From: Andrew Lunn Date: Sat, 15 Feb 2014 12:59:53 +0000 (+0100) Subject: ARM: Kirkwood: convert rd88f6281-setup.c to DT. X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e2eaa339af44;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git ARM: Kirkwood: convert rd88f6281-setup.c to DT. Perform a mechanical translation of rd88f6281-setup.c into DT. Since the hardware differs between the A0 and A1 stepping, two dts files are used, and a .dtsi file for the common parts. The A0 part does not have a "wan" port on the switch and uses PHY address 10 to address the switch. The A1 part does have the "wan" port and uses address 0.
