Suggested-by: Rob Herring <robh@kernel.org> Cc: James Tai <james.tai@realtek.com> Signed-off-by: Andreas Färber <afaerber@suse.de> --- TODO: Add Fixes header once RTD1619 has a stable -rc1 based commit hash. To be followed up by patch unshadowing more RAM from /soc 0x98000000..0xffffffff, once we know the higher RAM windows. v2: New arch/arm64/boot/dts/realtek/rtd1619-mjolnir.dts | 5 +++-- arch/arm64/boot/dts/realtek/rtd16xx.dtsi | 4 +++- 2 files changed, 6 insertions(+), 3 deletions(-) -- 2.16.4
