2019-06-12pinctrl: meson: add support of drive-strength-microampGuillaume La Roque
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 ...

2019-06-12pinctrl: meson: add common function to get pins nameNeil Armstrong
In order to support the "pinmux status" command, add common function to get pins count and pin name. Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>
2019-04-23pinctrl: meson: add g12a supportJerome Brunet
Add pinctrl support for the Amlogic G12A SoC, which is very similar to the Amlogic AXG support but with an additionnal drive-strength register bank. Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>
2019-01-29pinctrl: meson: add pinconf supportJerome Brunet
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]
2018-12-05pinctrl: meson: Fix GPIO direction registers accessCarlo Caione
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.

2018-11-26pinctrl: meson: rework gx pmx functionJerome Brunet
In preparation of supporting the new Amlogix AGX SoCs, we need to move the Amlogic GX pinmux functions out of the common code to be able to add a different set of SoC specific pinmux functions for AXG.

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>

2017-02-08dm: 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.
