Fix some recurring typos: postion->position, *atino->*ation
Some cosmetic typo fixes
SAMA5D44-EK: Cosmetic changes
SAMA5 TWI: Add support for up_i2creset
Update ChangeLog
Add a new interface sam_pio_forceclk() that can be used to force PIO clocking on.  I am afraid I was too conservative with PIO clocking in the initial design; this is the price
Use sam_pio_forceclk() so that we can read the current state of an open-drain output in the TWI reset logic.
Update ChangeLog
SAMA5 TWI: Some restructured needed by up_i2creset.  Also timeout needs to vary with the size of the transfer and if debug is on or not
SAMA5 I2C Reset: More changes... still does not work right
SAMA5 PIO: Fix a typo in Schmitt trigger configuration; Configure pin as a a vanilla input first so that final pin configuration is more read-able (i.e., easier to debug)
Don't have to set SDA high initially in I2C reset because that is done by the pin configuration
Update ChangeLog
add epass3003 driver
Merge branch 'master' into dev
