Cyrille actually placed it as the v1 changelog below...

I think that Rob was okay with the DT binding: "A few comments, but in
general looks fine." and it may not be important to tack Rob for
addition of his formal tag...

Or maybe this message can act as a "ping" for Rob...

We wait one or two days before Cyrille re-send the series. We are
looking forward to using this driver in Linux-next soon.

Bye,

>> v8:

>> - 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"

>> - 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
