[U-Boot] [PATCH 01/14] net: davinci_emac: convert to using the driver model
Bartosz Golaszewski
brgl at bgdev.pl
Tue Jul 9 07:55:16 UTC 2019
From: Bartosz Golaszewski <bgolaszewski at baylibre.com>
Now that we removed all legacy boards selecting TI_EMAC we can
completely convert the driver code to using the driver model.
This patch also updates all remaining users of davinci_emac.
