+Subject: net: phy: meson-gxl: Add generic dummy stubs for MMD register access
+
+From: Chris Healy <healych@amazon.com>
+
+commit afc2336f89dc0fc0ef25b92366814524b0fd90fb upstream.
+
+The Meson G12A Internal PHY does not support standard IEEE MMD extended
+register access, therefore add generic dummy stubs to fail the read and
+write MMD calls. This is necessary to prevent the core PHY code from
+erroneously believing that EEE is supported by this PHY even though this
+PHY does not support EEE, as MMD register access returns all FFFFs.
+
+Fixes: 5c3407abb338 ("net: phy: meson-gxl: add g12a support")
