From b3f0c79cba2060c1af37b32d60eff8598391519e Mon Sep 17 00:00:00 2001 From: Igor Russkikh Date: Thu, 30 Apr 2020 11:04:39 +0300 Subject: net: atlantic: A2 hw_ops skeleton This patch adds basic hw_ops layout for A2. Actual implementation will be added in the follow-up patches. Signed-off-by: Igor Russkikh Signed-off-by: Mark Starovoytov Signed-off-by: David S.
