75 On those SoCs an alias with the correct I2C bus ID
78 clock-frequency:
81 SCL frequency to use (in Hz). If omitted, 100kHz is used.
83 i2c-scl-rising-time-ns:
86 Number of nanoseconds the SCL signal takes to rise
87 (t(r) in I2C specification). If not specified this is assumed to be
88 the maximum the specification allows(1000 ns for Standard-mode,
89 300 ns for Fast-mode) which might cause slightly slower communication.
91 i2c-scl-falling-time-ns:
94 Number of nanoseconds the SCL signal takes to fall
95 (t(f) in the I2C specification). If not specified this is assumed to
99 i2c-sda-falling-time-ns:
103 (t(f) in the I2C specification). If not specified we will use the SCL
