* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-2/+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>

* gpio: uniphier: rework single device node modelMasahiro Yamada2017-10-151-51/+89
| | | | | | | | | | | | | | | | First, I implemented this driver as per-bank model, but it was a design mistake. - There are 31 banks in the maximum case. It is painful to add so many nodes to DT. - The IRQ control registers are shared between banks. Per-bank design is a problem for Linux. The counterpart for Linux turned around to the single node model. Rework based on the driver for Linux. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* dm: Rename dev_addr..() functionsSimon Glass2017-06-011-1/+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.

* dm: Use dm.h header when driver mode is usedSimon Glass2017-06-011-1/+1
| | | | | | | | This header includes things that are needed to make driver build. Adjust existing users to include that always, even if other dm/ includes are present Signed-off-by: Simon Glass <sjg@chromium.org>
* treewide: replace #include <asm/errno.h> with <linux/errno.h>Masahiro Yamada2016-09-231-1/+1
| | | | | | | | | | | Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have the same content. (both just wrap <asm-generic/errno.h>) Replace all include directives for <asm/errno.h> with <linux/errno.h>.

* ARM: uniphier: use (devm_)ioremap() instead of map_sysmem()Masahiro Yamada2016-07-241-13/+3
| | | | | | | | This does not have much impact on behavior, but makes code look more more like Linux. The use of devm_ioremap() often helps to delete .remove callbacks entirely. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* gpio: uniphier: use devm_get_addr() to get base addressMasahiro Yamada2016-04-011-5/+3
| | | | | | | | | Currently, fdtdec_get_addr_size() does not support the address translation, so it cannot handle device trees with non-straight "ranges" properties. (This would be a problem with DTS for UniPhier ARMv8 SoCs.) Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
