Subject: [PATCH] sunxi: Fix gmac not working due to cpu_eth_init no longer
|
|
being called
|
|
|
|
cpu_eth_init is no longer called for dm enabled eth drivers, this
|
|
was causing the sunxi gmac eth controller to no longer work in u-boot.
|
|
|
|
This commit fixes this by calling the clock, reset and pinmux setup
|
|
function from s_init() and enabling the phy power pin (if any) from
|
|
board_init().
|
|
|
|
The enabling of phy power cannot be done from s_init because it uses dm
|
|
and dm is not ready yet at this point.
|
|
|
|
Note that the mdelay is dropped as the phy gets enabled much earlier
|
|
now, so it is no longer needed.
