Gerson Fernando Budke 62ba4723d4 drivers: serial: uart_sam0: Add pinctrl support
Add Atmel sam0 sercom[uart] pinctrl bindings and implements pinctrl at
driver level.  It changes all sam0 boards to use new feature and remove
pinmux driver dependency for sercom[uart].  The samples that require a
binding were update to keep consistency and avoid errors.

Current Sensing
###############

Overview
********
This is a sample app to interface with TI INA219 power monitor.
The values used in the app are for use on Adafruit's breakout board
(https://www.adafruit.com/products/904).

This assumes the slave address is 0x40, where A0 and A1 are all tied to ground.
