[PATCH v4 04/13] net: phy: micrel: Check RMII clock select property presence

[Stefano Radaelli]

From: Stefano Radaelli <stefano.r@xxxxxxxxxxxxx>

The micrel,rmii-reference-clock-select-25-mhz property is tested
for presence, but of_property_read_bool() warns when the property
has a value. Encoding it as <1> to satisfy the DT schema unit check
would therefore produce a warning at PHY probe.

Use of_property_present() for the presence test. It accepts both
existing empty properties and the new numeric form without changing
the RMII clock selection.

Signed-off-by: Stefano Radaelli <stefano.r@xxxxxxxxxxxxx>

v2->v3:
 - New patch: use of_property_present() for the RMII clock select
   property so its numeric form does not warn during PHY probe.
