dt-bindings: gpio: Add a binding header for the MSC313 GPIO driver

2020-12-05T21:40:28Z

Header adds defines for the gpio number of each pad from the driver view. The gpio block seems to have enough registers for 128 lines but what line is mapped to a physical pin depends on the chip. The gpio block also seems to contain some registers that are not related to gpio but needed somewhere to go. Because of the above the driver itself uses the index of a pin's offset in an array of the possible offsets for a chip as the gpio number.

dt-bindings: gpio: Use Tegra186-specific include guard

2020-12-05T21:34:12Z

Use a unique include guard for the Tegra186 GPIO DT bindings header to avoid clashes with the DT bindings header for earlier chips. Signed-off-by: Thierry Reding Link: https://lore.kernel.org/r/20201127140852.123192-2-thierry.reding@gmail.com Signed-off-by: Linus Walleij

dt-bindings: gpio: document the new pull-up/pull-down flags

2019-02-13T08:07:43Z

This commit extends the flags that can be used in GPIO specifiers to indicate if a pull-up resistor or pull-down resistor should be enabled. While some pinctrl DT bindings already offer the capability of configuring pull-up/pull-down resistors at the pin level, a number of simple GPIO controllers don't have any pinmuxing capability, and therefore do not rely on the pinctrl DT bindings. Such simple GPIO controllers however sometimes allow to configure pull-up and pull-down resistors on a per-pin basis, and whether such resistors should be enabled or not is a highly board-specific HW characteristic. By using two additional bits of the GPIO flag specifier, we can easily allow the Device Tree to describe which GPIOs should have their pull-up or pull-down resistors enabled. Even though the two options are mutually exclusive, we still need two bits to encode at least three states: no pull-up/pull-down, pull-up, pull-down.

dt-bindings: tegra186-gpio: Add Tegra186 specific prefix

2018-12-07T10:07:12Z

Subsequent generations of Tegra, such as Tegra194, contain a completely different set of GPIOs. In order to clarify that the Tegra186 defines are indeed specific to Tegra186, change the prefix from TEGRA_ to TEGRA186_. Note that for now we need to keep the old definitions in place to avoid breaking compilation in file that use this header. Once all users have been converted to use the new defines, the old ones can be removed. Also note that this is only a naming change and doesn't affect device tree ABI.

Pull ARM SoC device tree updates from Arnd Bergmann: "This is the usual set of changes for device trees, with over 700 non-merged changesets. There is an ongoing set of dtc warning fixes and the usual bugfixes, cleanups and added device support. The most interesting bit as usual is support for new machines listed below: - The Allwinner H6 makes its debut with the Pine-H64 board, and we get two new machines based on its older siblings: the H5 based OrangePi Zero+ and the A64 based Teres-I Laptop from Olimex. On the 32-bit side, we add The Olimex som204 based on Allwinner A20, and the Banana Pi M2 Zero development board (based on H2). - NVIDIA adds support for Tegra194 aka "Xavier", plus their p2972 development board and p2888 CPU module. - The Nuvoton npcm750 is a BMC that was newly added, for now we only support running on the evaluation board. - STmicroelectronics stm32 gains support for the stm32mp157c and two evaluation boards. - The Toradex Colibri board family grows a few members based on the i.MX6ULL variant. - The Advantec DMS-BA16 is a Qseven module using the NXP i.MX6 family of chips. - The Phytec phyBOARD Mira is a family of industrial boards based on i.MX6. For now, four models get added. - TI am335x based PDU-001 is an industrial embedded machine used for traffic monitoring - The Aspeed platform now supports running on the BMC on the Qualcomm Centriq 2400 server - Samsung Exynos4 based Galaxy S3 is a family of mobile phones Qualcomm msm8974 based Galaxy S5 is a rather different phone made by the same company. - The Xilinx Zynq and ZynqMP platforms now gained a lot of dts file for the various boards made by Xilinx themselves, as well as the Digilent Zybo Z7. - The ARM Versatile family now supports the "IB2" interface board. - The Renesas H2 based "Stout" and the H3 based Salvator-X are more evaluation boards named after a kind of beer, as most of them are. The r8a77980 (V3H) based "Condor" apparently doesn't follow that tradition. ;-) - ROC-RK3328-CC is a simple developement board from the Libre Computer Project, based on the Rockchips RK3328 SoC - Haiku is another development board plus Qseven module based on Rockchips RK3368 and made by Theobroma Systems" * tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (701 commits) arm: dts: modify Nuvoton NPCM7xx device tree structure arm: dts: modify Makefile NPCM750 configuration name arm: dts: modify clock binding in NPCM750 device tree arm: dts: modify timer register size in NPCM750 device tree arm: dts: modify UART compatible name in NPCM750 device tree arm: dts: add watchdog device to NPCM750 device tree arm64: dts: uniphier: add ethernet node for PXs3 ARM: dts: uniphier: add pinctrl groups of ethernet for second instance arm: dts: kirkwood*.dts: use SPDX-License-Identifier for board using GPL-2.0+ arm: dts: kirkwood*.dts: use SPDX-License-Identifier for boards using GPL-2.0+/MIT arm: dts: kirkwood*.dts: use SPDX-License-Identifier for boards using GPL-2.0 arm: dts: armada-385-turris-omnia: use SPDX-License-Identifier arm: dts: armada-385-db-ap: use SPDX-License-Identifier arm: dts: armada-388-rd: use SPDX-License-Identifier arm: dts: armada-xp-db-xc3-24g4xg: use SPDX-License-Identifier arm: dts: armada-xp-db-dxbc2: use SPDX-License-Identifier arm: dts: armada-370-db: use SPDX-License-Identifier arm: dts: armada-*.dts: use SPDX-License-Identifier for most of the Armada based board arm: dts: armada-xp-98dx: use SPDX-License-Identifier for prestara 98d SoCs arm: dts: armada-*.dtsi: use SPDX-License-Identifier for most of the Armada SoCs ...
