PACKAGE RaspberryPi4 IS

  -- The Raspberry Pi 4 has additional I2C bus controllers, which can be
  -- enabled by device tree overlays i2c3, i2c4, i2c5, or i2c6.

  I2C3   : CONSTANT Device.Designator := (0,  3);  -- GPIO2/GPIO3   or GPIO4/GPIO5
  I2C4   : CONSTANT Device.Designator := (0,  4);  -- GPIO6/GPIO7   or GPIO8/GPIO9
  I2C5   : CONSTANT Device.Designator := (0,  5);  -- GPIO10/GPIO11 or GPIO12/GPIO13
  I2C6   : CONSTANT Device.Designator := (0,  6);  -- GPIO0/GPIO1   or GPIO22/GPIO23
