Subject: [PATCH v3 4/7] of: property: Use of_property_present() for
 of_fwnode_property_present()

From: Zijun Hu <quic_zijuhu@...cinc.com>

Use of_property_present() instead of of_property_read_bool() for
of_fwnode_property_present() since the former is more applicable
obviously.

Hi Rob,

i pick up this change again after some considerations as below:

1) of_property_present() is more suitable than of_property_read_bool()
   here, deprecated API is not main reason.

2) it does not conflict with your job which warns when use
   of_property_read_bool() for non-bool property.
