* common: Drop asm/global_data.h from common headerWIP/2021-02-02-drop-asm_global_data-when-unusedSimon Glass2021-02-021-0/+1
| | | | | | | | | | | | Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

* | dm: Drop uses of dev_set_of_offset()Simon Glass2020-12-131-1/+0
| | | | | | | | | | | | | | The need for this can be avoided by passing the correct node to the device_bind() function. Signed-off-by: Simon Glass <sjg@chromium.org>
* | dm: Remove uses of device_bind_offset()Simon Glass2020-12-131-1/+3
| | | | | | | | | | | | | | This function is not needed since the standard device_bind() can be used instead. Signed-off-by: Simon Glass <sjg@chromium.org>
* | dm: core: Rename device_bind() to device_bind_offset()Simon Glass2020-12-131-1/+1
|/ | | | | | | | | This function is not necessary anymore, since device_bind_ofnode() does the same thing and works with both flattree and livetree. Rename it to indicate that it is special. Signed-off-by: Simon Glass <sjg@chromium.org>

* dm: core: Create a new header file for 'compat' featuresSimon Glass2020-02-051-0/+2
| | | | | | | | | | | | 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.

* pinctrl: meson: add support of drive-strength-microampGuillaume La Roque2019-06-121-1/+44
| | | | | | | | | | | drive-strength-microamp is a new feature needed for G12A SoC. the default DS setting after boot is usually 500uA and it is not enough for many functions. We need to be able to set the drive strength to reliably enable things like MMC, I2C, etc ...

* pinctrl: meson: add pinconf supportJerome Brunet2019-01-291-7/+94
| | | | | | | | | | | | Adding pinconf support is necessary to enable boot from SPI without breaking the eMMC. When booting from SPI, the ROM code leave pull downs on the eMMC pad. We need to set pinconf provided in DT to solve this Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Neil Armstrong <narmstrong@baylibre.com> [narmstrong: added missing comma in pinctrl-meson-axg-pmx.c]
* pinctrl: meson: Fix GPIO direction registers accessCarlo Caione2018-12-051-2/+2
| | | | | | | | | | | | The macros used to set the direction of the GPIO pins are misused, resulting in a wrong behavior when trying to read the GPIO input level from U-Boot. A better macro is also used when setting the output direction.

* 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>
