| Binding for a type of STMicroelectronics clock crossbar (VCC). |
| |
| The crossbar can take up to 4 input clocks and control up to 16 |
| output clocks. Not all inputs or outputs have to be in use in a |
| particular instantiation. Each output can be individually enabled, |
| select any of the input clocks and apply a divide (by 1,2,4 or 8) to |
| that selected clock. |
| |
| This binding uses the common clock binding[1]. |

| |
| Required properties: |
| |
| - compatible : shall be: |
| "st,stih416-clkgenc", "st,vcc" |
| "st,stih416-clkgenf", "st,vcc" |
| |
| - #clock-cells : from common clock binding; shall be set to 1. |
| |
| - reg : A Base address and length of the register set. |
| |
| - clocks : from common clock binding |
| |
| - clock-output-names : From common clock binding. The block has 16 |
| clock outputs but not all of them in a specific instance |
| have to be used in the SoC. If a clock name is left as |
| an empty string then no clock will be created for the |
| output associated with that string index. If fewer than |
| 16 strings are provided then no clocks will be created |
| for the remaining outputs. |
| |
| Example: |
| |
| CLOCKGEN_C_VCC: CLOCKGEN_C_VCC { |
| #clock-cells = <1>; |
| compatible = "st,stih416-clkgenc", "st,clkgen-vcc"; |
| reg = <0xfe8308ac 12>; |
| |
| clocks = <&CLK_S_VCC_HD>, <&CLOCKGEN_C 1>, |
| <&CLK_S_TMDS_FROMPHY>, <&CLOCKGEN_C 2>; |
| |
| clock-output-names = |
| "CLK_S_PIX_HDMI", "CLK_S_PIX_DVO", |
| "CLK_S_OUT_DVO", "CLK_S_PIX_HD", |
| "CLK_S_HDDAC", "CLK_S_DENC", |
| "CLK_S_SDDAC", "CLK_S_PIX_MAIN", |
