stable inclusion from stable-v5.10.168 commit 98c93a01608f23a28a3c9e6736f74d078fa8400f category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I7URR4 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=98c93a01608f23a28a3c9e6736f74d078fa8400f ---------------------------------------------------- [ Upstream commit afc2336f ] 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.
