[U-Boot] [PATCH 2/3] ARM: Tegra: USB: Add driver support for Tegra30/Tegra114

Jim Lin jilin at nvidia.com
Mon Apr 29 11:21:14 CEST 2013


Tegra30 and Tegra114 are compatible except
1. T30 takes 55 ms to finish Port Reset. T114 takes
   50 ms.
2. PLL parameters

Tested on Tegra20 Harmony/Seaboard, Tegra30 Cardhu, and Tegra114 Dalmore
platforms. All works well.
