5 - compatible : should be "snps,designware-i2c"
6 - reg : Offset and length of the register set for the device
7 - interrupts : <IRQ> where IRQ is the interrupt number.
11 - clock-frequency : desired I2C bus clock frequency in Hz.
14 - i2c-sda-hold-time-ns : should contain the SDA hold time in nanoseconds.
17 - i2c-scl-falling-time-ns : should contain the SCL falling time in nanoseconds.
18 This value which is by default 300ns is used to compute the tLOW period.
20 - i2c-sda-falling-time-ns : should contain the SDA falling time in nanoseconds.
21 This value which is by default 300ns is used to compute the tHIGH period.
