====================
This patch series adds the support for configuring GMII_SEL register
of control module to select the phy mode type and also to configure
the clock source for RMII phy mode whether to use internal clock or
the external clock from the phy itself.

Till now CPSW works as this configuration is done in U-Boot and carried
over to the kernel. But during suspend/resume Control module tends to
lose its configured value for GMII_SEL register in AM33xx PG1.0, so
if CPSW is used in RMII or RGMII mode, on resume cpsw is not working
as GMII_SEL register lost its configuration values.

The initial version of the patch is done by Daniel Mack but as per
Tony's comment he wants it as a seperate driver as it is done in USB
control module. I have created a seperate driver for the same.
