usb: s/CONFIG_DM_USB/CONFIG_IS_ENABLED(DM_USB)/

2018-11-26T20:19:03Z

This allows to disable the USB driver model in SPL because it checks the CONFIG_SPL_DM_USB variable for SPL builds. Nothing changes for regular non-SPL builds. Signed-off-by: Sven Schwermer

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

dm: usb: emul: Drop usb_emul_reset()

2017-10-01T14:32:51Z

With the root hub unbinding in usb_stop(), there is no need to do a Sandbox-specific reset operation. usb_emul_reset() is no longer used anywhere, drop it. Signed-off-by: Bin Meng

usb: emul: Expose find_descriptor() as a public API

2017-10-01T14:32:51Z

This can be useful outside of the sandbox usb emulation uclass driver. Expose it as a public API with a proper prefix (usb_emul_). Signed-off-by: Bin Meng

usb: sandbox: Fix emulator device select logic in usb_emul_find_devnum()

2017-10-01T14:32:50Z

Current emulator select logic in usb_emul_find_devnum() is to test the USB address. The USB address of the device being enumerated is initialized to zero at the beginning of the enumeration process in usb_setup_device(). At this point, the saved USB address in the platform data has not been assigned to any valid USB address either. This means: the logic will select an emulator device according to its sequence of declaring order in the device tree. Take test.dts for example, flash-stick@0 will be selected before flash-stick@1. But unfortunately such logic is wrong. In fact USB devices show up in a random order during the enumeration which means usb_emul_find_devnum() may be called on port 3 for keyb@3 before on port 0 for flash-stick@0. To fix this, we introduce a new emulator uclass specific platdata to store the USB device's port number on its parent hub, and update the logic to test the port number instead.

dm: usb: Add a new USB controller operation 'get_max_xfer_size'

The HCD may have limitation on the maximum bytes to be transferred in a USB transfer. USB class driver needs to be aware of this. Signed-off-by: Bin Meng

dm: usb: Add a new USB controller operation 'update_hub_device'

2017-07-28T21:34:35Z

For USB host controllers like xHC, its internal representation of hub needs to be updated after the hub descriptor is fetched. This adds a new op that does this. Signed-off-by: Bin Meng Reviewed-by: Simon Glass

usb: hub: Parse and save TT details from device descriptor

2017-07-28T21:34:34Z

A high speed hub has a special responsibility to handle full speed/ low speed devices connected on downstream ports. In this case, the hub must isolate the high speed signaling environment from the full speed/low speed signaling environment with the help of Transaction Translator (TT). TT details are provided by hub descriptors and we parse and save it to hub uclass_priv for later use. Signed-off-by: Bin Meng Reviewed-by: Simon Glass
