[Lee Jones]

Patch set description?

Once Rob is satisfied, please re-submit this set with Nicolas' Acks
and I will re-review.

> ChangeLog
> 
> v9:
> - go back to v5 (use the new "atmel,flexcom-mode" DT property).
> - fix the name of the spi node in the DT example: from spi at f8034400 to
>   spi at 400
> - align the fields of the struct platform_driver atmel_flexcom_driver as
>   suggested by Lee Jones.
> 
> v8:
> - fix the name of the spi node in the DT example: from spi at f8034400 to
>   spi at 2,0
> - use the return code of op_property_read_u32_index() instead of -EINVAL
>   to report error.
> - add Acked-by from Nicolas Ferre
> 
> v7:
> - read the operating mode from the very first u32 of the reg property from
>   the first available child node (should be unique).
> - update the DT bindings documentation accordingly.
> 
> v6:
> - select the operating mode according to the "compatible" DT property of
>   the first available child node (should be unique).
> - remove the "atmel,flexcom-mode" DT property so the need of a header file
>   defining macros for the possible values of this deprecated property.
> 
> v5:
> - create a header file containing macros used by DT bindings
> - use numeric constants instead of strings to select the Flexcom mode
> - change the license to "GPL v2"
> - update the DT binding documentation to make it more readable and add
>   references to USART, SPI and I2C DT binding documentations. remove the
>   useless label in the Example section.
> - change the register prefix from FX_ to FLEX_ to match the Flexcom
>   programmer datasheet.
> - rename some variables to make them more understandable.
> 
> v4:
> - check clk_prepare_enable() return code in atmel_flexcom_probe()
> - add a commit message to the DT binding patch
> 
> v3:
> - remove MODULE_ALIAS()
> - add Acked-by from Boris Brezillon and Alexandre Belloni
> 
> v2:
> - 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
> 
> v1:
> 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.

> Cyrille Pitchen (3):
>   mfd: atmel-flexcom: create include file with macros used by DT
>     bindings
>   mfd: devicetree: add bindings for Atmel Flexcom
>   mfd: atmel-flexcom: add a driver for Atmel Flexible Serial
