Oops, I forgot to attach the changelog. Sorry for the inconvenience and
please refer to this,
- dt-binding changes
- relicense binding headers as GPL-2.0-only OR MIT
- use gapless integers starting from 0 for binding IDs
- make input clocks essential, add corresponding description
- rename the input clock that is generated by phy module as "gmac0"
- style fixes
- driver changes
- format in the common Rockchip driver style
- drop initializing code of the reset controller, as it'll not be
supported in this series
