2019-06-12pinctrl: meson-gxbb: add hdmi related pinsMaxime Jourdan
The GXBB pinctrl is missing pins related to HDMI, namely hot plug detection (hpd) and I2C (sda + scl). This fixes HDMI support for GXBB in u-boot.

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-axg: add support for getting pinmux statusNeil Armstrong
In order to support the "pinmux status" command, use the common functions to get the pins count and names, and add the AXG specific function to get the current function from registers. Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>

2019-06-12pinctrl: meson-gx: fix GPIO_TEST_N and GPIOCLK_ groupsNeil Armstrong
The GPIO_TEST_N was in the wrong pmx group table, move it back with the AO groups, GPIODV_18 was missing, add it back, and finally the GPIOCLK_* group names were missing. 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>
2019-04-10pinctrl: meson: axg: Fix PIN and BANK offsetsGuillaume La Roque
Periphs bank offset must be applied on all pins and PMX bank to prevent issue in meson_pinconf_set call. Without offset on pins when a call to pinconf is done meson_gpio_calc_reg_and_bit return wrong offset. To avoid breaking pmx function offset is needed in pmx bank structure too.

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]
2018-12-07pinctrl: meson: axg: Fix GPIO pin offsetsCarlo Caione
The pin number (first and last) in the bank definition is missing the pin base offset shifting. This is causing a miscalculation when retrieving the register and pin offsets in the GPIO driver causing the 'gpio' command to drive the wrong pins / GPIOs in the second GPIO chip (the AO bank is driven correctly because the shifting is already 0).

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

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>

2017-06-01dm: 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.

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