| Macronix SPI controller Device Tree Bindings |
| -------------------------------------------- |
| |
| Required properties: |
| - compatible: should be "mxicy,mx25f0a-spi" |
| - #address-cells: should be 1 |
| - #size-cells: should be 0 |
| - reg: should contain 2 entries, one for the registers and one for the direct |
| mapping area |
| - reg-names: should contain "regs" and "dirmap" |
| - interrupts: interrupt line connected to the SPI controller |
| - clock-names: should contain "ps_clk", "send_clk" and "send_dly_clk" |
| - clocks: should contain 3 entries for the "ps_clk", "send_clk" and |
| "send_dly_clk" clocks |
| |
| Example: |
| |
| spi@43c30000 { |
| compatible = "mxicy,mx25f0a-spi"; |
| reg = <0x43c30000 0x10000>, <0xa0000000 0x20000000>; |
| reg-names = "regs", "dirmap"; |
| clocks = <&clkwizard 0>, <&clkwizard 1>, <&clkc 18>; |
| clock-names = "send_clk", "send_dly_clk", "ps_clk"; |
| #address-cells = <1>; |
| #size-cells = <0>; |
| |
| flash@0 { |
| compatible = "jedec,spi-nor"; |
| reg = <0>; |
| spi-max-frequency = <25000000>; |
| spi-tx-bus-width = <4>; |
| spi-rx-bus-width = <4>; |
| }; |
| }; |
