Unlike the majority of other SOCs the PWM node uses ehrpwm instead of
the generic pwm node name. This patch series switches to the pwm node
name and while at it fix some other minor binding documentation issues.
This patch series also includes a patch to insure ABI compatibility.
This series was tested on AM335x and AM437x GP evm. I also validated that
ABI compatibility was maintained.
V3 changes:
Update am335x-shc.dts
V2 changes:
Dropped patches related to the ranges property.

Add tblck to the pwm nodes. This insures that the ehrpwm driver has access
to the time-based clk.
Do not remove similar entries for ehrpwm node. Later patches will switch
from using ehrpwm node name to pwm. But to maintain ABI compatibility we
shouldn't remove the old entries.

The series that adds support for the hwmod clock type for OMAPs has a
support patch that should address this problem at least partially; I am
planning to post next rev of that set soonish. It should allow getting
rid of majority of the clock aliases, I will remove any aliases I can at
the same time.

Now that the node name has been changed from ehrpwm to pwm the document
should show this proper usage. Also change the unit address in the example
from 0 to the proper physical address value that should be used.
