[PATCH v4 03/14] of: Make of_property_present() applicable to all kinds of property
From: Zijun Hu
Date: Thu Jan 09 2025 - 08:28:44 EST
From: Zijun Hu <quic_zijuhu@xxxxxxxxxxx>
API of_property_present() invokes of_property_read_bool() to check if
a property is present or not, and that has 2 shortcomings shown below:
- That narrows down property scope applicable to of_property_present()
from all kinds of property to only bool type.
- That is less logical since it says a property's presence is decided by
its bool property value.
Fix by making of_property_read_bool() invoke of_property_present().
