This series contains set of code clean up and optimizations for TI networking drivers.
Patch 1 - Adds drivers/net/ti/ folder and moves all TI's networking code
in this folder.
Patches 2,3 - keystone2 clean up
Patch 5 - introduces common TI MDIO support library as existing TI SoCs network
HW IPs have similar MDIO implementation.
Patches 6-7 - conversation of TI CPSW and keystone_net drivers to use common
TI MDIO support library
tested dhcp and kernel boot on:
- k2e/g/hk/l evms
- am437x-gpevm and AM5748 IDK
changes in v3:
- patch 5 comments applied
changes in v2:
- patch 5 comments fixed: use wait_for_bit, snprintf, mdelay, mdio_free
v2: https://patchwork.ozlabs.org/cover/991649/
v1: https://patchwork.ozlabs.org/cover/989449/
TODO: TODO: As per code and documentation davinci_emac.c seems also can be
re-worked to use common TI MDIO support library and network PHYs framework.
Unfortunately, I have no HW to work with.
Grygorii Strashko (7):
driver: net: consolidate ti's code in separate folder
configs: net: convert DRIVER_TI_KEYSTONE_NET kconfig
drivers: net: keystone_net: drop non dm code
driver: net: ti: cpsw: update to use SPDX identifier
driver: net: ti: introduce common mdio support library
driver: net: ti: cpsw: switch to use common mdio lib
driver: net: ti: keystone_net: switch to use common mdio lib
