From 0465d8f830dc40714db6c02e1db28b30206a82f7 Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Fri, 22 May 2020 11:53:31 +0200 Subject: [PATCH] net: phy: at803x: fix PHY ID masks Ever since its first commit 0ca7111a38f05 ("phy: add AT803x driver") the PHY ID mask was set to 0xffffffef. It is unclear to me why this mask was chosen in the first place. Both the AR8031/AR8033 and the AR8035 datasheets mention it is always the given value: - for AR8031/AR8033 its 0x004d/0xd074 - for AR8035 its 0x004d/0xd072 Unfortunately, I don't have a datasheet for the AR8030. Therefore, we leave its PHY ID mask untouched. For the PHYs mentioned before use the handy PHY_ID_MATCH_EXACT() macro. I've tried to contact the author of the initial commit, but received no answer so far. Cc: Matus Ujhelyi Signed-off-by: Michael Walle Signed-off-by: David S.
