| 1 | Binding for a type of quad channel digital frequency synthesizer found on | ||
| 2 | certain STMicroelectronics consumer electronics SoC devices. | ||
| 3 | |||
| 4 | This version contains a programmable PLL which can generate up to 216, 432 | ||
| 5 | or 660MHz (from a 30MHz oscillator input) as the input to the digital | ||
| 6 | synthesizers. | ||
| 7 | |||
| 8 | This binding uses the common clock binding[1]. | ||
| 9 | |||
| 10 | [1] Documentation/devicetree/bindings/clock/clock-bindings.txt | ||
| 11 | |||
| 12 | Required properties: | ||
| 13 | - compatible : shall be: | ||
| 14 | "st,stih416-quadfs216", "st,quadfs" | ||
| 15 | "st,stih416-quadfs432", "st,quadfs" | ||
| 16 | "st,stih416-quadfs660-E", "st,quadfs" | ||
| 17 | "st,stih416-quadfs660-F", "st,quadfs" | ||
| 18 | |||
| 19 | - #clock-cells : from common clock binding; shall be set to 1. | ||
| 20 | |||
| 21 | - reg : A Base address and length of the register set. | ||
| 22 | |||
| 23 | - clocks : from common clock binding | ||
| 24 | |||
| 25 | - clock-output-names : From common clock binding. The block has 4 | ||
| 26 | clock outputs but not all of them in a specific instance | ||
| 27 | have to be used in the SoC. If a clock name is left as | ||
| 28 | an empty string then no clock will be created for the | ||
| 29 | output associated with that string index. If fewer than | ||
| 30 | 4 strings are provided then no clocks will be created | ||
| 31 | for the remaining outputs. | ||
| 32 | |||
| 33 | Example: | ||
| 34 | |||
| 35 | CLOCKGEN_E: CLOCKGEN_E { | ||
| 36 | #clock-cells = <1>; | ||
| 37 | compatible = "st,stih416-quadfs660-E", "st,quadfs"; | ||
| 38 | reg = <0xfd3208bc 0xB0>; | ||
| 39 | |||
| 40 | clocks = <&CLK_SYSIN>; | ||
| 41 | clock-output-names = "CLK_M_PIX_MDTP_0", | ||
| 42 | "CLK_M_PIX_MDTP_1", | ||
| 43 | "CLK_M_PIX_MDTP_2", | ||
| 44 | "CLK_M_MPELPC"; | ||
| 45 | }; | ||
