+Subject: [PATCH] net: phy: at803x: select correct page on config init
+
+The Atheros AR8031 and AR8033 expose different registers for SGMII/Fiber
+as well as the copper side of the PHY depending on the BT_BX_REG_SEL bit
+in the chip configure register.
+
+The driver assumes the copper side is selected on probe, but this might
+not be the case depending which page was last selected by the
+bootloader. Notably, Ubiquiti UniFi bootloaders show this behavior.
+
+Select the copper page when probing to circumvent this.

+Subject: [PATCH] net: phy: at803x: fix probe error if copper page is selected
+
+The commit c329e5afb42f ("net: phy: at803x: select correct page on
+config init") selects the copper page during probe. This fails if the
+copper page was already selected. In this case, the value of the copper
+page (which is 1) is propagated through phy_restore_page() and is
+finally returned for at803x_probe(). Fix it, by just using the
+at803x_page_write() directly.
+
+Also in case of an error, the regulator is not disabled and leads to a
+WARN_ON() when the probe fails. This couldn't happen before, because
+at803x_parse_dt() was the last call in at803x_probe(). It is hard to
+see, that the parse_dt() actually enables the regulator. Thus move the
+regulator_enable() to the probe function and undo it in case of an
+error.
