0001 Binding for Silicon Labs 570, 571, 598 and 599 programmable
0002 I2C clock generators.
0003 
0004 Reference
0005 This binding uses the common clock binding[1]. Details about the devices can be
0006 found in the data sheets[2][3].

0013 
0014 Required properties:
0015  - compatible: Shall be one of "silabs,si570", "silabs,si571",
0016                                "silabs,si598", "silabs,si599"
0017  - reg: I2C device address.
0018  - #clock-cells: From common clock bindings: Shall be 0.
0019  - factory-fout: Factory set default frequency. This frequency is part specific.
0020                  The correct frequency for the part used has to be provided in
0021                  order to generate the correct output frequencies. For more
0022                  details, please refer to the data sheet.
0023  - temperature-stability: Temperature stability of the device in PPM. Should be
0024                           one of: 7, 20, 50 or 100.
0025 
0026 Optional properties:
0027  - clock-output-names: From common clock bindings. Recommended to be "si570".
0028  - clock-frequency: Output frequency to generate. This defines the output
0029                     frequency set during boot. It can be reprogrammed during
0030                     runtime through the common clock framework.
0031  - silabs,skip-recall: Do not perform NVM->RAM recall operation. It will rely
0032                        on hardware loading of RAM from NVM at power on.
0033 
0034 Example:
0035         si570: clock-generator@5d {
0036                 #clock-cells = <0>;
0037                 compatible = "silabs,si570";
0038                 temperature-stability = <50>;
0039                 reg = <0x5d>;
0040                 factory-fout = <156250000>;
0041         };
