SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

ARM: Tegra210: Add support to common Tegra source/config files

2015-07-28T17:30:20Z

Derived from Tegra124, modified as appropriate during T210 board bringup. Cleaned up debug statements to conserve string space, too. This also adds misc 64-bit changes from Thierry Reding/Stephen Warren. Signed-off-by: Tom Warren Signed-off-by: Thierry Reding Signed-off-by: Stephen Warren

usb: tegra: support device mode

2014-05-14T22:21:17Z

A few changes are made to the Tegra EHCI driver so that it can set everything up for device-mode operation on the first USB controller. This can be used in conjunction with ci_udc.c to operate as a USB device. Detailed changes are: * Rename set_host_mode() to set_up_vbus() since that's really what it does. * Modify set_up_vbus() to know whether it's initializing in host or device mode, and: - Skip the external VBUS check in device mode, since external VBUS is expected in this case. - Disable VBUS output in device mode. * Modify init_phy_mux() to know whether it's initializing in host or device mode, and hence skip setting USBMODE_CM_HC (which enables host mode) in device mode. See the comments in that function for why this is safe w.r.t. the ordering requirements of PHY selection. * Modify init_utmi_usb_controller() to force "b session valid" in device mode, since the HW requires this. This is done in UTMI-specific code, since we only support device mode on the first USB controller, and that controller can only talk to a UTMI PHY. * Enhance ehci_hcd_init() to error-check the requested host-/device-mode vs. the dr_mode (dual-role mode) value present in device tree, and the HW configurations which support device mode. * Enhance ehci_hcd_init() not to skip HW initialization when switching between host and device mode on a controller. This requires remembering which mode the last initialization used. Cc: Jim Lin Cc: Stefan Agner Signed-off-by: Stephen Warren

usb: tegra: combine header file

2014-04-17T15:41:06Z

Combine the Tegra USB header file into one header file for all SoCs. Use ifdef to account for the difference, especially Tegra20 is quite different from newer SoCs. This avoids duplication, mainly for Tegra30 and newer devices. Reviewed-by: Stephen Warren Signed-off-by: Stefan Agner Signed-off-by: Tom Warren

usb: tegra: fix PHY configuration

2014-04-17T15:41:06Z

On Tegra30 and later, the PTS (parallel transceiver select) and STS (serial transceiver select) are part of the HOSTPC1_DEVLC_0 register rather than PORTSC1_0 register. Since the reset configuration usually matches the intended configuration, this error did not show up on Tegra30 devices. Also use the slightly different bit fields of first USB, (USBD) on Tegra20 and move those definitions to the Tegra20 specific header file.

usb: new board-specific USB init interface

2013-10-20T21:42:40Z

This commit unifies board-specific USB initialization implementations under one symbol (usb_board_init), declaration of which is available in usb.h. New API allows selective initialization of USB controllers whenever needed.
