-* Socionext Synquacer HS-SPI bindings
-
-Required Properties:
-- compatible: should be "socionext,synquacer-spi"
-- reg: physical base address of the controller and length of memory mapped
-       region.
-- interrupts: should contain the "spi_rx", "spi_tx" and "spi_fault" interrupts.
-- clocks: core clock iHCLK. Optional rate clock iPCLK (default is iHCLK)
-- clock-names: Shall be "iHCLK" and "iPCLK" respectively
-
-Optional Properties:
-- socionext,use-rtm: boolean, if required to use "retimed clock" for RX
-- socionext,set-aces: boolean, if same active clock edges field to be set.

-
-	spi0: spi@ff110000 {
