With addition of PXA910 family of devices, the TWSI module supports
new feature which allows us to adjust SCLK. i2c-pxa driver takes input
configuration in nsec and converts it to respective bit-fields,
- i2c-sclk-low-time-ns : SCLK low time (tlow)
This property is used along with mode selection.
- i2c-sclk-high-time-ns : SCLK high time (thigh)
- i2c-start-hold-time-ns : Used in case of high speed mode for start bit
hold/setup wait counter.
- i2c-stop-hold-time-ns : Used in case of high speed mode for stop bit
hold/setup wait counter.
- i2c-sda-hold-time-ns : Used to calculate hold/setup wait counter for
standard and fast mode.
Again, these should have a mrvl prefix..very specific to this PXA
controller.
