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 --- v2->v3: - New patch: use of_property_present() for the RMII clock select property so its numeric form does not warn during PHY probe. drivers/net/phy/micrel.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/net/phy/micrel.c b/drivers/net/phy/micrel.c index ae830781824b..acb481a29c25 100644 --- a/drivers/net/phy/micrel.c +++ b/drivers/net/phy/micrel.c @@ -2791,7 +2791,7 @@ static int kszphy_probe(struct phy_device *phydev) if (type) priv->rmii_ref_clk_sel = type->has_rmii_ref_clk_sel; - rmii_ref_clk_sel_25_mhz = of_property_read_bool(np, + rmii_ref_clk_sel_25_mhz = of_property_present(np, "micrel,rmii-reference-clock-select-25-mhz"); if (rate > 24500000 && rate < 25500000) { -- 2.47.3
