Merge branch 'fix-rgmii-delays-for-88e1118'
Russell King says:
====================
Fix RGMII delays for 88E1118
This series fixes the RGMII delays for 88E1118 Marvell PHYs, after
a report by Corentin Labbe that the Marvell driver fails to work.
Patch 1 cleans up the paged register accesses in m88e1118_config_init()
and patch 2 adds the RGMII delay configuration.
This comes with an element of risk as existing DT may need to be fixed
for this in a similar way as we have done in the recent past for other
PHY drivers that have misinterpreted the RGMII interface modes.
