- check clk_prepare_enable() return code in atmel_flexcom_probe()
- add a commit message to the DT binding patch

- remove MODULE_ALIAS()
- add Acked-by from Boris Brezillon and Alexandre Belloni

- enhance the documentation of DT bindings and change the way the "ranges"
  property is used.
- replace __raw_readl() and __raw_writel() by readl() and writel().
- change the module license to "GPL" for v2 or later
- print the selected flexcom mode after the hardware version

This series of patches a support to the Atmel Flexcom, a wrapper which
integrates an USART, a SPI controller and a TWI controller. Only one
peripheral can be used at a time. The active function is selected though
the Flexcom Mode Register.
