From: Chris Healy Date: Mon, 30 Jan 2023 23:14:02 +0000 (-0800) Subject: net: phy: meson-gxl: Add generic dummy stubs for MMD register access X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=afc2336f89dc0fc0ef25b92366814524b0fd90fb;p=linux.git net: phy: meson-gxl: Add generic dummy stubs for MMD register access 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.
