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

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".
