2018-10-29fsl/usb: Workaround for USB erratum-A005275Chris Packham1-0/+7
Workaround makes FS as default mode on all affected socs. Add support to check erratum-A005275 validity for an soc. This info is required to determine whether a given soc is affected by this erratum. Add quirk for this erratum "has_fsl_erratum_a005275" . This quirk is used to enable workaround for the errata Force FS mode as default by: - making EPS as FS - setting PFSC bit to disable HS chirping This workaround can be disabled by mentioning "no_erratum_a005275" in hwconfig string Signed-off-by: Chris Packham <judge.packham@gmail.com> Reviewed-by: York Sun <york.sun@nxp.com>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
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>

2017-08-16env: Rename getenv/_f() to env_get()Simon Glass1-1/+1
We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also.

2017-06-01dm: Rename dev_addr..() functionsSimon Glass1-1/+1
These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.

2017-02-08dm: core: Replace of_offset with accessorSimon Glass1-1/+1
