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: i2c: implement gpio-based I2C deblock

2018-04-11T09:34:27Z

The commit implement a gpio-based software deblocking. The code extract I2C pins description from device tree, switch pins to GPIO mode, toggle SCL until slave release SDA, send I2C stop and switch I2C pins back to I2C mode. Signed-off-by: Alexander Kochetkov

dm: core: Replace of_offset with accessor

2017-02-08T13:12:14Z

At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function. Signed-off-by: Simon Glass

dm: Use dm_scan_fdt_dev() directly where possible

2016-07-27T20:15:54Z

Quite a few places have a bind() method which just calls dm_scan_fdt_dev(). We may as well call dm_scan_fdt_dev() directly. Update the code to do this. Signed-off-by: Simon Glass

dm: Convert users from dm_scan_fdt_node() to dm_scan_fdt_dev()

2016-07-27T20:15:07Z

This new function is more convenient for callers, and handles pre-relocation situations automatically. Signed-off-by: Simon Glass

dm: i2c: Add a function to transfer messages

2015-08-06T02:57:51Z

Sometimes it is useful to be able to transfer a raw I2C message. This happens when the chip address needs to be set manually, or when the data to be sent/received is in another buffer. Add a function to provide access to this. Signed-off-by: Simon Glass Acked-by: Heiko Schocher
