| Binding for a Clockgen hardware block found on |
| certain STMicroelectronics consumer electronics SoC devices. |
| |
| A Clockgen node can contain pll, diviser or multiplexer nodes. |
| |
| We will find only the base address of the Clockgen, this base |
| address is common of all subnode. |
| |
| clockgen_node { |
| reg = <>; |
| |
| pll_node { |
| ... |
| }; |
| |
| prediv_node { |
| ... |
| }; |
| |
| divmux_node { |
| ... |
| }; |
| |
| quadfs_node { |
| ... |
| }; |
| |
| mux_node { |

| }; |
| |
| vcc_node { |
| ... |
| }; |
| |
| flexgen_node { |
| ... |
| }; |
| ... |
| }; |
| |
| This binding uses the common clock binding[1]. |
| Each subnode should use the binding described in [2]..[7] |
