The 5P35023 device is a three PLL 16a03d23f8SBiju Das architecture design, and each PLL is individually programmable 17a03d23f8SBiju Das and allowing for up to 6 unique frequency outputs. 18a03d23f8SBiju Das 19a03d23f8SBiju Das An internal OTP memory allows the user to store the configuration 20a03d23f8SBiju Das in the device. After power up, the user can change the device register 21a03d23f8SBiju Das settings through the I2C interface when I2C mode is selected. 22a03d23f8SBiju Das 23a03d23f8SBiju Das The driver can read a full register map from the DT, and will use that 24a03d23f8SBiju Das register map to initialize the attached part (via I2C) when the system 25a03d23f8SBiju Das boots. Any configuration not supported by the common clock framework 26a03d23f8SBiju Das must be done via the full register map, including optimized settings. 27a03d23f8SBiju Das 28a03d23f8SBiju Das Link to datasheet: 29a03d23f8SBiju Das https://www.renesas.com/us/en/products/clocks-timing/clock-generation/programmable-clocks/5p35023-versaclock-3s-programmable-clock-generator 30a03d23f8SBiju Das 31a03d23f8SBiju Dasproperties: 32a03d23f8SBiju Das compatible: 33a03d23f8SBiju Das enum: 34*626b7773SClaudiu Beznea - renesas,5l35023 35a03d23f8SBiju Das - renesas,5p35023 36a03d23f8SBiju Das 37a03d23f8SBiju Das reg: 38a03d23f8SBiju Das maxItems: 1 39a03d23f8SBiju Das 40a03d23f8SBiju Das '#clock-cells': 411aa2a9f2SBiju Das description: 421aa2a9f2SBiju Das The index in the assigned-clocks is mapped to the output clock as below 431aa2a9f2SBiju Das 0 - REF, 1 - SE1, 2 - SE2, 3 - SE3, 4 - DIFF1, 5 - DIFF2. 44a03d23f8SBiju Das const: 1 45a03d23f8SBiju Das 46a03d23f8SBiju Das clocks: 47a03d23f8SBiju Das maxItems: 1 48a03d23f8SBiju Das 49a03d23f8SBiju Das renesas,settings: 50a03d23f8SBiju Das description: Optional, complete register map of the device. 51a03d23f8SBiju Das Optimized settings for the device must be provided in full 52a03d23f8SBiju Das and are written during initialization. 53a03d23f8SBiju Das $ref: /schemas/types.yaml#/definitions/uint8-array 54a03d23f8SBiju Das maxItems: 37 55a03d23f8SBiju Das 56a03d23f8SBiju Dasrequired: 57a03d23f8SBiju Das - compatible 58a03d23f8SBiju Das - reg 59a03d23f8SBiju Das - '#clock-cells' 60a03d23f8SBiju Das - clocks 61a03d23f8SBiju Das 62a03d23f8SBiju DasadditionalProperties: false 63a03d23f8SBiju Das 64a03d23f8SBiju Dasexamples: 65a03d23f8SBiju Das - | 66a03d23f8SBiju Das i2c { 67a03d23f8SBiju Das #address-cells = <1>; 68a03d23f8SBiju Das #size-cells = <0>; 69a03d23f8SBiju Das 70a03d23f8SBiju Das versa3: clock-generator@68 { 71a03d23f8SBiju Das compatible = "renesas,5p35023"; 72a03d23f8SBiju Das reg = <0x68>; 73a03d23f8SBiju Das #clock-cells = <1>; 74a03d23f8SBiju Das 751aa2a9f2SBiju Das clocks = <&x1>; 76a03d23f8SBiju Das 77a03d23f8SBiju Das renesas,settings = [ 78a03d23f8SBiju Das 80 00 11 19 4c 02 23 7f 83 19 08 a9 5f 25 24 bf 79a03d23f8SBiju Das 00 14 7a e1 00 00 00 00 01 55 59 bb 3f 30 90 b6 80a03d23f8SBiju Das 80 b0 45 c4 95 81a03d23f8SBiju Das ]; 82a03d23f8SBiju Das 83a03d23f8SBiju Das assigned-clocks = <&versa3 0>, <&versa3 1>, 84a03d23f8SBiju Das <&versa3 2>, <&versa3 3>, 85a03d23f8SBiju Das <&versa3 4>, <&versa3 5>; 861aa2a9f2SBiju Das assigned-clock-rates = <24000000>, <11289600>, 871aa2a9f2SBiju Das <11289600>, <12000000>, 881aa2a9f2SBiju Das <25000000>, <12288000>; 89a03d23f8SBiju Das }; 90a03d23f8SBiju Das }; 91
