[PATCH 0/3] Ensure Low period of SCL is correct

[Lucas Tanure <tanure@linux.com>]

The default duty cycle of 33% is less than the required
by the I2C specs for the LOW period of the SCL clock.

So, for 100Khz or less, use 50%H/50%L duty cycle, and
for the clock above 100Khz, use 40%H/60%L duty cycle.
That ensures the low period of SCL is always more than
the minimum required by the specs at any given frequency.

Lucas Tanure (3):
  i2c: meson: Use _SHIFT and _MASK for register definitions
  i2c: meson: Use 50% duty cycle for I2C clock
  i2c: meson: Remove meson_i2c_data
