1*4882a593SmuzhiyunST SSC binding, for I2C mode operation 2*4882a593Smuzhiyun 3*4882a593SmuzhiyunRequired properties : 4*4882a593Smuzhiyun- compatible : Must be "st,comms-ssc-i2c" or "st,comms-ssc4-i2c" 5*4882a593Smuzhiyun- reg : Offset and length of the register set for the device 6*4882a593Smuzhiyun- interrupts : the interrupt specifier 7*4882a593Smuzhiyun- clock-names: Must contain "ssc". 8*4882a593Smuzhiyun- clocks: Must contain an entry for each name in clock-names. See the common 9*4882a593Smuzhiyun clock bindings. 10*4882a593Smuzhiyun- A pinctrl state named "default" must be defined to set pins in mode of 11*4882a593Smuzhiyun operation for I2C transfer. 12*4882a593Smuzhiyun 13*4882a593SmuzhiyunOptional properties : 14*4882a593Smuzhiyun- clock-frequency : Desired I2C bus clock frequency in Hz. If not specified, 15*4882a593Smuzhiyun the default 100 kHz frequency will be used. As only Normal and Fast modes 16*4882a593Smuzhiyun are supported, possible values are 100000 and 400000. 17*4882a593Smuzhiyun- st,i2c-min-scl-pulse-width-us : The minimum valid SCL pulse width that is 18*4882a593Smuzhiyun allowed through the deglitch circuit. In units of us. 19*4882a593Smuzhiyun- st,i2c-min-sda-pulse-width-us : The minimum valid SDA pulse width that is 20*4882a593Smuzhiyun allowed through the deglitch circuit. In units of us. 21*4882a593Smuzhiyun- A pinctrl state named "idle" could be defined to set pins in idle state 22*4882a593Smuzhiyun when I2C instance is not performing a transfer. 23*4882a593Smuzhiyun- A pinctrl state named "sleep" could be defined to set pins in sleep state 24*4882a593Smuzhiyun when driver enters in suspend. 25*4882a593Smuzhiyun 26*4882a593Smuzhiyun 27*4882a593Smuzhiyun 28*4882a593SmuzhiyunExample : 29*4882a593Smuzhiyun 30*4882a593Smuzhiyuni2c0: i2c@fed40000 { 31*4882a593Smuzhiyun compatible = "st,comms-ssc4-i2c"; 32*4882a593Smuzhiyun reg = <0xfed40000 0x110>; 33*4882a593Smuzhiyun interrupts = <GIC_SPI 187 IRQ_TYPE_LEVEL_HIGH>; 34*4882a593Smuzhiyun clocks = <&clk_s_a0_ls CLK_ICN_REG>; 35*4882a593Smuzhiyun clock-names = "ssc"; 36*4882a593Smuzhiyun clock-frequency = <400000>; 37*4882a593Smuzhiyun pinctrl-names = "default"; 38*4882a593Smuzhiyun pinctrl-0 = <&pinctrl_i2c0_default>; 39*4882a593Smuzhiyun st,i2c-min-scl-pulse-width-us = <0>; 40*4882a593Smuzhiyun st,i2c-min-sda-pulse-width-us = <5>; 41*4882a593Smuzhiyun}; 42
