| Every GPIO controller node must have #gpio-cells property defined, |
| this information will be used to translate gpio-specifiers. |
| |
| On CPM1 devices, all ports are using slightly different register layouts. |
| Ports A, C and D are 16bit ports and Ports B and E are 32bit ports. |
| |
| On CPM2 devices, all ports are 32bit ports and use a common register layout. |
| |
| Required properties: |
| - compatible : "fsl,cpm1-pario-bank-a", "fsl,cpm1-pario-bank-b", |
| "fsl,cpm1-pario-bank-c", "fsl,cpm1-pario-bank-d", |
| "fsl,cpm1-pario-bank-e", "fsl,cpm2-pario-bank" |
| - #gpio-cells : Should be two. The first cell is the pin number and the |
| second cell is used to specify optional parameters (currently unused). |
| - gpio-controller : Marks the port as GPIO controller. |
| |
| Example of three SOC GPIO banks defined as gpio-controller nodes: |
| |
| CPM1_PIO_A: gpio-controller@950 { |
| #gpio-cells = <2>; |
| compatible = "fsl,cpm1-pario-bank-a"; |
| reg = <0x950 0x10>; |
| gpio-controller; |
| }; |
| |
| CPM1_PIO_B: gpio-controller@ab8 { |
| #gpio-cells = <2>; |
| compatible = "fsl,cpm1-pario-bank-b"; |
| reg = <0xab8 0x10>; |
| gpio-controller; |
| }; |
| |
| CPM1_PIO_E: gpio-controller@ac8 { |
| #gpio-cells = <2>; |
| compatible = "fsl,cpm1-pario-bank-e"; |
| reg = <0xac8 0x18>; |
| gpio-controller; |
| }; |
