-timer to timer (Sergei's comment)

[PATCH v3 2/5] ARM: dts: pxa: add clocks

From: Robert Jarzmik <robert.jarzmik@free.fr>
Date: 2015-02-07 12:41:01

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)

    The ePAPR standard tells to call such nodes "serial", not "uart".
