| Amlogic SPI Flash Controller |
| |
| Required properties: |
| - compatible : Should be "amlogic,aml-spi-nor" |
| - reg : Offset and range of the register set for the controller device, different value for different IC. |
| - clocks : Handle to spi-nor flash controller clock, please refer to IC spec. |
| - read-capability : read capability of this flash, please refer to flash spec. 0:normal,1:fast,2:dual read,3:quad read. |
| - spifc-io-width : the io number of spifc on the board. |
| - cs_gpios : we use cs pin as gpio. |
| |
| Example: |
| spifc: spifc@c1108c80 { |
| status = "disabled"; |
| compatible = "amlogic,aml-spi-nor"; |
| reg = <0x0 0xc1108c80 0x0 0x80>; |
| pinctrl-names = "default"; |
| pinctrl-0 = <&spifc_all_pins>; |
| clocks = <&clkc CLKID_CLK81>; |
| clock-names = "core"; |
| spi-nor@0 { |
| compatible = "jedec,spi-nor"; |
| spifc-frequency = <40000000>; |
| read-capability = <2>; |
| spifc-io-width = <2>; |
| cs_gpios = <&gpio BOOT_11 GPIO_ACTIVE_HIGH>; |
| }; |
| }; |
