[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.

- * The values of DEBOUNCE_A and DEBOUNCE_B are calculated as follows:
- * 0xffff -> No debouncing at all
- * <n> ms = <n> *1000 / (1/19.2MHz) / 4

- * So to program a 1 ms debounce for BIAS_DEBOUNCE_A, we have:
- * BIAS_DEBOUNCE_A[15:0] = 1000 * 19.2 / 4 = 4800 = 0x12c0
- *
- * We need to use only DebounceA for BOOTROM. We don't need the DebounceB
