Subject: MIPS: lantiq: add support for xrx200 firmware depending on soc type
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=276229d2a98975d0cca9637d1dfee6a9876b54c5;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

MIPS: lantiq: add support for xrx200 firmware depending on soc type

VR9 needs different firmware files for the various phy/soc revisions. Some
boards are ship with older and newer SoC revisions. To be able to boot a single
image on all versions we need to define both firmware files inside the
devicetree.
