1 | Device-Tree bindings for Atmel's HLCDC (High LCD Controller) MFD driver |
| 2 | ||
| 3 | Required properties: | |
| 4 | - compatible: value should be one of the following: | |
| d9c93f5d BB |
5 | "atmel,at91sam9n12-hlcdc" |
| 6 | "atmel,at91sam9x5-hlcdc" | |
| 7 | "atmel,sama5d2-hlcdc" | |
| 590b7795 | 8 | "atmel,sama5d3-hlcdc" |
| d9c93f5d | 9 | "atmel,sama5d4-hlcdc" |
| 590b7795 BB |
10 | - reg: base address and size of the HLCDC device registers. |
| 11 | - clock-names: the name of the 3 clocks requested by the HLCDC device. | |
| 12 | Should contain "periph_clk", "sys_clk" and "slow_clk". | |
| 13 | - clocks: should contain the 3 clocks requested by the HLCDC device. | |
| 14 | - interrupts: should contain the description of the HLCDC interrupt line | |
| 15 | ||
| 16 | The HLCDC IP exposes two subdevices: | |
| 17 | - a PWM chip: see ../pwm/atmel-hlcdc-pwm.txt | |
| efdbd734 | 18 | - a Display Controller: see ../display/atmel-hlcdc-dc.txt |
