2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>
2017-07-26ARM: uniphier: remove SPL support for ARMv8 SoCsMasahiro Yamada
It has been a while since ARM Trusted Firmware supported UniPhier SoC family. U-Boot SPL was intended as a temporary loader that runs in secure world. It is a maintenance headache to support two different boot mechanisms. Secure firmware is realm of ARM Trusted Firmware and now U-Boot only serves as a non-secure boot loader for UniPhier ARMv8 SoCs.

2017-06-01dm: Fix up inclusion of common.hSimon Glass
It is good practice to include common.h as the first header. This ensures that required features like the DECLARE_GLOBAL_DATA_PTR macro, configuration options and common types are available. Fix up some files which currently don't do this. This is necessary because driver model will soon start using global data and configuration in the dm/read.h header file, included via dm.h. The gd->fdt_blob value will be used to access the device tree and CONFIG options will be used to determine whether to support inline functions in the header file.

2017-06-01dm: Use dm.h header when driver mode is usedSimon Glass
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>
2017-02-23pinctrl: uniphier: support pin configurationMasahiro Yamada
Support the following DT properties: "bias-disable" "bias-pull-up" "bias-pull-down" "bias-pull-pin-default" "input-enable" "input-disable" My main motivation is to support pull up/down biasing. For Pro5 and later SoCs, the pupdctrl register number is the same as the pinmux number, so this feature can be supported without having big pin tables.

2016-09-14pinctrl: uniphier: add System Bus pin-mux settingsMasahiro Yamada
This is needed to get access to UniPhier System Bus (external bus). Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-07-24ARM: uniphier: use (devm_)ioremap() instead of map_sysmem()Masahiro Yamada
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>

2016-07-02pinctrl: uniphier: avoid building unneeded pin-mux tables for SPLMasahiro Yamada
SPL does not use all of the devices, so we can save some memory footprint. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-07-02pinctrl: uniphier: support pin configuration for dedicated pinsMasahiro Yamada
PH1-LD4 and PH1-sLD8 SoCs have pins that support pin configuration (pin biasing, drive strength control), but not pin-muxing. Allow to fill the mux value table with -1 for those pins; pins with mux value -1 will be skipped in the pin-mux set function. The mux value type should be changed from "unsigned" to "int" in order to accommodate -1 as a special case.

2016-07-02pinctrl: uniphier: split pinctrl driver for PH1-LD11 and PH1-LD20Masahiro Yamada
PH1-LD11 and PH1-LD20 have much pin controlling in common, so I added a single driver shared between them in the initial commit. However, the Ethernet pin-mux settings I am going to add are different with each other, and they may diverge more as the progress of development. Split it into two dedicated drivers.
