From mboxrd@z Thu Jan 1 00:00:00 1970 From: Iyappan Subramanian Subject: [PATCH 0/3] Fix backward compatibility of newer firmware with older kernel Date: Fri, 27 Feb 2015 12:08:27 -0800 Message-ID: <1425067710-14879-1-git-send-email-isubramanian@apm.com> Return-path: Sender: netdev-owner@vger.kernel.org To: davem@davemloft.net, netdev@vger.kernel.org, devicetree@vger.kernel.org Cc: linux-arm-kernel@lists.infradead.org, mlangsdo@redhat.com, patches@apm.com, Iyappan Subramanian List-Id: devicetree@vger.kernel.org Kernel 3.17 driver supports only RGMII ethernet interface. Since the Tianocore DT contains same compatibility string for RGMII, SGMII based 1G and XFI based 10G interfaces, crash happens when probe called on SGMII based 1G and XFI based 10G interface. This patch fixes the backward compatibility of the older driver with the newer firmware by making the binding unique so that the older driver won't recognize the non-supported interfaces. --- Iyappan Subramanian (3): Documentation: dts: Update compatible field description for APM X-Gene dtb: change binding name to match with newer firmware DT drivers: net: xgene: fix new firmware backward compatibility with older driver Documentation/devicetree/bindings/net/apm-xgene-enet.txt | 3 ++- arch/arm64/boot/dts/apm/apm-storm.dtsi | 4 ++-- drivers/net/ethernet/apm/xgene/xgene_enet_main.c | 4 ++++ 3 files changed, 8 insertions(+), 3 deletions(-) -- 1.9.1
