As per my comments in the previous patch, the "-r1" entry should be
moved from patch #3 to patch #2.

Also the above line seems to be indented incorrectly.


> +dtb-$(CONFIG_ARCH_QCOM)        += sc7280-herobrine-villager-r0-lte.dtb

For all the sc7180 Chromebook devices the "r0" variants are all sorted
together. Thus the order should end up being:

sc7280-herobrine-villager-r0.dtb
sc7280-herobrine-villager-r0-lte.dtb
sc7280-herobrine-villager-r1.dtb
sc7280-herobrine-villager-r1-lte.dtb

You accidentally dropped the "interconnects" property that was added
by commit a0cdc83fa89b ("arm64: dts: qcom: sc7280: Add proxy
interconnect requirements for modem"). Please put it back.
