u-boot.git/drivers/i2c, branch v2018.05 Unnamed repository; edit this file 'description' to name the repository. SPDX: Convert all of our single license tags to Linux Kernel style 2018-05-07T13:34:12+00:00 Tom Rini trini@konsulko.com 2018-05-06T21:58:06+00:00 83d290c56fab2d38cd1ab4c4cc7099559c1d5046 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 <trini@konsulko.com> 
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.

i2c: designware: add reset ctrl to driver 2018-04-17T09:39:49+00:00 Dinh Nguyen dinguyen@kernel.org 2018-04-04T22:18:24+00:00 622597dee4f66d5bd7dd5135d770077af04b0349 Add code to look for a reset manager property. Specifically, look for the reset-names of 'i2c'. A reset property is an optional feature, so only print out a warning and do not fail if a reset property is not present. If a reset property is discovered, then use it to deassert, thus bringing the IP out of reset. Signed-off-by: Dinh Nguyen <dinguyen@kernel.org>
