Add DT node for USB EHCI function.
Add support for T30-Cardhu, T30-Beaver, T114-Dalmore boards.
Signed-off-by: Jim Lin <ji...@nvidia.com>
---
Changes in v2:
- Remove PLL parameters from dt file
Changes in v3:
- Change VBus GPIO from H.05 to DD.04 for Beaver board.
Changes in v4:
- Change Beaver VBus GPIO to H.05 and value to 0 for polarity to be High.
I don't have Beaver board. So this needs somebody to help test.
Thanks.
- Change Cardhu VBus GPIO value from 3 to 1 because only bit 0 is meaningful.
Changes in v5:
- Move changes on fdtdec.h and fdtdec.c to patch 2/3
- Modify PHY type to hsic for USB2 port
