2020-12-13dm: treewide: Rename ofdata_to_platdata() to of_to_plat()Simon Glass
This name is far too long. Rename it to remove the 'data' bits. This makes it consistent with the platdata->plat rename. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename 'platdata' variables to just 'plat'Simon Glass
We use 'priv' for private data but often use 'platdata' for platform data. We can't really use 'pdata' since that is ambiguous (it could mean private or platform data). Rename some of the latter variables to end with 'plat' for consistency. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-12-13dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass
This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

Move this header out of the common header. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

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>

2017-06-07regulator: pwm: Fix handling of missing init voltageMark Kettenis
Since priv->init_voltage is an unsigned integer it can never be negative. So the current code fails to detect a missing 'regulator-init-microvolt' property and instead misconfigures the PWM device. Fix this by making the relevant members of 'struct pwm_regulator_info' signed integers. Signed-off-by: Mark Kettenis <kettenis@openbsd.org>
2017-05-10power: regulator: pwm: support pwm polarity settingKever Yang
The latest kernel PWM drivers enable the polarity settings. When system run from U-Boot to kerenl, if there are differences in polarity set or duty cycle, the PMW will re-init: close -> set polarity and duty cycle -> enable the PWM. The power supply controled by pwm regulator may have voltage shaking, which lead to the system not stable.

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.
