[PATCH 0/2] Add Radxa ROCK 5B+ defconfig

[Bryan Hinton]

Thanks, I did see that. When I pulled mainline master, I only saw the 5b defconfig and dtsi includes in arch/arm/dts. The plus dts file was in dts/upstream/src/arm64/rockchip and appeared to mirror the dts configuration in Linux mainline arch/arm64/boot/dts/rockchip for the 5b+.  I tried the dts configuration a few different ways and reduced it to just including the 5b config per Tom in the patches just sent.
I’m doing other testing on the board related to memory and timing, and hope to submit some more mainline contributions in the future.

Which TPL do you use for testing the rock5b+?
