[PATCH 0/3 v3] Support for Voipac X53-DMM-668 module and Voipac Baseboard

[Rostislav Lisovy]

This patchset adds support for Voipac Baseboard using x53-dmm-668
module (equipped with i.mx53 CPU). More info about the module may
be found at: http://www.voipac.com/#X53-DMM-668

Changes since v2:
* Fix errorhandling in fec_imx
* Define flash controller in DTS
* Use imx53_bbu_internal_nand_register_handler

Applied this series, but dropped this message. The problem with these
kind of messages is that now nearly all i.MX users start seeing it and
wonder if this is something they have to care about.

"phy-reset-duration" property should be handled together with "phy-reset-gpios"-property.
Additionally, the reset level is hardcoded to "0", but should be taken from
2nd cell GPIO DT definition.
I am not sure about 2nd issue, but the first can be implemented very easy.
