Tegra30 and Tegra114 are compatible except PLL parameters. Tested on Tegra30 Cardhu, and Tegra114 Dalmore platforms. All works well. Signed-off-by: Jim Lin <jilin@nvidia.com> --- Changes in v2: - Move common definitions into arch-tegra/usb.h and chip specific definitions into arch-tegraXX(X)/usb.h - In ehci-tegra.c, add PLL parameters for Tegra30 and Tegra114. - In ehci-tegra.c, use the port pointed by "nvidia,has-legacy-mode" to know whether we do special handling on Port Reset. - Remove some irrelevant whitespace changes. - Use if-else, instead of goto in ehci-tegra.c init_utmi_usb_controller(). - Use original coding for PTS_MASK in ehci-tegra.c init_utmi_usb_controller(). Reason is that these bits are read-only on Tegra20. Don't need special handling between USB1 and USB3 ports. - Use if-else, instead of goto in ehci-tegra.c board_usb_init().
