[PATCH v3 5/5] dts: r64: add sata- and asm_sel nodes

Frank Wunderlich linux at fw-web.de
Thu Aug 13 10:20:48 CEST 2020


From: Frank Wunderlich <frank-w at public-files.de>

asm_sel is for switching between sata and pcie mode
on r64 there is GPIO90 connected to ASM1480 which
switches RX/TX pairs to PCIe/SATA connector
output-low means sata-controller is active

with 2020-10 now reg is also needed for the phy itself
