Subject: [PATCH net-next v2 18/22] net: stmmac: rk: replace empty set_to_rmii() with supports_rmii
Date: Mon, 26 Jan 2026 11:46:30 +0000 [thread overview]
Message-ID: <E1vkL38-00000005uts-0kDd@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <aXdTi4ViCkhhXvFI@shell.armlinux.org.uk>
Rather than providing a now-empty set_to_rmii() method to indicate
that RMII is supported, switch to setting ops->supports_rmii instead.
Signed-off-by: Russell King (Oracle) <rmk+kernel@armlinux.org.uk>
