Patrice Chotard 0e04ce02e6 ARM: dts: STi: Remove unused clk_ext2f_a9 clock
This clock node is unused, remove it.
This allows to fix the following warnings when compiling
dtb with W=1 option :

arch/arm/boot/dts/stih410-b2120.dtb: Warning (simple_bus_reg):
Node /clocks/clockgen-c0 missing or empty reg/ranges property

arch/arm/boot/dts/stih410-b2260.dtb: Warning (simple_bus_reg):

Patrice Chotard d6d854cc1c ARM: dts: STi: Fix bindings notation
Remove leading 0x and 0s from bindings notation
Add missing unit-address and remove some which are useless.

This allows to fix several warnings like :

Warning (unit_address_vs_reg): Node XXXX has a reg or ranges property, but no unit name
Warning (simple_bus_reg): Node XXXX simple-bus unit address format error, expected "123456"
Warning (unit_address_vs_reg): Node XXXX has a unit name, but no reg property

Rob Herring 8dccafaa28 arm: dts: fix unit-address leading 0s
Fix dtc warnings for 'simple_bus_reg' due to leading 0s. Converted using
the following command:

perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find arch/arm/boot/dts -type -f -name '*.dts*'

Dropped changes to ARM, Ltd. boards LED nodes and manually fixed up some
occurrences of uppercase hex.

Peter Griffin 97a0b97f9e ARM: dts: stih410-clocks: Add PROC_STFE as a critical clock
Once the ST frontend demux HW IP has been enabled, the clock can't
be disabled otherwise the system will hang and the board will
be unserviceable.

To allow balanced clock enable/disable calls in the driver we use
the critical clock infrastructure to take an extra reference on the
clock so the clock will never actually be disabled.

Lee Jones f221d8100e ARM: sti: stih410-clocks: Identify critical clocks
Lots of platforms contain clocks which if turned off would prove fatal.
The only way to recover is to restart the board(s).  This driver takes
references to clocks which are required to be always-on.  The Common
Clk Framework will then take references to them.  This way they will
not be turned off during the clk_disabled_unused() procedure.

In this patch we are identifying clocks, which if gated would render
the STiH410 development board unserviceable.
