This patchset fixes a regression introduced by
commit e8fcfcd5684a ("net: fec: optimize the clock management to save power")
for ethernet PHYs that are using ENET_OUT as reference clock (on i.MX6 or i.MX28)
Changes vs. v1:
- fixed reference to the commit that introduced the regression.
- dropped patch to use gpiod framework. This should be added later,
after the affected DTBs have been updated to specify the correct
gpio_flags.
Patch overview:
1. cleanup patch to remove redundant NULL checks
2. call fec_reset_phy() after the ENET_OUT clock has been enabled
