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>
2018-03-05libfdt: move headers to <linux/libfdt.h> and <linux/libfdt_env.h>Masahiro Yamada
Thomas reported U-Boot failed to build host tools if libfdt-devel package is installed because tools include libfdt headers from /usr/include/ instead of using internal ones. This commit moves the header code: include/libfdt.h -> include/linux/libfdt.h include/libfdt_env.h -> include/linux/libfdt_env.h and replaces include directives: #include <libfdt.h> -> #include <linux/libfdt.h> #include <libfdt_env.h> -> #include <linux/libfdt_env.h> Reported-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2017-06-01dm: gpio: Add live tree supportSimon Glass
Add support for requesting GPIOs with a live device tree. This involves adjusting the function signature for the legacy function gpio_request_by_name_nodev(), so fix up all callers.

2017-02-08dm: core: Replace of_offset with accessorSimon Glass
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.

2017-01-23mmc: sdhci: Distinguish between base clock and maximum peripheral frequencyStefan Herbrechtsmeier
The sdhci controller assumes that the base clock frequency is fully supported by the peripheral and doesn't support hardware limitations. The Linux kernel distinguishes between base clock (max_clk) of the host controller and maximum frequency (f_max) of the card interface. Use the same differentiation and allow the platform to constrain the peripheral interface. Signed-off-by: Stefan Herbrechtsmeier <stefan.herbrechtsmeier@weidmueller.com>

2015-11-02s5p sdhci: call pinmux for card's gpio pins before use themPrzemyslaw Marczak
The SD card detection depends on checking one pin state. But the pin was configured after card was detected, which is wrong. This commit fixes this, by moving call to pinmux before use the pin.

2015-08-18of: clean up OF_CONTROL ifdef conditionalsMasahiro Yamada
We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear away the ugly logic in include/fdtdec.h: #ifdef CONFIG_OF_CONTROL # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL) # define OF_CONTROL 0 # else # define OF_CONTROL 1 # endif #else # define OF_CONTROL 0 #endif Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for SPL. Also, we no longer have to cancel CONFIG_OF_CONTROL in include/config_uncmd_spl.h and scripts/Makefile.spl.
