The Banana Pi M64 board is a typical single board computer based on the
Allwinner A64 SoC. Aside from the usual peripherals it features eMMC
storage, which is connected to the 8-bit capable SDHC2 controller.
Also it has a soldered WiFi/Bluetooth chip, so we enable UART1 and SDHC1
as those two interfaces are connected to it.

And the nodes too.

Please use a define here.

Allwinner recommends to use 30mA, have you tested it?

This is the default now.

For other nodes, we've been creating another node for the cts and rts
signals, and reference both nodes in the pinctrl properties. It allows
to avoid duplication.

Please sort it by alphabetical order. And it should be in a separate
patch.
