Subject: [PATCH v2 0/3] RK356x/Quartz64 Model A SPI

Changes in v2:
 - sort properties in rk356x.dtsi correctly
 - remove pinctrl-1 line from rk356x.dtsi as it refers to
   non-mainline stuff

Original cover letter:

The first patch of this series adds a compatible for rk3568-spi
to the DT bindings.

The second adds the SPI nodes for RK3566 and RK3568 SoCs. The nodes
were lifted from the downstream vendor kernel's devicetree, and were
double-checked for correctness.

The third patch sets up the broken-out SPI pins on the Quartz64
Model A; they use the "m1" set of the pins, not the "m0" set. I
assume the "m" stands for "mux".

I've tested both patches by connecting an MCP2515 SPI CAN bus
controller to the spi pins, which initialised fine.

Regards,
Nicolas Frattaroli
