Currently I2C device names are assigned dynamically unless they are
instantiated through ACPI, this names are based on adapter_id and
device_address. While device_address will remain constant for a given
device, the adapter_id may vary across different systems and hence,
overall, the device name won't be unique for the same I2C device.

Changes here addresses this problem by introducing an optional device
tree property "dev-name", which will be used to set the device name,
if present, instead of following <adapter_id>-<device_addr> convention.

Manish Varma (2):
  dt-bindings: i2c: add "dev-name" property to assign specific device
    name
  i2c: use "dev-name" device tree property to override device name
