* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-0739-79/+39
| | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | U-Boot widely uses error() as a bit noisier variant of printf(). This macro causes name conflict with the following line in include/linux/compiler-gcc.h: # define __compiletime_error(message) __attribute__((error(message))) This prevents us from using __compiletime_error(), and makes it difficult to fully sync BUILD_BUG macros with Linux. (Notice Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().) Let's convert error() into now treewide-available pr_err().

* rockchip: efuse: add (misc) driver for RK3399 non-secure efuse blockPhilipp Tomsich2017-06-073-0/+175
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a simple driver for reading the efuse block of the RK3399. It should be easy enough to add drivers for other devices (e.g. the RK3328, RK3368, etc.) by passing the device details via driver_data. Unlike the kernel driver (using the nvmem subsystem), we don't expose the efuse as multiple named cells, but rather as a linear memory that can be read using misc_read(...). The primary use case (as of today) is the generation of a 'serial#' (and a 'cpuid#') environment variable for the RK3399-Q7 (Puma) system-on-module. Note that this adds a debug-only (i.e. only if DEBUG is defined) command 'rk3399_dump_efuses' that dumps the efuse block's content. N.B.: The name 'rk3399_dump_efuses' was intentionally chosen to include a SoC-name (together with a comment in the function) to remind whoever adds support for additional SoCs that this function currently makes assumptions regarding the size of the fuse-box based on the RK3399. The hope is that the function is adjusted to reflect any changes resulting from generalising the driver for multiple SoCs and is then renamed.

* cros_ec: i2c: Add support for version 3 of the EC protocolMoritz Fischer2017-02-081-0/+84
| | | | | | | | | | | | | Add support for version 3 of the ec protocol. It basically works by stitching some additional header in front (special command code), and having a result and packet_length stitched on for the reply.

* dm: core: Replace of_offset with accessorSimon Glass2017-02-085-11/+11
| | | | | | | | | 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.

* cros_ec: i2c: Group i2c write / read into single transactionMoritz Fischer2017-02-081-11/+15
| | | | | | | | | | | | | Replace dm_i2c_write() / dm_i2c_read() with transaction using struct i2c_msg[2] in order to allow for i2c controller to detect write/read cycle to emit a repeated start condition.
