This patch adds the support for APM Merlin board. The Merlin board is based on the APM X-Gene Shadowcat SoC. This DTS enables PMU, SATA and Serial. Signed-off-by: Feng Kan <fkan@apm.com> --- V1 Change: - add memreserve for spintable. - remove clkfreq attribute - update spin location, although it is done by bootloader. - remove msi reg entry - add chosen for stdout path arch/arm64/boot/dts/apm/apm-merlin.dts | 41 ++++++++ arch/arm64/boot/dts/apm/apm-shadowcat.dtsi | 154 +++++++++++++++++++++++++++++ 2 files changed, 195 insertions(+) create mode 100644 arch/arm64/boot/dts/apm/apm-merlin.dts create mode 100644 arch/arm64/boot/dts/apm/apm-shadowcat.dtsi
